PSoC Functional Overview
The PSoC architecture for this device family, as shown in
Figure 1, consists of three main areas: the Core, the System
Resources, and the CapSense Analog System. A common
versatile bus enables connection between I/O and the analog
system. Each CY8C20x34 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 28 general purpose I/O (GPIO) are also
included. The GPIO provide access to the MCU and analog mux.

Analog Global Bus
The PSoC family consists of many Programmable
System-on-Chips with On-Chip Controller devices. These
devices are designed to replace multiple traditional MCU based
system components with one low cost single chip programmable
component. A PSoC device includes configurable analog and
digital blocks and programmable interconnect. This architecture
enables 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.

The Analog System consists of the CapSense PSoC block and
an internal 1.8 V analog reference. Together they support capacitive sensing of up to 28 inputs.
CapSense Analog 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. Capacitive sensing is configurable on
each GPIO pin. Scanning of enabled CapSense pins is
completed quickly and easily across multiple ports.

Analog Multiplexer System
The Analog Mux Bus connects 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
touch pads
■
Chip-wide mux that enables analog input from any I/O pin
■
Crosspoint connection between any I/O pin combinations

Additional System Resources
System Resources provide additional capability useful to
complete systems. Additional resources include low voltage
detection and power on reset. Brief statements describing the
merits of each system resource follow:
■
The I2C slave or SPI master-slave module provides 50/100/400
kHz communication over two wires. SPI communication over
three or four wires run at speeds of 46.9 kHz to 3 MHz (lower
for a slower system clock).
■
Low voltage detection (LVD) interrupts signal the application of
falling voltage levels, while the advanced POR (Power On
Reset) circuit eliminates the need for a system supervisor.
■
An internal 1.8 V reference provides an absolute reference for
capacitive sensing.
■
The 5 V maximum input, 3 V fixed output, low dropout regulator
(LDO) provides regulation for I/Os. A register controlled bypass
mode enables the user to disable the LDO.
PSoC Device Characteristics
Depending on your PSoC device characteristics, the digital and analog systems can have 16, 8, or 4 digital blocks, and 12, 6, or 4
analog blocks. Table 1 lists the resources available for specific PSoC device groups. The PSoC device covered by this datasheet is

Development Tools
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:
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.
■
Application editor graphical user interface (GUI) for device and
user module configuration and dynamic reconfiguration
■

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.

❐ Up to four full-duplex universal asynchronous receiver/transmitters (UARTs), SPI master and slave, and wireless
PSoC Designer supports the entire library of PSoC 1 devices and
runs on Windows XP, Windows Vista, and Windows 7.
PSoC Designer Software Subsystems
Design Entry
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 ADCs, DACs, amplifiers, and filters. Configure
Document Number: 001-05356 Rev. *P
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 allows you to use more than 100 percent of PSoC's
resources for an application.
Code Generation Tools
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 are
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.
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 allows you to create a trace buffer of registers and memory
locations of interest.
Online Help System
The online help system displays online, context-sensitive help.
Designed for procedural and quick reference, each functional
subsystem has its own context-sensitive help. This system also
provides tutorials and links to FAQs and an online support Forum
to aid the designer.
In-Circuit Emulator
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.
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 by 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 summarized in four steps:
1. Select User Modules.
2. Configure User Modules.
3. Organize and Connect.
4. Generate, Verify, and Debug.
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.
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 8 bits of resolution. The user module parameters permit
you to 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 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
internal operation of the user module 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.
Document Number: 001-05356 Rev. *P
Organize and Connect
You build signal chains at the chip level 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 all on-chip resources.
Generate, Verify, and Debug
When you are ready to test the hardware configuration or move
on 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. The
generated code provides application programming interfaces
(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.
A complete code development environment allows you to
develop and customize your applications in either 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. These include
monitoring address and data bus values, memory locations, and
external signals.

of 25,000 maximum cycles each, or 36 × 4 blocks of 12,500 maximum cycles each (to limit the total number of cycles to 36 × 50,000 and that no single block ever
sees more than 50,000 cycles).
17. The 50,000 cycle flash endurance per block is only guaranteed if the flash is operating within one voltage range. Voltage ranges are 2.4 V to 3.0 V, 3.0 V to 3.6 V

external to that process, and performed in such a way that the process can be resumed.
interrupt service
routine (ISR)
A block of code that normal code execution is diverted to when the M8C receives a hardware
interrupt. Many interrupt sources may each exist with its own priority and individual ISR code
block. Each ISR code block ends with the RETI instruction, returning the device to the point in
the program where it left normal program execution.

M8C
An 8-bit Harvard-architecture microprocessor. The microprocessor coordinates all activity inside
a PSoC by interfacing to the Flash, SRAM, and register space.
master device
A device that controls the timing for data exchanges between two devices. Or when devices are
cascaded in width, the master device is the one that controls the timing for data exchanges
between the cascaded devices and an external interface. The controlled device is called the
slave device.

Glossary
microcontroller
An integrated circuit chip that is designed primarily for control systems and products. In addition
to a CPU, a microcontroller typically includes memory, timing circuits, and IO circuitry. The reason
for this is to permit the realization of a controller with a minimal quantity of chips, thus
achieving maximal possible miniaturization. This in turn, reduces the volume and the cost of
the controller. The microcontroller is normally not used for general-purpose computation as is a
microprocessor.
mixed-signal
The reference to a circuit containing both analog and digital techniques and components.
modulator
A device that imposes a signal on a carrier.
noise
1. A disturbance that affects a signal and that may distort the information carried by the signal.
2. The random variations of one or more characteristics of any entity such as voltage, current, or data.
oscillator
A circuit that may be crystal controlled and is used to generate a clock frequency.
parity
A technique for testing transmitting data. Typically, a binary digit is added to the data to make the
sum of all the digits of the binary data either always even (even parity) or always odd (odd parity).
Phase-locked
loop (PLL)
An electronic circuit that controls an oscillator so that it maintains a constant phase angle relative
to a reference signal.
pinouts
The pin number assignment: the relation between the logical inputs and outputs of the PSoC
device and their physical counterparts in the printed circuit board (PCB) package. Pinouts
involve pin numbers as a link between schematic and PCB design (both being computer generated
files) and may also involve pin names.
port
A group of pins, usually eight.
Power on reset
(POR)
A circuit that forces the PSoC device to reset when the voltage is lower than a pre-set level. This is a type of
hardware reset.
PSoC®
Cypress Semiconductor’s PSoC® is a registered trademark and Programmable System-onChip™ is a trademark of Cypress.
PSoC Designer™ The software for Cypress’ Programmable System-on-Chip technology.
pulse width
An output in the form of duty cycle which varies as a function of the applied measurand
modulator (PWM)
RAM
An acronym for random access memory. A data-storage device from which data can be read out
and new data can be written in.
register
A storage device with a specific capacity, such as a bit or byte.
reset
A means of bringing a system back to a know state. See hardware reset and software reset.
ROM
An acronym for read only memory. A data-storage device from which data can be read out, but
new data cannot be written in.

settling time
The time it takes for an output signal or value to stabilize after the input has changed from one
value to another.
shift register
A memory storage device that sequentially shifts a word either left or right to output a stream of
serial data.
slave device
A device that allows another device to control the timing for data exchanges between two
devices. Or when devices are cascaded in width, the slave device is the one that allows another
device to control the timing of data exchanges between the cascaded devices and an external
interface. The controlling device is called the master device.
SRAM
An acronym for static random access memory. A memory device where you can store and
retrieve data at a high rate of speed. The term static is used because, after a value is loaded into an SRAM cell,
it remains unchanged until it is explicitly altered or until power is removed from the device.
SROM
An acronym for supervisory read only memory. The SROM holds code that is used to boot the
device, calibrate circuitry, and perform Flash operations. The functions of the SROM may be
accessed in normal user code, operating from Flash.
stop bit
A signal following a character or block that prepares the receiving device to receive the next
character or block.
synchronous
1. A signal whose data is not acknowledged or acted upon until the next active edge of a clock signal.
2. A system whose operation is synchronized by a clock signal.
tri-state
A function whose output can adopt three states: 0, 1, and Z (high-impedance). The function does
not drive any value in the Z state and, in many respects, may be considered to be disconnected
from the rest of the circuit, allowing another output to drive the same net.
UART
A UART or universal asynchronous receiver-transmitter translates between parallel bits of data
and serial bits.
user modules
Pre-build, pre-tested hardware/firmware peripheral functions that take care of managing and
configuring the lower level Analog and Digital PSoC Blocks. User Modules also provide high
level API (Application Programming Interface) for the peripheral function.
user space
The bank 0 space of the register map. The registers in this bank are more likely to be modified
during normal program execution and not just during initialization. Registers in bank 1 are most
likely to be modified only during the initialization phase of the program.
VDD
A name for a power net meaning "voltage drain." The most positive power supply signal. Usually
5 V or 3.3 V.
VSS
A name for a power net meaning "voltage source." The most negative power supply signal.
watchdog timer
A timer that must be serviced periodically. If it is not serviced, the CPU resets after a specified
period of time.
