Description
The STM32L4R5xx, STM32L4R7xx and STM32L4R9xx devices are an ultra-low-power
microcontrollers family (STM32L4+ Series) based on the high-performance
®
®
Arm Cortex -M4 32-bit RISC core. They operate at a frequency of up to 120 MHz.
The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all
®
the Arm single-precision data-processing instructions and all the data types. The Cortex-
M4 core also implements a full set of DSP (digital signal processing) instructions and a
memory protection unit (MPU) which enhances the application’s security.
These devices embed high-speed memories (2 Mbytes of Flash memory and 640 Kbytes of
SRAM), a flexible external memory controller (FSMC) for static memories (for devices with
packages of 100 pins and more), two OctoSPI Flash memories interface (available on all
packages) and an extensive range of enhanced I/Os and peripherals connected to two APB
buses, two AHB buses and a 32-bit multi-AHB bus matrix.
The STM32L4Rxxx devices embed several protection mechanisms for embedded Flash
memory and SRAM: readout protection, write protection, proprietary code readout
protection and a firewall.
These devices offer a fast 12-bit ADC (5 Msps), two comparators, two operational
amplifiers, two DAC channels, an internal voltage reference buffer, a low-power RTC, two
general-purpose 32-bit timer, two 16-bit PWM timers dedicated to motor control, seven
general-purpose 16-bit timers, and two 16-bit low-power timers. The devices support four
digital filters for external sigma delta modulators (DFSDM). In addition, up to 24 capacitive
sensing channels are available.
They also feature standard and advanced communication interfaces such as:
•

Four I2Cs
Three SPIs
Three USARTs, two UARTs and one low-power UART
Two SAIs
One SDMMC
One CAN
One USB OTG full-speed
Camera interface
DMA2D controller
The devices operate in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C
junction) temperature ranges from a 1.71 to 3.6 V for V power supply when using internal
DD
LDO regulator and a 1.05 to 1.32 V V
power supply when using external SMPS supply.
DD12
A comprehensive set of power-saving modes allows the design of low-power applications.
Some independent power supplies are supported like an analog independent supply input
for ADC, DAC, OPAMPs and comparators, a 3.3 V dedicated supply input for USB and up to
14 I/Os, which can be supplied independently down to 1.08 V. A VBAT input allows to
backup the RTC and backup the registers. Dedicated V
power supplies can be used to
DD12
bypass the internal LDO regulator when connected to an external SMPS.
The STM32L4Rxxx family offers six packages from 100-pin to 169-pin.

Functional overview
3.1
Arm® Cortex®-M4 core with FPU
®
®
®
The Arm Cortex -M4 with FPU processor is the latest generation of Arm processors for
embedded systems. It was developed to provide a low-cost platform that meets the needs of
the MCU implementation, with a reduced pin count and with low-power consumption, while
delivering outstanding computational performance and an advanced response to interrupts.
®
®
The Arm Cortex -M4 with FPU 32-bit RISC processor features an exceptional code-
®
efficiency, delivering the expected high-performance from an Arm core in a memory size
usually associated with 8-bit and 16-bit devices.
The processor supports a set of DSP instructions which allows an efficient signal processing
and a complex algorithm execution. Its single precision FPU speeds up the software
development by using metalanguage development tools to avoid saturation.
®
®
With its embedded Arm core, the STM32L4Rxxx family is compatible with all Arm tools
and software.
Figure 1 shows the general block diagram of the STM32L4Rxxx family devices.
3.2
Adaptive real-time memory accelerator (ART Accelerator)
The ART Accelerator is a memory accelerator that is optimized for the STM32 industry-
®
®
standard Arm Cortex -M4 processors. It balances the inherent performance advantage of
®
®
the Arm Cortex -M4 over Flash memory technologies, which normally requires the
processor to wait for the Flash memory at higher frequencies.
To release the processor near 150 DMIPS performance at 120 MHz, the accelerator
implements an instruction prefetch queue and a branch cache, which increases the
program’s execution speed from the Flash memory. Based on CoreMark benchmark, the
performance achieved thanks to the ART accelerator is equivalent to 0 wait state program
execution from the Flash memory at a CPU frequency of up to 120 MHz.
3.3
Memory protection unit
The memory protection unit (MPU) is used to manage the CPU accesses to the memory
and to prevent one task to accidentally corrupt the memory or the resources used by any
other active task. This memory area is organized into up to eight protected areas, which can
be divided in up into eight subareas each. The protection area sizes range between 32
bytes and the whole 4 gigabytes of addressable memory.
The MPU is especially helpful for applications where some critical or certified code has to be
protected against the misbehavior of other tasks. It is usually managed by an RTOS (real-
time operating system). If a program accesses a memory location that is prohibited by the
MPU, the RTOS can detect it and take action. In an RTOS environment, the kernel can
dynamically update the MPU area setting based on the process to be executed.
The MPU is optional and can be bypassed for applications that do not need it.

3.4
Embedded Flash memory
The STM32L4Rxxx devices feature 2 Mbytes of embedded Flash memory which is
available for storing programs and data.
The Flash interface features:
–
–
Single or dual bank operating modes
Read-while-write (RWW) in dual bank mode
This feature allows to perform a read operation from one bank while an erase or program
operation is performed to the other bank. The dual bank boot is also supported. Each bank
contains 256 pages of 4 or 8 Kbytes (depending on the read access width).
Flexible protections can be configured thanks to the option bytes:
• Readout protection (RDP) to protect the whole memory. Three levels of protection are
available:
– Level 0: no readout protection
– Level 1: memory readout protection; the Flash memory cannot be read from or written
to if either the debug features are connected or the boot in RAM or bootloader are
selected
– Level 2: chip readout protection; the debug features (Cortex-M4 JTAG and serial
wire), the boot in RAM and the bootloader selection are disabled (JTAG fuse). This
selection is irreversible.

•
Proprietary code readout protection (PCROP): a part of the Flash memory can be
protected against read and write from third parties. The protected area is execute-only
and it can only be reached by the STM32 CPU as an instruction code, while all other
accesses (DMA, debug and CPU data read, write and erase) are strictly prohibited:
–
–
In single bank mode, two areas can be selected with 128-bit granularity.
In dual bank mode, one area per bank can be selected with 64-bit granularity.
An additional option bit (PCROP_RDP) allows to select if the PCROP area is erased or
not when the RDP protection is changed from Level 1 to Level 0.
The whole non-volatile memory embeds the error correction code (ECC) feature supporting:
•
•
•
Single error detection and correction
Double error detection
The address of the ECC fail can be read in the ECC register.
3.5
Embedded SRAM
The STM32L4R5xx, STM32L4R7xx and STM32L4R9xx devices feature 640 Kbytes of
embedded SRAM. This SRAM is split into three blocks:
•
•
192 Kbytes mapped at address 0x2000 0000 (SRAM1).
64 Kbytes located at address 0x1000 0000 with hardware parity check (SRAM2).
This memory is also mapped at address 0x2003 0000 offering a contiguous address
space with the SRAM1.
This block is accessed through the ICode/DCode buses for maximum performance.
These 64 Kbytes SRAM can also be retained in Standby mode.
The SRAM2 can be write-protected with 1 Kbyte granularity.
•
384 Kbytes mapped at address 0x2004 0000 - (SRAM3).
The memory can be accessed in read/write at CPU clock speed with 0 wait states.

Firewall
These devices embed a firewall which protects code sensitive and secure data from any
access performed by a code executed outside of the protected areas.
Each illegal access generates a reset which kills immediately the detected intrusion.

Functional overview
STM32L4R5xx, STM32L4R7xx and STM32L4R9xx
The main features of the firewall are the following:
•
Three segments can be protected and defined thanks to the firewall registers:
–
Code segment (located in Flash or SRAM1 if defined as executable protected
area)
–
–
Non-volatile data segment (located in Flash)
Volatile data segment (located in SRAM1)
•
•
The start address and the length of each segment are configurable:
–
–
–
Code segment: up to 2048 Kbytes with granularity of 256 bytes
Non-volatile data segment: up to 2048 Kbytes with granularity of 256 bytes
Volatile data segment: up to 192 Kbytes of SRAM1 with a granularity of 64 bytes
Specific mechanism implemented to open the firewall to get access to the protected
areas (call gate entry sequence)
•
•
Volatile data segment can be shared or not with the non-protected code
Volatile data segment can be executed or not depending on the firewall configuration
The Flash readout protection must be set to level 2 in order to reach the expected level of
protection.
3.8
Boot modes
At startup, a BOOT0 pin and an nBOOT1 option bit are used to select one of three boot
options:
•
•
•
Boot from user Flash
Boot from system memory
Boot from embedded SRAM
The BOOT0 value may come from the PH3-BOOT0 pin or from an option bit depending on
the value of a user option bit to free the GPIO pad if needed.
A Flash empty-check mechanism is implemented to force the boot from system Flash if the
first Flash memory location is not programmed and if the boot selection is configured to boot
from main Flash.
The boot loader is located in the system memory. It is used to reprogram the Flash memory
by using USART, I2C, SPI, CAN or USB OTG FS in device mode through the DFU (device
firmware upgrade).
3.9
Cyclic redundancy check calculation unit (CRC)
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code using a
configurable generator with polynomial value and size.
Among other applications, the CRC-based techniques are used to verify data transmission
or storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a mean to verify
the Flash memory integrity.
The CRC calculation unit helps to compute a signature of the software during runtime, which
can be ulteriorly compared with a reference signature generated at link-time and which can
be stored at a given memory location.

Power supply supervisor
The STM32L4R5xx, STM32L4R7xx and STM32L4R9xx devices have an integrated ultra-
low-power Brownout reset (BOR) active in all modes (except for Shutdown mode). The BOR
ensures proper operation of the devices after power-on and during power-down. The
devices remain in reset mode when the monitored supply voltage V is below a specified
DD
threshold, without the need for an external reset circuit.
The lowest BOR level is 1.71 V at power on, and other higher thresholds can be selected
through option bytes.The devices feature an embedded programmable voltage detector
(PVD) that monitors the V power supply and compares it to the VPVD threshold.
DD
An interrupt can be generated when V drops below the VPVD threshold and/or when V

DD
is higher than the VPVD threshold. The interrupt service routine can then generate a
warning message and/or put the MCU into a safe state. The PVD is enabled by software.
In addition, the devices embed a peripheral voltage monitor which compares the
independent supply voltages V
, V
, V
with a fixed threshold in order to ensure
DDA DDUSB DDIO2
that the peripheral is in its functional supply range.

Voltage regulator
Two embedded linear voltage regulators supply most of the digital circuitries: the main
regulator (MR) and the low-power regulator (LPR).
•
•
The MR is used in the Run and Sleep modes and in the Stop 0 mode.
The LPR is used in Low-power run, Low-power sleep, Stop 1 and Stop 2 modes. It is
also used to supply the 64 Kbytes SRAM2 in standby with RAM2 retention.
•
Both regulators are in power-down while they are in standby and Shutdown modes: the
regulator output is in high impedance, and the kernel circuitry is powered down thus
inducing zero consumption.

Functional overview
STM32L4R5xx, STM32L4R7xx and STM32L4R9xx
The ultra-low-power STM32L4Rxxx devices support dynamic voltage scaling to optimize its
power consumption in Run mode. The voltage from the main regulator that supplies the
logic (VCORE) can be adjusted according to the system’s maximum operating frequency.
The main regulator operates in the following ranges:
•
•
•
Range 1 boost mode with the CPU running at up to 120 MHz.
Range 1 normal mode with the CPU running at up to 80 MHz.
Range 2 with a maximum CPU frequency of 26 MHz. All peripheral clocks are also
limited to 26 MHz.
The VCORE can be supplied by the low-power regulator, the main regulator being switched
off. The system is then in Low-power run mode.
•
Low-power run mode with the CPU running at up to 2 MHz. Peripherals with
independent clock can be clocked by the HSI16.
When the MR is in use, the device with the external SMPS option allows to force an external
supply on the VDD12 supply pins.
V
CORE
When V
is forced by an external source and that it is higher than the output of the
DD12
internal LDO, the current is taken from this external supply and the overall power efficiency
is significantly improved if using an external step down DC/DC converter.
Note:
The USB and DSIHOST can only be used when the main regulator is in range1 boost mode.

Low-power modes
The ultra-low-power STM32L4Rxxx devices support seven low-power modes to achieve the best compromise between low-power
consumption, short startup time, available peripherals and available wake-up sources. Table 4 shows the related STM32L4Rxxx

Functional overview
STM32L4R5xx, STM32L4R7xx and STM32L4R9xx
By default, the microcontroller is in Run mode after a system or a power reset. It is up to the
user to select one of the low-power modes described below:
•
Sleep mode
In Sleep mode, only the CPU is stopped. All peripherals continue to operate and can
wake up the CPU when an interrupt/event occurs.
•
Low-power run mode
This mode is achieved with VCORE supplied by the low-power regulator to minimize
the regulator's operating current. The code can be executed from SRAM or from Flash,
and the CPU frequency is limited to 2 MHz. The peripherals with independent clock can
be clocked by HSI16.
•
•
Low-power sleep mode
This mode is entered from the Low-power run mode. Only the CPU clock is stopped.
When wakeup is triggered by an event or an interrupt, the system reverts to the Low-
power run mode.
Stop 0, Stop 1 and Stop 2 modes
Stop mode achieves the lowest power consumption while retaining the content of
SRAM and registers. All clocks in the VCORE domain are stopped, the PLL, the MSI
RC, the HSI16 RC and the HSE crystal oscillators are disabled. The LSE or LSI is still
running.
The RTC can remain active (Stop mode with RTC, Stop mode without RTC).
Some peripherals with wake-up capability can enable the HSI16 RC during Stop mode
to detect their wake-up condition.
Three Stop modes are available: Stop 0, Stop 1 and Stop 2 modes. In Stop 2 mode,
most of the VCORE domain is put in a lower leakage mode.
Stop 1 offers the largest number of active peripherals and wakeup sources, a smaller
wakeup time but a higher consumption than Stop 2. In Stop 0 mode, the main regulator
remains ON, allowing a very fast wakeup time but with much higher consumption.
The system clock when exiting from Stop 0, Stop 1 or Stop 2 modes can be either MSI
up to 48 MHz or HSI16, depending on software configuration.
•
Standby mode
The Standby mode is used to achieve the lowest power consumption with BOR. The
internal regulator is switched off so that the VCORE domain is powered off. The PLL,
the MSI RC, the HSI16 RC and the HSE crystal oscillators are also switched off.
The RTC can remain active (Standby mode with RTC, Standby mode without RTC).
The Brownout reset (BOR) always remains active in Standby mode.
The state of each I/O during Standby mode can be selected by software: I/O with
internal pull-up, internal pull-down or floating.
After entering Standby mode, SRAM1, SRAM3 and register contents are lost except for
registers in the Backup domain and Standby circuitry. Optionally, SRAM2 can be
32/307

Functional overview
retained in Standby mode, supplied by the low-power regulator (standby with RAM2
retention mode).
The device exits Standby mode when an external reset (NRST pin), an IWDG reset,
WKUP pin event (configurable rising or falling edge), or an RTC event occurs (alarm,
periodic wakeup, timestamp, tamper) or a failure is detected on LSE (CSS on LSE).
The system clock after wakeup is MSI up to 8 MHz.
•
Shutdown mode
The Shutdown mode allows to achieve the lowest power consumption. The internal
regulator is switched off so that the VCORE domain is powered off. The PLL, the
HSI16, the MSI, the LSI and the HSE oscillators are also switched off.
The RTC can remain active (Shutdown mode with RTC, Shutdown mode without RTC).
The BOR is not available in Shutdown mode. No power voltage monitoring is possible
in this mode, therefore the switch to Backup domain is not supported.
SRAM1, SRAM2, SRAM3 and register contents are lost except for registers in the
Backup domain.
The device exits Shutdown mode when an external reset (NRST pin), a WKUP pin
event (configurable rising or falling edge), or an RTC event occurs (alarm, periodic
wakeup, timestamp, tamper).
The system clock after wakeup is MSI at 4 MHz.

1. Legend: Y = yes (enable). O = optional (disable by default, can be enabled by software). - = not available.
Gray cells highlight the wakeup capability in each mode.
2. The Flash can be configured in power-down mode. By default, it is not in power-down mode.
3. The SRAM clock can be gated on or off. In Stop 2 mode, the content of SRAM3 is preserved or not depending on the
RRSTP bit in PWR_CR1 register.
4. SRAM2 content is preserved when the bit RRS is set in PWR_CR3 register.
5. Some peripherals with wakeup from Stop capability can request HSI16 to be enabled. In this case, HSI16 is woken up by
the peripheral, and only feeds the peripheral which requested it. HSI16 is automatically put off when the peripheral does not
need it anymore.
6. UART and LPUART reception is functional in Stop mode, and generates a wakeup interrupt on Start, address match or
received frame event.
7. I2C address detection is functional in Stop mode, and generates a wakeup interrupt in case of address match.
8. Voltage scaling range 1 only.
9. I/Os can be configured with internal pull-up, pull-down or floating in Standby mode.
10. The I/Os with wakeup from standby/shutdown capability are: PA0, PC13, PE6, PA2, PC5.
11. I/Os can be configured with internal pull-up, pull-down or floating in Shutdown mode but the configuration is lost when
exiting the Shutdown mode.
3.10.5
Reset mode
In order to improve the consumption under reset, the I/Os state under and after reset is
“analog state” (the I/O schmitt trigger is disable). In addition, the internal reset pull-up is
deactivated when the reset source is internal.

VBAT operation
The VBAT pin allows to power the device VBAT domain from an external battery, an external
supercapacitor, or from V when there is no external battery and when an external
DD
supercapacitor is present. The VBAT pin supplies the RTC with LSE and the backup
registers. Three anti-tamper detection pins are available in VBAT mode.
The VBAT operation is automatically activated when V is not present. An internal VBAT
DD
battery charging circuit is embedded and can be activated when V is present.

Note:
When the microcontroller is supplied from VBAT, neither external interrupts nor RTC
alarm/events exit the microcontroller from the VBAT operation.

Interconnect matrix
Several peripherals have direct connections between them, which allow autonomous
communication between them and support the saving of CPU resources (thus power supply
consumption). In addition, these hardware connections allow fast and predictable latency.
Depending on the peripherals, these interconnections can operate in Run, Sleep, Low-
power run and Sleep, Stop 0, Stop 1 and Stop 2 modes. See Table 6 for more details.

Clocks and startup
The clock controller (see Figure 7) distributes the clocks coming from the different
oscillators to the core and to the peripherals. It also manages the clock gating for low-power
modes and ensures the clock robustness. It features:
•
Clock prescaler: to get the best trade-off between speed and current consumption,
the clock frequency to the CPU and peripherals can be adjusted by a programmable
prescaler.
•
•
•
Safe clock switching: clock sources can be changed safely on the fly in Run mode
through a configuration register.
Clock management: to reduce the power consumption, the clock controller can stop
the clock to the core, individual peripherals or memory.
System clock source: four different clock sources can be used to drive the master
clock SYSCLK:
–
4 to 48 MHz high-speed external crystal or ceramic resonator (HSE), that can
supply a PLL. The HSE can also be configured in bypass mode for an external
clock. The HSE must be available when the DSI-HOST peripheral is used.
–
–
16 MHz high-speed internal RC oscillator (HSI16), trimmable by software, that can
supply a PLL
Multispeed internal RC oscillator (MSI), trimmable by software, able to generate
12 frequencies from 100 kHz to 48 MHz. When a 32.768 kHz clock source is
available in the system (LSE), the MSI frequency can be automatically trimmed by
hardware to reach better than ±0.25% accuracy. In this mode the MSI can feed the
USB device, saving the need of an external high-speed crystal (HSE). The MSI
can supply a PLL.
–
System PLL which can be fed by HSE, HSI16 or MSI, with a maximum frequency
at 120 MHz.
•
•
RC48 with clock recovery system (HSI48): internal 48 MHz clock source (HSI48)can
be used to drive the USB, the SDMMC or the RNG peripherals. This clock can be
output on the MCO.
Auxiliary clock source: two ultra-low-power clock sources that can be used to drive
the real-time clock:
–
–
32.768 kHz low-speed external crystal (LSE), supporting four drive capability
modes. The LSE can also be configured in bypass mode for an external clock.
32 kHz low-speed internal RC (LSI), also used to drive the independent watchdog.
The LSI clock accuracy is ±5% accuracy.
•
Peripheral clock sources: several peripherals (USB, SDMMC, RNG, SAI, USARTs,
I2Cs, LPTimers, ADC) have their own independent clock whatever the system clock.
Three PLLs, each having three independent outputs allowing the highest flexibility, can
generate independent clocks for the ADC, the USB/SDMMC/RNG, the two SAIs, LCD-
TFT and DSI-HOST. When using DSI-HOST peripheral, the high-speed external crystal
(HSE) must be available.
•
•
Startup clock: after reset, the microcontroller restarts by default with an internal 4 MHz
clock (MSI). The prescaler ratio and clock source can be changed by the application
program as soon as the code execution starts.
Clock security system (CSS): this feature can be enabled by software. If a HSE clock
failure occurs, the master clock is automatically switched to HSI16 and a software

interrupt is generated if enabled. LSE failure can also be detected and generated an
interrupt.
•
Clock-out capability:
–
MCO (microcontroller clock output): it outputs one of the internal clocks for
external use by the application
–
LSCO (low-speed clock output): it outputs LSI or LSE in all low-power modes
(except VBAT).
Several prescalers allow to configure the AHB frequency, the high speed APB (APB2) and
the low-speed APB (APB1) domains. The maximum frequency of the AHB and the APB
domains is 120 MHz.

General-purpose inputs/outputs (GPIOs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the
GPIO pins are shared with digital or analog alternate functions. Fast I/O toggling can be
achieved thanks to their mapping on the AHB2 bus.
The I/Os alternate function configuration can be locked if needed following a specific
sequence in order to avoid spurious writing to the I/Os registers.
3.14
Direct memory access controller (DMA)
The device embeds 2 DMAs. Refer to Table 7: DMA implementation for the features
implementation.
Direct memory access (DMA) is used in order to provide a high-speed data transfer
between peripherals and memory as well as from memory to memory. Data can be quickly
moved by DMA without any CPU actions. This keeps the CPU resources free for other
operations.
The two DMA controllers have 14 channels in total, each one dedicated to manage memory
access requests from one or more peripherals. Each controller has an arbiter for handling
the priority between DMA requests.
The DMA supports:
•
14 independently configurable channels (requests)
–
Each channel is connected to a dedicated hardware DMA request, a software
trigger is also supported on each channel. This configuration is done by software.
•
•
Priorities between requests from channels of one DMA are both software
programmable (4 levels: very high, high, medium, low) or hardware programmable in
case of equality (request 1 has priority over request 2, etc.)
Independent source and destination transfer size (byte, half word, word), emulating
packing and unpacking. Source/destination addresses must be aligned on the data size
•
•
Support for circular buffer management
3 event flags (DMA half transfer, DMA transfer complete and DMA transfer error)
logically ORed together in a single interrupt request for each channel
•
•
•
•
Memory-to-memory transfer
Peripheral-to-memory, memory-to-peripheral, and peripheral-to-peripheral transfers
Access to Flash, SRAM, APB and AHB peripherals as source and destination
Programmable number of data to be transferred: up to 65536

DMA request router (DMAMux)
When a peripheral indicates a request for DMA transfer by setting its DMA request line, the
DMA request is pending until it is served and the corresponding DMA request line is reset.
The DMA request router allows to route the DMA control lines between the peripherals and
the DMA controllers of the product.
An embedded multi-channel DMA request generator can be considered as one of such
peripherals. The routing function is ensured by a multi-channel DMA request line
multiplexer. Each channel selects a unique set of DMA control lines, unconditionally or
synchronously with events on synchronization inputs.
For simplicity, the functional description is limited to DMA request lines. The other DMA
control lines are not shown in figures or described in the text. The DMA request generator
produces DMA requests following events on DMA request trigger inputs.

3.19.1
Temperature sensor
The temperature sensor (TS) generates a voltage V that varies linearly with temperature.
TS
The temperature sensor is internally connected to the ADC1_IN17 input channels which is
used to convert the sensor output voltage into a digital value.
The sensor provides good linearity but it has to be calibrated to obtain good overall
accuracy of the temperature measurement. As the offset of the temperature sensor varies
from chip to chip due to process variation, the uncalibrated internal temperature sensor is
suitable for applications that detect temperature changes only.
To improve the accuracy of the temperature sensor measurement, each device is
individually factory-calibrated by ST. The temperature sensor factory calibration data are
stored by ST in the system memory area, accessible in read-only mode.

3.30.1
Advanced-control timer (TIM1, TIM8)
The advanced-control timers can each be seen as a three-phase PWM multiplexed on six
channels. They have complementary PWM outputs with programmable inserted dead-
times. They can also be seen as complete general-purpose timers.
The four independent channels can be used for:
•
•
•
Input capture
Output compare
PWM generation (edge or center-aligned modes) with full modulation capability (0-
100%)
•
One-pulse mode output
In debug mode, the advanced-control timer counter can be frozen and the PWM outputs
disabled in order to turn off any power switches driven by these outputs.
Many features are shared with the general-purpose TIMx timers (described in
Section 3.30.2) using the same architecture, so the advanced-control timers can work
together with the TIMx timers via the Timer Link feature for synchronization or event
chaining.

3.30.5
Independent watchdog (IWDG)
The independent watchdog is based on a 12-bit downcounter and an 8-bit prescaler. It is
clocked from an independent 32 kHz internal RC (LSI) and as it operates independently
from the main clock, it can operate in Stop and Standby modes. It can be used either as a
watchdog to reset the device when a problem occurs, or as a free running timer for
application timeout management. It is hardware or software configurable through the option
bytes. The counter can be frozen in debug mode.

Real-time clock (RTC) and backup registers
The RTC is an independent BCD timer/counter. It supports the following features:
•
Calendar with subsecond, seconds, minutes, hours (12 or 24 format), week day, date,
month, year, in BCD (binary-coded decimal) format
•
•
•
Automatic correction for 28, 29 (leap year), 30, and 31 days of the month
Two programmable alarms
On-the-fly correction from 1 to 32767 RTC clock pulses. This can be used to
synchronize it with a master clock
•
•
Reference clock detection: a more precise second source clock (50 or 60 Hz) can be
used to enhance the calendar precision
Digital calibration circuit with 0.95 ppm resolution, to compensate for quartz crystal
inaccuracy
•
•
Three anti-tamper detection pins with programmable filter
Timestamp feature which can be used to save the calendar content. This function can
be triggered by an event on the timestamp pin, or by a tamper event, or by a switch to
VBAT mode
•
17-bit auto-reload wakeup timer (WUT) for periodic events with programmable
resolution and period
The RTC and the 32 backup registers are supplied through a switch that takes power either
from the V supply when present or from the VBAT pin.
DD
The backup registers are 32-bit registers used to store 128 bytes of user application data
when VDD power is not present. They are not reset by a system or power reset, or when the
device wakes up from standby or Shutdown mode.
The RTC clock sources can be:
•
•
•
•
A 32.768 kHz external crystal (LSE)
An external resonator or oscillator (LSE)
The internal low-power RC oscillator (LSI, with typical frequency of 32 kHz)
The high-speed external clock (HSE) divided by 32
The RTC is functional in VBAT mode and in all low-power modes when it is clocked by the
LSE. When clocked by the LSI, the RTC is not functional in VBAT mode, but is functional in
all low-power modes except Shutdown mode.
All RTC events (alarm, wake-up timer, Timestamp or Tamper) can generate an interrupt and
wakeup the device from the low-power modes.

Universal synchronous/asynchronous receiver transmitter
(USART)
The STM32L4Rxxx devices have three embedded universal synchronous receiver
transmitters (USART1, USART2 and USART3) and two universal asynchronous receiver
transmitters (UART4, UART5).
These interfaces provide asynchronous communication, IrDA SIR ENDEC support,
multiprocessor communication mode, single-wire half-duplex communication mode and
have LIN master/slave capability. They provide hardware management of the CTS and RTS
signals, and RS485 driver enable. They are able to communicate at speeds of up to
10 Mbit/s.
The USART1, USART2 and USART3 also provide a Smartcard mode (ISO 7816 compliant)
and an SPI-like communication capability.
All USART have a clock domain independent from the CPU clock, allowing the USARTx
(x=1,2,3,4,5) to wake up the MCU from Stop mode using baudrates up to 200 Kbaud. The
wake up events from Stop mode are programmable and can be:
•
•
•
Start bit detection
Any received data frame
A specific programmed data frame
All USART interfaces can be served by the DMA controller.

Low-power universal asynchronous receiver transmitter
(LPUART)
The STM32L4Rxxx devices embed one low-power UART. The LPUART supports
asynchronous serial communication with minimum power consumption. It supports half-
duplex single-wire communication and modem operations (CTS/RTS). It allows
multiprocessor communication.
The LPUART has a clock domain independent from the CPU clock, and can wakeup the
system from Stop mode using baudrates up to 220 Kbaud. The wake up events from Stop
mode are programmable and can be:
•
•
•
Start bit detection
Any received data frame
A specific programmed data frame
Only a 32.768 kHz clock (LSE) is needed to allow LPUART communication up to 9600
baud. Therefore, even in Stop mode, the LPUART can wait for an incoming frame while
having an extremely low energy consumption. Higher speed clock can be used to reach
higher baudrates.
The LPUART interface can be served by the DMA controller.
3.35
3.36
Serial peripheral interface (SPI)
Three SPI interfaces allow communication up to slave modes, in half-duplex, full-duplex and
simplex modes. The 3-bit prescaler gives eight master mode frequencies and the frame size
is configurable from 4 bits to 16 bits. The SPI interfaces support NSS pulse mode, TI mode
and hardware CRC calculation.
All SPI interfaces can be served by the DMA controller.
Serial audio interfaces (SAI)
The STM32L4Rxxx devices embed two SAI. Refer to Table 13: SAI implementation for the
features implementation. The SAI bus interface handles communications between the
microcontroller and the serial audio protocol.

transceivers. The USB OTG FS peripheral is compliant with the USB 2.0 specification and
with the OTG 2.0 specification. It has software-configurable endpoint setting and supports
suspend/resume.
The USB OTG controller requires a dedicated 48 MHz clock that can be provided by the
internal multispeed oscillator (MSI) automatically trimmed by 32.768 kHz external oscillator
(LSE).This allows to use the USB device without external high speed crystal (HSE).
The major features are:
•
•
•
•
•
•
•
•
•
•
Combined Rx and Tx FIFO size of 1.25 Kbytes with dynamic FIFO sizing
Supports the session request protocol (SRP) and host negotiation protocol (HNP)
One bidirectional control endpoint + 5 IN endpoints + 5 OUT endpoints
Eight host channels with periodic OUT support

OTG 2.0 Supports ADP (Attach detection Protocol)
USB 2.0 LPM (Link Power Management) support
Battery charging specification revision 1.2 support
Internal FS OTG PHY support
For OTG/Host modes, a power switch is needed in case bus-powered devices are
connected.
The synchronization for this oscillator can also be taken from the USB data stream itself
(SOF signalization) which allows crystal less operation.
3.40
3.41
Clock recovery system (CRS)
The devices embed a special block which allows automatic trimming of the internal 48 MHz
oscillator to guarantee its optimal accuracy over the whole device operational range. This
automatic trimming is based on the external synchronization signal, which could be either
derived from USB SOF signalization, from LSE oscillator, from an external signal on
CRS_SYNC pin or generated by user software. For faster lock-in during startup it is also
possible to combine automatic trimming with manual trimming action.

OctoSPI interface (OctoSPI)
The OctoSPI is a specialized communication interface targetting single, dual, quad or octal
SPI memories. It can operate in any of the three following modes:
•
•
Indirect mode: all the operations are performed using the OctoSPI registers
Status polling mode: the external memory status register is periodically read and an
interrupt can be generated in case of flag setting
•
Memory-mapped mode: the external memory is memory mapped and is seen by the
system as if it were an internal memory supporting read and write operation
The OctoSPI supports two frame formats:
•
Classical frame format with command, address, alternate byte, dummy cycles and data
phase over 1, 2, 4 or 8 data pins
TM
•
HyperBus frame format
The OctoSPI offers the following features:
•
•

Serial wire JTAG debug port (SWJ-DP)
®
The Arm SWJ-DP interface is embedded, and is a combined JTAG and serial wire debug
port that enables either a serial wire debug or a JTAG probe to be connected to the target.
Debug is performed using two pins only instead of five required by the JTAG (JTAG pins
could be re-used as GPIO with alternate function): the JTAG TMS and TCK pins are shared
with SWDIO and SWCLK, respectively, and a specific sequence on the TMS pin is used to
switch between JTAG-DP and SW-DP.

1. PC13, PC14 and PC15 are supplied through the power switch. Since the switch only sinks a limited amount of current
(3 mA), the use of GPIOs PC13 to PC15 in output mode is limited:
- The speed should not exceed 2 MHz with a maximum load of 30 pF
- These GPIOs must not be used as current sources (for example to drive a LED).
2. After a Backup domain power-up, PC13, PC14 and PC15 operate as GPIOs. Their function then depends on the content of the RTC registers which are not reset by the
system reset. For details on how to manage these GPIOs, refer to the Backup domain and RTC register descriptions in the RM0432 reference manual.
3. NC (not-connected) balls must be left unconnected. However, non connected (NC) GPIOS are not bonded. They must be configured by software to output push-pull and
forced to 0 in the output data register to avoid extra current consumption in low-power modes.
4. After reset, these pins are configured as JTAG/SW debug alternate functions, and the internal pull-up on PA15, PA13, PB4 pins and the internal pull-down on PA14 pin are
activated.

3. This current consumption must be correctly distributed over all I/Os and control pins. The total output
current must not be sunk/sourced between two consecutive power supply pins referring to high pin count
QFP packages.
4. Positive injection (when VIN > VDDIOx) is not possible on these I/Os and does not occur for input voltages
lower than the specified maximum value.
5. A negative injection is induced by VIN < VSS. IINJ(PIN) must never be exceeded. Refer also to Table 18:

Supply current characteristics
The current consumption is a function of several parameters and factors such as the
operating voltage, ambient temperature, I/O pin loading, device software configuration,
operating frequencies, I/O pin switching rate, program location in memory and executed
binary code
The current consumption is measured as described in Figure 26: Current consumption
measurement.
Typical and maximum current consumption
The MCU is placed under the following conditions:
•
•
•
All I/O pins are in analog input mode
All peripherals are disabled except when explicitly mentioned
The Flash memory access time is adjusted with the minimum wait states number,
depending on the f
frequency (refer to the table “Number of wait states according
HCLK
to CPU clock (HCLK) frequency” available in the RM0432 reference manual).
•
•
When the peripherals are enabled f = f
PCLK
HCLK
The voltage scaling Range 1 is adjusted to f
frequency as follows:
HCLK
–
–
Voltage Range 1 Boost mode for 80 MHz < f
<= 120 MHz
HCLK
Voltage Range 1 Normal mode for 26 MHz < f
<= 80 MHz
HCLK
The parameters given in Table 25 to Table 39 are derived from tests performed under
ambient temperature and supply voltage conditions summarized in Table 21: General
operating conditions.

Electrical characteristics
STM32L4R5xx, STM32L4R7xx and STM32L4R9xx
I/O system current consumption
The current consumption of the I/O system has two components: static and dynamic.
I/O static current consumption
All the I/Os used as inputs with pull-up generate current consumption when the pin is
externally held low. The value of this current consumption can be simply computed by using
the pull-up/pull-down resistors values given in Table 75: I/O static characteristics.
For the output pins, any external pull-down or external load must also be considered to
estimate the current consumption.
Additional I/O current consumption is due to I/Os configured as inputs if an intermediate
voltage level is externally applied. This current consumption is caused by the input Schmitt
trigger circuits used to discriminate the input value. Unless this specific configuration is
required by the application, this supply current consumption can be avoided by configuring
these I/Os in analog mode. This is notably the case of ADC input pins which should be
configured as analog inputs.
Caution:
Any floating input pin can also settle to an intermediate voltage level or switch inadvertently,
as a result of external electromagnetic noise. To avoid current consumption related to
floating pins, they must either be configured in analog mode, or forced internally to a definite
digital value. This can be done either by using pull-up/down resistors or by configuring the
pins in output mode.
I/O dynamic current consumption
In addition to the internal peripheral current consumption measured previously (see
Table 52: Low-power mode wakeup timings), the I/Os used by an application also contribute
to the current consumption. When an I/O pin switches, it uses the current from the I/O
supply voltage to supply the I/O pin circuitry and to charge/discharge the capacitive load
(internal or external) connected to the pin:
ISW = VDDIOx × fSW × C
where
I
is the current sunk by a switching I/O to charge/discharge the capacitive load
SW
V
is the I/O supply voltage
DDIOx
f
is the I/O switching frequency
SW
C is the total capacitance seen by the I/O pin: C = C + C
+ C
S
INT
EXT
C is the PCB board capacitance including the pad pin.
S
The test pin is configured in push-pull output mode and is toggled by software at a fixed
frequency.

On-chip peripheral current consumption
Electrical characteristics
The current consumption of the on-chip peripherals is given in Table 52. The MCU is placed
under the following conditions:
•
•
All I/O pins are in Analog mode
The given value is calculated by measuring the difference of the current consumptions:
–
–
when the peripheral is clocked on
when the peripheral is clocked off
•
•
Ambient operating temperature and supply voltage conditions summarized in Table 18:
Voltage characteristics
The power consumption of the digital part of the on-chip peripherals is given in
Table 52. The power consumption of the analog part of the peripherals (where
applicable) is indicated in each related section of the datasheet.

High-speed external clock generated from a crystal/ceramic resonator
The high-speed external (HSE) clock can be supplied with a 4 to 48 MHz crystal/ceramic
resonator oscillator. All the information given in this paragraph are based on design
simulation results obtained with typical external components specified in Table 57. In the
application, the resonator and the load capacitors have to be placed as close as possible to
the oscillator pins in order to minimize output distortion and startup stabilization time. Refer
to the crystal resonator manufacturer for more details on the resonator characteristics
(frequency, package, accuracy).

1. Guaranteed by characterization results.
2. This is a deviation for an individual part once the initial frequency has been measured.
3. Sampling mode means Low-power run/Low-power sleep modes with Temperature sensor disable.
4. Average period of MSI @48 MHz is compared to a real 48 MHz clock over 28 cycles. It includes frequency tolerance + jitter
of MSI @48 MHz clock.
5. Only accumulated jitter of MSI @48 MHz is extracted over 28 cycles.
For next transition: min. and max. jitter of 2 consecutive frame of 28 cycles of the MSI @48 MHz, for 1000 captures over 28
cycles.
For paired transitions: min. and max. jitter of 2 consecutive frame of 56 cycles of the MSI @48 MHz, for 1000 captures over
56 cycles.
6. Guaranteed by design.

EMC characteristics
Susceptibility tests are performed on a sample basis during device characterization.
Functional EMS (electromagnetic susceptibility)
While a simple application is executed on the device (toggling 2 LEDs through I/O ports).
the device is stressed by two electromagnetic events until a failure occurs. The failure is
indicated by the LEDs:
•
Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until
a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard.
•
FTB: A Burst of Fast Transient voltage (positive and negative) is applied to V and
DD
V
through a 100 pF capacitor, until a functional disturbance occurs. This test is
SS
compliant with the IEC 61000-4-4 standard.
A device reset allows normal operations to be resumed.
The test results are given in Table 70. They are based on the EMS levels and classes
defined in application note AN1709.

Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical
application environment and simplified MCU software. It should be noted that good EMC
performance is highly dependent on the user application and the software in particular.
Therefore it is recommended that the user applies EMC software optimization and
prequalification tests in relation with the EMC level requested for his application.
Software recommendations
The software flowchart must include the management of runaway conditions such as:
•
•
•
Corrupted program counter
Unexpected reset
Critical Data corruption (control registers...)

Prequalification trials
Most of the common failures (unexpected reset and program counter corruption) can be
reproduced by manually forcing a low state on the NRST pin or the Oscillator pins for 1
second.
To complete these trials, ESD stress can be applied directly on the device, over the range of
specification values. When unexpected behavior is detected, the software can be hardened
to prevent unrecoverable errors occurring (see application note AN1015).
Electromagnetic Interference (EMI)
The electromagnetic field emitted by the device are monitored while a simple application is
executed (toggling 2 LEDs through the I/O ports). This emission test is compliant with
IEC 61967-2 standard which specifies the test board and the pin loading.

Electrical sensitivity characteristics
Based on three different tests (ESD, LU) using specific measurement methods, the device is
stressed in order to determine its performance in terms of electrical sensitivity.
Electrostatic discharge (ESD)
Electrostatic discharges (a positive then a negative pulse separated by 1 second) are
applied to the pins of each sample according to each pin combination. The sample size
depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test
conforms to the ANSI/JEDEC standard.

Static latch-up
Electrical characteristics
Two complementary static tests are required on six parts to assess the latch-up
performance:
•
•
A supply overvoltage is applied to each power supply pin.
A current injection is applied to each input, output and configurable I/O pin.
These tests are compliant with EIA/JESD 78A IC latch-up standard.

I/O current injection characteristics
As a general rule, current injection to the I/O pins, due to external voltage below V or
SS
above V
(for standard, 3.3 V-capable I/O pins) should be avoided during normal
DDIOx
product operation. However, in order to give an indication of the robustness of the
microcontroller in cases when abnormal injection accidentally happens, susceptibility tests
are performed on a sample basis during device characterization.
Functional susceptibility to I/O current injection
While a simple application is executed on the device, the device is stressed by injecting
current into the I/O pins programmed in floating input mode. While current is injected into
the I/O pin, one at a time, the device is checked for functional failures.
The failure is indicated by an out of range parameter: ADC error above a certain limit (higher
than 5 LSB TUE), out of conventional limits of induced leakage current on adjacent pins (out
of the -5 µA/+0 µA range) or other functional failure (for example reset occurrence or
oscillator frequency deviation).
The characterization results are given in Table 74.
Negative induced leakage current is caused by negative injection and positive induced
leakage current is caused by positive injection.

6. This value represents the pad leakage of the IO itself. The total product pad leakage is provided by this

7. To sustain a voltage higher than MIN(VDD, VDDA, VDDUSB, VLCD) +0.3 V, the internal Pull-up and Pull-Down
resistors must be disabled.
8. Refer to Ibias in Table 91: OPAMP characteristics for the values of the OPAMP dedicated input leakage

9. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable
PMOS/NMOS. This PMOS/NMOS contribution to the series resistance is minimal (~10% order).
All I/Os are CMOS- and TTL-compliant (no software configuration required). Their
characteristics cover more than the strict CMOS-technology or TTL parameters. The
coverage of these requirements is shown in Figure 37 for standard I/Os, and in Figure 37 for
5 V tolerant I/Os.

1. Guaranteed by design.
2. ADC DC accuracy values are measured after internal calibration.
3. ADC accuracy vs. negative Injection Current: Injecting negative current on any analog input pins should be avoided as this
significantly reduces the accuracy of the conversion being performed on another analog input. It is recommended to add a
Schottky diode (pin to ground) to analog pins which may potentially inject negative current.
4. The I/O analog switch voltage booster is enable when VDDA < 2.4 V (BOOSTEN = 1 in the SYSCFG_CFGR1 when
V
DDA < 2.4 V). It is disable when VDDA ≥ 2.4 V. No oversampling.

1. Refer to Table 81: ADC characteristics for the values of RAIN and CADC
.
2. Cparasitic represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the
pad capacitance (refer to Table 75: I/O static characteristics for the value of the pad capacitance). A high
C
parasitic value will downgrade conversion accuracy. To remedy this, fADC should be reduced.
3. Refer to Table 75: I/O static characteristics for the values of Ilkg
.
General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 25: Power supply
scheme. The 10 nF capacitor should be ceramic (good quality) and it should be placed as
close as possible to the chip.

The I2C interface meets the timings requirements of the I C-bus specification and user
manual rev. 03 for:
•
•
•
Standard-mode (Sm): with a bit rate up to 100 kbit/s
Fast-mode (Fm): with a bit rate up to 400 kbit/s
Fast-mode Plus (Fm+): with a bit rate up to 1 Mbit/s.
The I2C timings requirements are guaranteed by design when the I2C peripheral is properly
configured (refer to RM0432 reference manual).
The SDA and SCL I/O requirements are met with the following restrictions: the SDA and
SCL I/O pins are not “true” open-drain. When configured as open-drain, the PMOS
connected between the I/O pin and V
is disabled, but is still present. Only FT_f I/O pins
DDIOx
support Fm+ low level output current maximum requirement. Refer to Section 6.3.17: I/O
port characteristics for the I2C I/Os characteristics.
All I2C SDA and SCL I/Os embed an analog filter. Refer to Table 99 below for the analog
filter characteristics:

1. All the voltages are measured from the local ground potential.
2. The STM32L4R5xx USB OTG full speed transceiver functionality is ensured down to 2.7 V but not the full
USB full speed electrical characteristics which are degraded in the 2.7-to-3.0 V VDD voltage range.
3. Guaranteed by design.
4. RL is the load connected on the USB OTG full speed drivers.
Note:
When VBUS sensing feature is enabled, PA9 should be left at its default state (floating
input), not as alternate function. A typical 200 μA current consumption of the sensing block
(current to voltage conversion to determine the different sessions) can be observed on PA9
when the feature is enabled.

Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the ordering
information scheme shown in Section 8: Ordering information.
Each temperature range suffix corresponds to a specific guaranteed ambient temperature at
maximum dissipation and, to a specific maximum junction temperature.
As applications do not commonly use the STM32L4Rxxx at maximum dissipation, it is useful
to calculate the exact power consumption and junction temperature to determine which
temperature range will be best suited to the application.

Package information
STM32L4R5xx, STM32L4R7xx and STM32L4R9xx
The following examples show how to calculate the temperature range needed for a given
application.
Example 1: High-performance application
Assuming the following application conditions:
Maximum ambient temperature T
= 82 °C (measured according to JESD51-2),
Amax
I
= 50 mA, V = 3.5 V, maximum 20 I/Os used at the same time in output at low
DDmax
DD
level with I = 8 mA, V = 0.4 V and maximum 8 I/Os used at the same time in output
OL
OL
at low level with I = 20 mA, V = 1.3 V
OL
OL
P
P
= 50 mA × 3.5 V= 175 mW
INTmax
= 20 × 8 mA × 0.4 V + 8 × 20 mA × 1.3 V = 272 mW
IOmax
This gives: P
= 175 mW and P
= 272 mW:
IOmax
INTmax
P
= 175 + 272 = 447 mW
Dmax
Using the values obtained in Table 136 T
is calculated as follows:
Jmax
–
T
For LQFP100, 42 °C/W
= 82 °C + (42 °C/W × 447 mW) = 82 °C + 18.774 °C = 100.774 °C
Jmax
This is within the range of the suffix 6 version parts (–40 < T < 105 °C) see Section 8:
J
Ordering information.
In this case, parts must be ordered at least with the temperature range suffix 6 (see
Section 8: Ordering information).
Note:
With this given P
we can find the T
allowed for a given device temperature range
Amax
Dmax
(order code suffix 6 or 7).
Suffix 6: T
Suffix 3: T
= T
= T
- (42°C/W × 447 mW) = 105-18.774 = 86.226 °C
- (42°C/W × 447 mW) = 130-18.774 = 111.226 °C
Amax
Amax
Jmax
Jmax
Example 2: High-temperature application
Using the same rules, it is possible to address applications that run at high ambient
temperatures with a low dissipation, as long as junction temperature T remains within the
J
specified range.
Assuming the following application conditions:
Maximum ambient temperature T
= 100 °C (measured according to JESD51-2),
Amax
I
= 20 mA, V = 3.5 V, maximum 20 I/Os used at the same time in output at low
DDmax
DD
level with I = 8 mA, V = 0.4 V
OL
OL
P
P
= 20 mA × 3.5 V= 70 mW
INTmax
= 20 × 8 mA × 0.4 V = 64 mW
IOmax
This gives: P
= 70 mW and P
= 64 mW:
IOmax
INTmax
P
= 70 + 64 = 134 mW
Dmax
Thus: P
= 134 mW
Dmax
Using the values obtained in Table 136 T
is calculated as follows:
Jmax
–
T
For LQFP100, 42 °C/W
= 100 °C + (42 °C/W × 134 mW) = 100 °C + 5.628 °C = 105.628 °C
Jmax
This is above the range of the suffix 6 version parts (–40 < T < 105 °C).
