PSoC® Functional Overview
Figure 1. CapSense System Block Diagram
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
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.

Each CY8C20x36A/46A/66A/96A 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.

CSCLK
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[2]. Capacitive sensing is configurable on each GPIO
pin. Scanning of enabled CapSense pins are completed quickly
and easily across multiple ports.
SmartSense™
SmartSense is an innovative solution from Cypress that removes
manual tuning of CapSense applications. This solution is easy to
use and provides a robust noise immunity. It is the only autotuning solution that establishes, monitors, and maintains all
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.
IMO
CapSense
Clock Select
Oscillator
Analog Multiplexer System
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.
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:
■
Complex capacitive sensing interfaces, such as sliders and
touchpads.
■
Chip-wide mux that allows analog input from any I/O pin.
■
Crosspoint connection between any I/O pin combinations.
Note
2. 36 GPIOs = 33 pins for capacitive sensing+2 pins for I2C + 1 pin for modulator capacitor.

Additional System Resources
System resources provide additional capability, such as
configurable USB and I2C slave, SPI master/slave
communication interface, three 16-bit programmable timers, and
various system resets supported by the M8C.
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:
■
The I2C 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).
■
The I2C hardware address recognition feature reduces the
already low power consumption by eliminating the need for
CPU intervention until a packet addressed to the target device
is received.
■
■
The I2C enhanced slave interface appears as a 32-byte RAM
buffer to the external I2C master. Using a simple predefined
protocol, the master controls the read and write pointers into
the RAM. When this method is enabled, the slave does not stall
the bus when receiving data bytes in active mode. For usage
details, refer to the application note I2C Enhanced Slave
Operation - AN56007.
Low-voltage detection (LVD) interrupts can signal the
application of falling voltage levels, while the advanced poweron-reset (POR) circuit eliminates the need for a system
supervisor.
■
An internal reference provides an absolute reference for
capacitive sensing.
■
A register-controlled bypass mode allows the user to disable
the LDO regulator.

Designing with PSoC Designer
Organize and Connect
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 by lowering inventory costs.
You build signal chains by interconnecting user modules to each
other and the I/O pins. You perform the selection, configuration,
and routing so that you have complete control over the use of all
on-chip resources.
These configurable resources, called PSoC blocks, have the
ability to implement a wide variety of user-selectable functions.
The PSoC development process is summarized in the following
four steps:
1. Select components
2. Configure components
3. Organize and connect
4. Generate, verify, and debug
When you are ready to test the hardware configuration or move
to developing code for the project, you 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.
Based on your design, software is generated. Application
programming interfaces (APIs) are provided 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 Components
A complete code development environment allows you to
develop and customize your applications in C, assembly
language, or both. The last step in the development process
takes place inside PSoC Designer’s Debugger (access 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 and allows you to define complex breakpoint events
that include monitoring address and data bus values, memory
locations and external signals.
PSoC Designer provides a library of prebuilt, pretested hardware
peripheral components. These components are called user
modules. User modules make selecting and implementing
peripheral devices simple, and come in analog, digital, and
programmable system-on-chip varieties.
Configure Components
Each of the components 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 Timer
User Module configures one digital PSoC block. The user
module parameters permit you to establish the period, mode,
and timer clock. Configure the parameters and properties to
correspond to your chosen application. Enter values directly or
by selecting values from drop-down menus.
Generate, Verify, and Debug
User modules are documented in datasheets that are viewed
directly in PSoC Designer. These datasheets explain the internal
operation of the component and provide performance
specifications. Each datasheet describes the use of each user
module parameter and other information you may need to
successfully implement your design.

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

8. The center pad (CP) on the QFN package must be connected to ground (VSS) for best mechanical, thermal, and electrical performance. If not connected to ground,
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.

21. 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.
22. The center pad (CP) on the QFN package must be connected to ground (VSS) for best mechanical, thermal, and electrical performance. If not connected to ground,
it must be electrically floated and not connected to any other signal

Notes
31. When VDD remains in the range from 1.71 V to 1.9 V for more than 50 µsec, 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 usec to avoid triggering POR. The only other restriction on slew rates for any other voltage range or transition is the SRPOWER_UP parameter.
32. 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
VDD brown out conditions to be detected for edge rates slower than 1V/ms.
33. AFor USB mode, the VDD supply for bus-powered application should be limited to 4.35V-5.35V. For self-powered application, VDD should be 3.15 V-3.45 V.
34. 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

Figure 15. Definition for Timing for Fast/Standard Mode on the I2C Bus
Note
41. 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.

Development Tool Selection
Software
PSoC Designer™
At the core of the PSoC development software suite is PSoC
Designer, used to generate PSoC firmware applications. PSoC
Designer is a Microsoft® Windows-based, integrated development environment for the Programmable System-on-Chip
(PSoC) devices. The PSoC Designer IDE and application runs
on Windows XP and Windows Vista.
This system provides design database management by project,
an integrated debugger with In-Circuit Emulator, in-system
programming support, and built-in support for third-party assemblers and C compilers. PSoC Designer also supports C language
compilers developed specifically for the devices in the PSoC
family. PSoC Designer is available free of charge at
http://www.cypress.com/psocdesigner and includes a free C
compiler.
PSoC Designer Software Subsystems
You choose a base device to work with and then select different
onboard analog and digital components called user modules that
use the PSoC blocks. Examples of user modules are ADCs,
DACs, Amplifiers, and Filters. You configure the user modules
for your chosen application and connect them to each other and
to the proper pins. Then you generate your project. This prepopulates your project with APIs and libraries that you can use to
program your application.
The tool also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic reconfiguration
allows for changing configurations at run time. Code Generation
Tools PSoC Designer supports multiple third-party C compilers
and assemblers. The code generation tools work seamlessly
within the PSoC Designer interface and have been tested with a
full range of debugging tools. The choice is yours.
Assemblers. The assemblers allow assembly code to be
merged 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 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.
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 the designer to read and
program and read and write data memory, read and write I/O
registers, read and write CPU registers, set and clear breakpoints, and provide program run, halt, and step control. The
debugger also allows the designer to create a trace buffer of
registers and memory locations of interest.
Document Number: 001-54459 Rev. *E
In-Circuit Emulator
A low cost, high functionality In-Circuit Emulator (ICE) is
available for development support. This hardware has the
capability to program single devices. The emulator consists of a
base unit that connects to the PC by way of 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 (24MHz) operation.
Standard Cypress PSoC IDE tools are available for debugging
the CY8C20x36A/46A/66A/96A family of parts. However, the
additional trace length and a minimal ground plane in the FlexPod can create noise problems that make it difficult to debug the
design. A custom bonded On-Chip Debug (OCD) device is
available in a 48-pin QFN package. The OCD device is recommended for debugging designs that have high current and/or
high analog accuracy requirements. The QFN package is
compact and is connected to the ICE through a high density
connector.
PSoC Programmer
PSoC Programmer is flexible enough and is used on the bench
in development and is also suitable for factory programming.
PSoC Programmer works either as a standalone programming
application or operates directly from PSoC Designer. PSoC
Programmer software is compatible with both PSoC ICE Cube
In-Circuit Emulator and PSoC MiniProg. PSoC programmer is
available free of cost at
http://www.cypress.com/psocprogrammer..

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
Connection between any GPIO combination via analog multiplexer bus.
Differential non-linearity
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 flipflop must remain stable in order to guarantee that the latched data is correct.
I2C
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
The ratio between a capacitive finger signal and system noise.
SPI
Serial peripheral interface is a synchronous serial data link standard.
