Use a simple LC filter (1.6nH and 1.8pF in parallel to ground) to pass ETSI conducted requirements below 1GHz
in restricted bands. For radiated measurements low antenna gain for these frequencies (depending on antenna
design) can achieve the same attenuation of these low frequency components (see EM reference design).

BLOCK DESCRIPTIONS
CPU and Memory
The 8051 CPU core is a single-cycle 8051-compatible core. It has three different memory access busses (SFR,
DATA, and CODE/XDATA), a debug interface, and an 15-input extended interrupt unit.
The memory arbiter is at the heart of the system, as it connects the CPU and DMA controller with the physical
memories and all peripherals through the SFR bus. The memory arbiter has four memory-access points, access
of which can map to one of three physical memories: an SRAM, flash memory, and XREG/SFR registers. It is
responsible for performing arbitration and sequencing between simultaneous memory accesses to the same
physical memory.
The SFR bus is drawn conceptually in 图 7 as a common bus that connects all hardware peripherals to the
memory arbiter. The SFR bus in the block diagram also provides access to the radio registers in the radio
register bank, even though these are indeed mapped into XDATA memory space.
The 1-KB SRAM maps to the DATA memory space and to parts of the XDATA memory spaces.
The 18-KB/32-KB flash block provides in-circuit programmable non-volatile program memory for the device,
and maps into the CODE and XDATA memory spaces.
Peripherals
Writing to the flash block is performed through a flash controller that allows page-wise erasure and 4-bytewise
programming. See User Guide for details on the flash controller.
A versatile two-channel DMA controller is available in the system, accesses memory using the XDATA memory
space, and thus has access to all physical memories. Each channel (trigger, priority, transfer mode, addressing
mode, source and destination pointers, and transfer count) is configured with DMA descriptors that can be
located anywhere in memory. Many of the hardware peripherals (AES core, flash controller, USART, timers, etc.)
can be used with the DMA controller for efficient operation by performing data transfers between a single SFR or
XREG address and flash/SRAM.
The interrupt controller services a total of 17 interrupt sources, divided into six interrupt groups, each of which
is associated with one of four interrupt priorities. Any interrupt service request is serviced also when the device is
in idle mode by going back to active mode. Some interrupts can also wake up the device from sleep mode (when
in sleep mode, the device is in low-power mode PM1, PM2 or PM3).
The debug interface implements a proprietary two-wire serial interface that is used for in-circuit debugging.
Through this debug interface, it is possible to perform an erasure of the entire flash memory, control which
oscillators are enabled, stop and start execution of the user program, execute supplied instructions on the 8051
core, set code breakpoints, and single-step through instructions in the code. Using these techniques, it is
possible to perform in-circuit debugging and external flash programming elegantly.
The I/O controller is responsible for all general-purpose I/O pins. The CPU can configure whether peripheral
modules control certain pins or whether they are under software control, and if so, whether each pin is configured
as an input or output and if a pullup or pulldown resistor in the pad is connected. Each peripheral that connects
to the I/O pins can choose between several different I/O pin locations to ensure flexibility in various applications.
The sleep timer is an ultralow-power timer that can use either an external 32.768-kHz XOSC or an internal
32.753-kHz RC oscillator. The sleep timer runs continuously in all operating modes. Typical applications of this
timer are as a real-time counter or as a wake-up timer to get out of power modes 1 or 2.
A built-in watchdog timer allows the CC2545 to reset itself if the firmware hangs. When enabled by software,
the watchdog timer must be cleared periodically; otherwise, it resets the device when it times out.
Timer 1 is a 16-bit timer with timer/counter/PWM functionality. It has a programmable prescaler, a 16-bit period
value, and five individually programmable counter/capture channels, each with a 16-bit compare value. Each of
the counter/capture channels can be used as a PWM output or to capture the timing of edges on input signals. It
can also be configured in IR generation mode, where it counts timer 3 periods and the output is ANDed with the
output of timer 3 to generate modulated consumer IR signals with minimal CPU interaction.

ZHCSAA7A –JUNE 2012–REVISED AUGUST 2012

Timer 2 is a 40-bit timer used by the Radio. It has a 16-bit counter with a configurable timer period and a 24-bit
overflow counter that can be used to keep track of the number of periods that have transpired. A 40-bit capture
register is also used to record the exact time at which a start-of-frame delimiter is received/transmitted or the
exact time at which a packet ends. There are two 16-bit timer-compare registers and two 24-bit overflow-
compare registers that can be used to give exact timing for start of RX or TX to the radio or general interrupts.
Timer 3 and timer 4 are 8-bit timers with timer/counter/PWM functionality. They have a programmable prescaler,
an 8-bit period value, and one programmable counter channel with an 8-bit compare value. Each of the counter
channels can be used as PWM output.
USART 0 is configurable as either an SPI master/slave or a UART. It provides double buffering on both RX and
TX and hardware flow control and is thus well suited to high-throughput full-duplex applications. The USART has
its own high-precision baud-rate generator, thus leaving the ordinary timers free for other uses. When configured
as SPI slaves, the USART samples the input signal using SCK directly instead of using some oversampling
scheme, and are thus well-suited for high data rates.
I2C module provides a digital peripheral connection with two pins and supports both master and slave operation.
The AES encryption/decryption core allows the user to encrypt and decrypt data using the AES algorithm with
128-bit keys. The AES core also supports ECB, CBC, CFB, OFB, CTR, and CBC-MAC, as well as hardware
support for CCM.
The ultralow power analog comparator enables applications to wake up from PM2 or PM3 based on an analog
signal. Both inputs are brought out to pins; the reference voltage must be provided externally. The comparator
output is mapped into the digital I/O port and can be treated by the MCU as a regular digital input.

A series resistor may be used to comply with ESR requirement.
On-Chip 1.8-V Voltage Regulator Decoupling
The 1.8-V on-chip voltage regulator supplies the 1.8-V digital logic. This regulator requires a decoupling capacitor
(C421) for stable operation.
Power-Supply Decoupling and Filtering
Proper power-supply decoupling must be used for optimum performance. The placement and size of the
decoupling capacitors and the power supply filtering are very important to achieve the best performance in an
application. TI provides a compact reference design that should be followed very closely.
