required tuning parameters. SmartSense allows engineers to go
from prototyping to mass production without re-tuning for
manufacturing variations in PCB and/or overlay material
properties.
PSoC Functional Overview
The PSoC family consists of on-chip controller devices, which
are designed to replace multiple traditional microcontroller unit
(MCU)-based components with one, low cost single-chip
SmartSense_EMC
programmable component.
A
PSoC device includes
configurable analog and digital blocks, and programmable
interconnect. This architecture allows the user to create
customized peripheral configurations, to match the requirements
of each individual application. Additionally, a fast CPU, Flash
program memory, SRAM data memory, and configurable I/O are
included in a range of convenient pinouts.
In addition to the SmartSense auto tuning algorithm to remove
manual tuning of CapSense applications, SmartSense_EMC
user module incorporates a unique algorithm to improve
robustness of capacitive sensing algorithm/circuit against high
frequency conducted and radiated noise. Every electronic device
must comply with specific limits for radiated and conducted
external noise and these limits are specified by regulatory bodies
(for example, FCC, CE, U/L and so on). A very good PCB layout
design, power supply design and system design is a mandatory
for a product to pass the conducted and radiated noise tests. An
ideal PCB layout, power supply design or system design is not
often possible because of cost and form factor limitations of the
product. SmartSense_EMC with superior noise immunity is well
suited and handy for such applications to pass radiated and
conducted noise test.
The architecture for this device family, as shown in the Logic
Block Diagram on page 2, consists of three main areas:
■ The Core
■ CapSense Analog System
■ System Resources (including a full-speed USB port).
A common, versatile bus allows connection between I/O and the
analog system.
Figure 1. CapSense System Block Diagram
Each CY8C20XX6A/S PSoC device includes a dedicated
CapSense block that provides sensing and scanning control
circuitry for capacitive sensing applications. Depending on the
PSoC package, up to 36 GPIO are also included. The GPIO
provides access to the MCU and analog mux.

PSoC Core
The PSoC Core is a powerful engine that supports a rich
instruction set. It encompasses SRAM for data storage, an
interrupt controller, sleep and watchdog timers, and IMO and
ILO. The CPU core, called the M8C, is a powerful processor with
speeds up to 24 MHz. The M8C is a 4-MIPS, 8-bit
Harvard-architecture microprocessor.

CapSense System
The analog system contains the capacitive sensing hardware.
Several hardware algorithms are supported. This hardware
performs capacitive sensing and scanning without requiring
external components. The analog system is composed of the
CapSense PSoC block and an internal 1 V or 1.2 V analog
reference, which together support capacitive sensing of up to
33 inputs . Capacitive sensing is configurable on each GPIO
pin. Scanning of enabled CapSense pins are completed quickly
and easily across multiple ports.

communication interface, three 16-bit programmable timers, and
various system resets supported by the M8C.
The Analog Mux Bus can connect to every GPIO pin. Pins are
connected to the bus individually or in any combination. The bus
also connects to the analog system for analysis with the
CapSense block comparator.
These system resources provide additional capability useful to
complete systems. Additional resources include low voltage
detection and power on reset. The merits of each system
resource are listed here:
Switch control logic enables selected pins to precharge
continuously under hardware control. This enables capacitive
measurement for applications such as touch sensing. Other
multiplexer applications include:

■ The I C slave/SPI master-slave module provides
50/100/400 kHz communication over two wires. SPI
communication over three or four wires runs at speeds of
46.9 kHz to 3 MHz (lower for a slower system clock).
■ Complex capacitive sensing interfaces, such as sliders and
touchpads.
■ Low-voltage detection (LVD) interrupts can signal the
application of falling voltage levels, while the advanced
power-on-reset (POR) circuit eliminates the need for a system
supervisor.
■ Chip-wide mux that allows analog input from any I/O pin.
■ Crosspoint connection between any I/O pin combinations.
■ An internal reference provides an absolute reference for
capacitive sensing.

Code Generation Tools
Development Tools
The code generation tools work seamlessly within the
PSoC Designer interface and have been tested with a full range
of debugging tools. You can develop your design in C, assembly,
or a combination of the two.
PSoC Designer™ is the revolutionary integrated design
environment (IDE) that you can use to customize PSoC to meet
your specific application requirements. PSoC Designer software
accelerates system design and time to market. Develop your
applications using a library of precharacterized analog and digital
peripherals (called user modules) in a drag-and-drop design
environment. Then, customize your design by leveraging the
dynamically generated application programming interface (API)
libraries of code. Finally, debug and test your designs with the
integrated debug environment, including in-circuit emulation and
standard software debug features. PSoC Designer includes:
Assemblers. The assemblers allow you to merge assembly
code seamlessly with C code. Link libraries automatically use
absolute addressing or are compiled in relative mode, and linked
with other software modules to get absolute addressing.
C Language Compilers. C language compilers are available
that support the PSoC family of devices. The products allow you
to create complete C programs for the PSoC family devices. The
optimizing C compilers provide all of the features of C, tailored
to the PSoC architecture. They come complete with embedded
libraries providing port and bus operations, standard keypad and
display support, and extended math functionality.
■ Application editor graphical user interface (GUI) for device and
user module configuration and dynamic reconfiguration
■ Extensive user module catalog
■ Integrated source-code editor (C and assembly)
■ Free C compiler with no size restrictions or time limits
■ Built-in debugger
Debugger
PSoC Designer has a debug environment that provides
hardware in-circuit emulation, allowing you to test the program in
a physical system while providing an internal view of the PSoC
device. Debugger commands allow you to read and program and
read and write data memory, and read and write I/O registers.
You can read and write CPU registers, set and clear breakpoints,
and provide program run, halt, and step control. The debugger
also lets you to create a trace buffer of registers and memory
locations of interest.

runs on Windows XP, Windows Vista, and Windows 7.
PSoC Designer Software Subsystems
Design Entry
In-Circuit Emulator
In the chip-level view, choose a base device to work with. Then
select different onboard analog and digital components that use
the PSoC blocks, which are called user modules. Examples of
user modules are analog-to-digital converters (ADCs),
digital-to-analog converters (DACs), amplifiers, and filters.
Configure the user modules for your chosen application and
connect them to each other and to the proper pins. Then
generate your project. This prepopulates your project with APIs
and libraries that you can use to program your application.
A
low-cost, high-functionality in-circuit emulator (ICE) is
available for development support. This hardware can program
single devices.
The emulator consists of a base unit that connects to the PC
using a USB port. The base unit is universal and operates with
all PSoC devices. Emulation pods for each device family are
available separately. The emulation pod takes the place of the
PSoC device in the target board and performs full-speed
(24 MHz) operation.
The tool also supports easy development of multiple
configurations and dynamic reconfiguration. Dynamic
reconfiguration makes it possible to change configurations at run
time. In essence, this lets you to use more than 100 percent of
PSoC’s resources for an application.

internal operation of the user module and provide performance
specifications. Each datasheet describes the use of each user
module parameter, and other information that you may need to
successfully implement your design.
Designing with PSoC Designer
The development process for the PSoC device differs from that
of a traditional fixed-function microprocessor. The configurable
analog and digital hardware blocks give the PSoC architecture a
unique flexibility that pays dividends in managing specification
change during development and lowering inventory costs. These
configurable resources, called PSoC blocks, have the ability to
implement a wide variety of user-selectable functions. The PSoC
development process is:
Organize and Connect
Build signal chains at the chip level by interconnecting user
modules to each other and the I/O pins. Perform the selection,
configuration, and routing so that you have complete control over
all on-chip resources.
1. Select user modules.
Generate, Verify, and Debug
2. Configure user modules.
3. Organize and connect.
4. Generate, verify, and debug.
When you are ready to test the hardware configuration or move
on to developing code for the project, perform the “Generate
Configuration Files” step. This causes PSoC Designer to
generate source code that automatically configures the device to
your specification and provides the software for the system. The
generated code provides APIs with high-level functions to control
and respond to hardware events at run time, and interrupt
service routines that you can adapt as needed.
Select User Modules
PSoC Designer provides a library of prebuilt, pretested hardware
peripheral components called “user modules”. User modules
make selecting and implementing peripheral devices, both
analog and digital, simple.
A complete code development environment lets you to develop
and customize your applications in C, assembly language, or
both.
Configure User Modules
Each user module that you select establishes the basic register
settings that implement the selected function. They also provide
parameters and properties that allow you to tailor their precise
configuration to your particular application. For example, a PWM
User Module configures one or more digital PSoC blocks, one
for each eight bits of resolution. Using these parameters, you can
establish the pulse width and duty cycle. Configure the
parameters and properties to correspond to your chosen
application. Enter values directly or by selecting values from
drop-down menus. All of the user modules are documented in
datasheets that may be viewed directly in PSoC Designer or on
the Cypress website. These user module datasheets explain the
The last step in the development process takes place inside
PSoC Designer’s Debugger (accessed by clicking the Connect
icon). PSoC Designer downloads the HEX image to the ICE
where it runs at full-speed. PSoC Designer debugging
capabilities rival those of systems costing many times more. In
addition to traditional single-step, run-to-breakpoint, and
watch-variable features, the debug interface provides a large
trace buffer. It lets you to define complex breakpoint events that
include monitoring address and data bus values, memory
locations, and external signals.

resistive low for 512 sleep clock cycles and both the pins transition to high impedance state. On reset, after XRES de-asserts, the SDA and the SCL lines drive
resistive low for 8 sleep clock cycles and transition to high impedance state. Hence, during power-up or reset event, P1[1] and P1[0] may disturb the I2C bus. Use
alternate pins if you encounter issues.

Notes
7. 20 GPIOs = 17 pins for capacitive sensing + 2 pins for I2C + 1 pin for modulation capacitor.
8. The center pad (CP) on the QFN package must be connected to ground (V ) for best mechanical, thermal, and electrical performance. If not connected to ground,
SS
it must be electrically floated and not connected to any other signal.
9. On power-up, the SDA(P1[0]) drives a strong high for 256 sleep clock cycles and drives resistive low for the next 256 sleep clock cycles. The SCL(P1[1]) line drives
resistive low for 512 sleep clock cycles and both the pins transition to high impedance state. On reset, after XRES de-asserts, the SDA and the SCL lines drive
resistive low for 8 sleep clock cycles and transition to high impedance state. Hence, during power-up or reset event, P1[1] and P1[0] may disturb the I2C bus. Use
alternate pins if you encounter issues.
10. Alternate SPI clock.

26. 34 GPIOs = 31 pins for capacitive sensing + 2 pins for I2C + 1 pin for modulation capacitor.
27. On power-up, the SDA(P1[0]) drives a strong high for 256 sleep clock cycles and drives resistive low for the next 256 sleep clock cycles. The SCL(P1[1]) line drives
resistive low for 512 sleep clock cycles and both the pins transition to high impedance state. On reset, after XRES de-asserts, the SDA and the SCL lines drive
resistive low for 8 sleep clock cycles and transition to high impedance state. Hence, during power-up or reset event, P1[1] and P1[0] may disturb the I2C bus. Use

Notes
44. When VDD remains in the range from 1.71 V to 1.9 V for more than 50 µs, the slew rate when moving from the 1.71 V to 1.9 V range to greater than 2 V must be
slower than 1 V/500 µs to avoid triggering POR. The only other restriction on slew rates for any other voltage range or transition is the SRPOWER_UP parameter.
45. If powering down in standby sleep mode, to properly detect and recover from a VDD brown out condition any of the following actions must be taken:
a.Bring the device out of sleep before powering down.
b.Assure that VDD falls below 100 mV before powering back up.
c.Set the No Buzz bit in the OSC_CR0 register to keep the voltage monitoring circuit powered during sleep.
d.Increase the buzz rate to assure that the falling edge of VDD is captured. The rate is configured through the PSSDC bits in the SLP_CFG register.
For the referenced registers, refer to the CY8C20X36 Technical Reference Manual. In deep sleep mode, additional low power voltage monitoring circuitry allows
V
DD brown out conditions to be detected for edge rates slower than 1V/ms.
46. For USB mode, the VDD supply for bus-powered application should be limited to 4.35 V–5.35 V. For self-powered application, VDD should be 3.15 V–3.45 V.
47. For proper CapSense block functionality, if the drop in VDD exceeds 5% of the base VDD, the rate at which VDD drops should not exceed 200 mV/s. Base VDD can
be between 1.8 V and 5.5 V.
48. Errata: When the device is put to sleep in Standby or I2C_USB Mode and the bandgap circuit is refreshed less frequently than every 8 ms (default), the device may
not come out of sleep when a sleep-ending input is received. For more information, see the “Errata” on page 45.
49. Errata: The I2C block exhibits occasional data and bus corruption errors when the I2C master initiates transactions while the device is in or out of transition of sleep
mode. For more information, see the “Errata” on page 45.
50. Errata: When programmable timer 0 is used in “one-shot” mode by setting bit 1 of register 0,B0h (PT0_CFG), and the timer interrupt is used to wake the device from
sleep, the interrupt service routine (ISR) may be executed twice. For more information, see the “Errata” on page 46.
51. Errata: When in sleep mode, if a GPIO interrupt happens simultaneously with a Timer0 or Sleep Timer interrupt, the GPIO interrupt may be missed, and the
corresponding GPIO ISR not run. For more information, see the “Errata” on page 46.
52. Errata: If an interrupt is posted a short time (within 2.5 CPU cycles) before firmware commands the device to sleep, the interrupt will be missed. For more information,
see the “Errata” on page 47.
53. Errata: Device wakes up from sleep when an analog interrupt is trigger. For more information, see the “Errata” on page 47.

Note
62. A Fast-Mode I2C-bus device can be used in a standard mode I2C-bus system, but the requirement tSU;DAT 250 ns must then be met. This automatically be the
case if the device does not stretch the LOW period of the SCL signal. If such device does stretch the LOW period of the SCL signal, it must output the next data bit
to the SDA line trmax + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-Mode I2C-bus specification) before the SCL line is released.

Numeric Naming
Hexadecimal numbers are represented with all letters in uppercase with an appended lowercase ‘h’ (for example, ‘14h’ or ‘3Ah’).
Hexadecimal numbers may also be represented by a ‘0x’ prefix, the C coding convention. Binary numbers have an appended
lowercase ‘b’ (for example, 01010100b’ or ‘01000011b’). Numbers not indicated by an ‘h’, ‘b’, or 0x are decimal.
Glossary
Crosspoint connection
Differential non-linearity
Connection between any GPIO combination via analog multiplexer bus.
Ideally, any two adjacent digital codes correspond to output analog voltages that are exactly
one LSB apart. Differential non-linearity is a measure of the worst case deviation from the
ideal 1 LSB step.
Hold time
Hold time is the time following a clock event during which the data input to a latch or flip-flop
must remain stable in order to guarantee that the latched data is correct.
2
I C
It is a serial multi-master bus used to connect low speed peripherals to MCU.
Integral nonlinearity
It is a term describing the maximum deviation between the ideal output of a DAC/ADC and
the actual output level.
Latch-up current
Current at which the latch-up test is conducted according to JESD78 standard (at 125
degree Celsius)
Power supply rejection ratio (PSRR)
The PSRR is defined as the ratio of the change in supply voltage to the corresponding
change in output voltage of the device.
Scan
The conversion of all sensor capacitances to digital values.
Setup time
Period required to prepare a device, machine, process, or system for it to be ready to
function.
Signal-to-noise ratio
SPI
The ratio between a capacitive finger signal and system noise.
Serial peripheral interface is a synchronous serial data link standard.

Errata
®
This section describes the errata for the PSoC CY8C20x36A/46A/66A/96A/46AS/66AS/36H/46H families. Details include errata
trigger conditions, scope of impact, available workarounds, and silicon revision applicability. Contact your local Cypress Sales Repre-
sentative if you have questions.
Qualification Status
Product Status: Production released.
Errata Summary
The following Errata items apply to CY8C20x36A/46A/66A/96A/46AS/66AS/36H/46H families.
1. Wakeup from sleep may intermittently fail
■ Problem Definition
When the device is put to sleep in Standby or I2C_USB Mode and the bandgap circuit is refreshed less frequently than every 8 ms
(default), the device may not come out of sleep when a sleep-ending input is received.
■ Parameters Affected
None
■ Trigger Condition(S)
By default, when the device is in the Standby or I2C_USB sleep modes, the bandgap circuit is powered-up approximately every 8
ms to facilitate detection of POR or LVD events. This interval can be lengthened or the periodic power-up disabled to reduce sleep
current by setting the ALT_BUZZ bits in the SLP_CFG2 register or the Disable Buzz bit in the OSC_CR0 register respectively. If
the bandgap circuit refresh interval is set longer than the default 8 ms, the device may fail to wakeup from sleep and enter a locked
up state that can only be recovered by Watchdog Reset, XRES, or POR.
■ Scope of Impact
The trigger conditions outlined above may cause the device to never wakeup.
■ Workaround
Prior to entering Standby or I2C_USB sleep modes, do not lengthen or disable the bandgap refresh interval by manipulating the
ALT_BUZZ bits in the SLP_CFG2 register or the Disable Buzz bit in the OSC_CR0 register respectively.
■ Fix Status
This issue will not be corrected in the next silicon revision.
2. I2C Errors
■ Problem Definition
2
2
The I C block exhibits occasional data and bus corruption errors when the I C master initiates transactions while the device is
transitioning in to or out of sleep mode.
■ Parameters Affected
2
2
2
Affects reliability of I C communication to device, and between I C master and third party I C slaves.
■ Trigger Condition(S)
Triggered by transitions into and out of the device’s sleep mode.
■ Scope of Impact
2
Data errors result in incorrect data reported to the I C master, or incorrect data received from the master by the device. Bus
2
2
corruption errors can corrupt data in transactions between the I C master and third party I C slaves.
■ Workaround
2
Firmware workarounds are available in firmware. Generally the workaround consists of disconnecting the I C block from the bus
2
prior to going to sleep modes. I C transactions during sleep are supported by a protocol in which the master wakes the device prior
2
to the I C transaction.
■ Fix Status
To be fixed in future silicon.

CY8C20XX6A/S
■ Changes
None
3. DoubleTimer0 ISR
■ Problem Definition
When programmable timer 0 is used in “one-shot” mode by setting bit 1 of register 0,B0h (PT0_CFG), and the timer interrupt is
used to wake the device from sleep, the interrupt service routine (ISR) may be executed twice.
■ Parameters Affected
No datasheet parameters are affected.
■ Trigger Condition(S)
Triggered by enabling one-shot mode in the timer, and using the timer to wake from sleep mode.
■ Scope of Impact
The ISR may be executed twice.
■ Workaround
In the ISR, firmware should clear the one-shot bit with a statement such as “and reg[B0h], FDh”
■ Fix Status
Will not be fixed
■ Changes
None
4. Missed GPIO Interrupt
■ Problem Definition
When in sleep mode, if a GPIO interrupt happens simultaneously with a Timer0 or Sleep Timer interrupt, the GPIO interrupt may
be missed, and the corresponding GPIO ISR not run.
■ Parameters Affected
No datasheet parameters are affected.
■ Trigger Condition(S)
Triggered by enabling sleep mode, then having GPIO interrupt occur simultaneously with a Timer 0 or Sleep Timer interrupt.
■ Scope of Impact
The GPIO interrupt service routine will not be run.
■ Workaround
The system should be architected such that a missed GPIO interrupt may be detected. For example, if a GPIO is used to wake
the system to perform some function, the system should detect if the function is not performed, and re-issue the GPIO interrupt.
Alternatively, if a GPIO interrupt is required to wake the system, then firmware should disable the Sleep Timer and Timer0.
Alternatively, the ISR’s for Sleep Timer and Timer0 should manually check the state of the GPIO to determine if the host system
has attempted to generate a GPIO interrupt.
