which are called user modules. Digital peripheral configurations
include those listed.
PSoC Functional Overview
The PSoC family consists of many devices with on-chip
controllers. These devices are designed to replace multiple
■ PWMs (8- to 32-bit)
traditional
microcontroller
unit
(MCU)-based
system
■ PWMs with dead band (8- to 24-bit)
■ Counters (8- to 32-bit)
components with one, low-cost single-chip programmable
component. A PSoC device includes configurable blocks of
analog and digital logic, and programmable interconnect. This
architecture makes it possible for you to create customized
peripheral configurations, to match the requirements of each
individual application. Additionally, a fast central processing unit
(CPU), flash program memory, SRAM data memory, and
configurable I/O are included in a range of convenient pinouts.
■ Timers (8- to 32-bit)
■ Full or half-duplex 8-bit UART with selectable parity
■ SPI master and slave
■ I2C master, slave, or multi-master (implemented in a dedicated
I2C block)
The PSoC architecture, as illustrated in the Logic Block Diagram
on page 1, comprises of four main areas: the core, the system
resources, the digital system, and the analog system. Configu-
rable global bus resources allow all the device resources to be
combined into a complete custom system. Each CY8C21x34
PSoC device includes four digital blocks and four analog blocks.
Depending on the PSoC package, up to 24 GPIOs are also
included. The GPIOs provide access to the global digital and
analog interconnects.
■ Cyclical redundancy checker/generator (16-bit)
■ Infrared Data Association (IrDA)
■ PRS generators (8- to 32-bit)
The digital blocks can be connected to any GPIO through a
series of global buses that can route any signal to any pin. The
buses also allow for signal multiplexing and for performing logic
operations. This configurability frees your designs from the
constraints of a fixed peripheral controller.
The 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 an internal
main oscillator (IMO) and internal low-speed oscillator (ILO). The
CPU core, called the M8C, is a powerful processor with speeds
up to 12 MHz. The M8C is a two-million instructions per second
(MIPS) 8-bit Harvard-architecture microprocessor.

System resources provide additional capability, such as digital
clocks for increased flexibility, I2C functionality for implementing
an I2C master, slave, or multi-master, an internal voltage
reference that provides an absolute value of 1.3 V to a number
of PSoC subsystems, and various system resets supported by
the M8C.

optimum choice of system resources for your application. Family
resources are shown in Table 1 on page 5.
The digital system is composed of four digital PSoC blocks. Each
block is an 8-bit resource that can be used alone or combined
with other blocks to form 8-, 16-, 24-, and 32-bit peripherals,

The Analog Multiplexer System
The Analog System
The analog mux bus can connect to every GPIO pin. Pins can
be connected to the bus individually or in any combination. The
bus also connects to the analog system for analysis with
comparators and ADCs. An additional 8:1 analog input
multiplexer provides a second path to bring Port 0 pins to the
analog array.
The analog system is composed of four configurable blocks,
allowing the creation of complex analog signal flows. Analog
peripherals are very flexible and can be customized to support
specific application requirements. Some of the common PSoC
analog functions for this device (most available as user modules)
are listed.
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:
■ ADCs (single or dual, with up to 10-bit resolution)
■ Pin-to-pin comparator
■ Single-ended comparators (up to two) with absolute (1.3 V)
reference or 8-bit DAC reference
■ Track pad, finger sensing.
■ 1.3 V reference (as a system resource)
■ Chip-wide mux that allows analog input from any I/O pin.
■ Crosspoint connection between any I/O pin combination.
In most PSoC devices, analog blocks are provided in columns of
three, which includes one continuous time (CT) and two switched
capacitor (SC) blocks. The CY8C21x34 devices provide limited
functionality type ‘E’ analog blocks. Each column contains one
CT type ‘E’ block and one SC type ‘E’ block. Refer to the PSoC
Programmable System-on-Chip Technical Reference Manual for
detailed information on the CY8C21x34’s type ‘E’ analog blocks.
Additional System Resources
System resources, some of which have been previously listed,
provide additional capability useful for complete systems. Brief
statements describing the merits of each system resource are
presented.

■ Digital clock dividers provide three customizable clock
frequencies for use in applications. The clocks can be routed
to both the digital and analog systems. Additional clocks can
be generated using digital PSoC blocks as clock dividers.

Development Tools
PSoC Designer™ is the revolutionary integrated design
Code Generation Tools
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 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.
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.
■ 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 allows you to create a trace buffer of registers and memory
locations of interest.
■ In-circuit emulation
■ Built-in support for communication interfaces:
❐ Hardware and software I2C slaves and masters
❐ Full-speed USB 2.0
❐ 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.
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.
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
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.
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.
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.

CY8C21334, CY8C21534
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.
provide performance specifications. Each datasheet describes
the use of each user module parameter, and other information
you may need to successfully implement your design.
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.
The PSoC development process can be summarized in the
following four steps:
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, 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.
Select Components
PSoC Designer provides a library of pre-built, pre-tested
hardware peripheral components called "user modules." User
modules make selecting and implementing peripheral devices,
both analog and digital, simple.
A complete code development environment allows you to
develop and customize your applications in C, assembly
language, or both.
Configure Components
Each of the User Modules 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
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 capabil-
ities rival those of systems costing many times more. In addition
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 corre-
spond 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
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.

Register Mapping Tables
This section lists the registers of the automotive CY8C21x34
PSoC device. For detailed register information, reference the
PSoC Technical Reference Manual.
The PSoC device has a total register address space of 512
bytes. The register space is referred to as I/O space and is
divided into two banks. The XIO bit in the Flag register (CPU_F)
determines which bank the user is currently in. When the XIO bit
is set the user is in Bank 1.
The register conventions specific to this section are listed in
Table 4.

Glossary (continued)
external reset
(XRES)
An active high signal that is driven into the PSoC device. It causes all operation of the CPU and blocks to stop
and return to a pre-defined state.
flash
An electrically programmable and erasable, non-volatile technology that provides you the programmability and
data storage of EPROMs, plus in-system erasability. Non-volatile means that the data is retained when power is
off.
flash block
The smallest amount of flash ROM space that may be programmed at one time and the smallest amount of flash
space that may be protected.
frequency
gain
The number of cycles or events per unit of time, for a periodic function.
The ratio of output current, voltage, or power to input current, voltage, or power, respectively. Gain is usually
expressed in dB.
I2C
A two-wire serial computer bus by Phillips Semiconductors (now NXP Semiconductors). It is used to connect
low-speed peripherals in an embedded system. The original system was created in the early 1980s as a battery
control interface, but it was later used as a simple internal bus system for building control electronics. I2C uses
only two bi-directional pins, clock and data, both running at the VDD supply voltage and pulled high with resistors.
The bus operates up to100 kbits/second in standard mode and 400 kbits/second in fast mode.
ICE
The in-circuit emulator that allows you to test the project in a hardware environment, while viewing the debugging
device activity in a software environment (PSoC Designer).
input/output (I/O) A device that introduces data into or extracts data from a system.
interrupt
A suspension of a process, such as the execution of a computer program, caused by an event external to that
process, and performed in such a way that the process can be resumed.
interrupt service A block of code that normal code execution is diverted to when the CPU receives a hardware interrupt. Many
routine (ISR)
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.
jitter
1. A misplacement of the timing of a transition from its ideal position. A typical form of corruption that occurs on
serial data streams.
2. The abrupt and unwanted variations of one or more signal characteristics, such as the interval between
successive pulses, the amplitude of successive cycles, or the frequency or phase of successive cycles.
low voltage detect A circuit that senses VDD and provides an interrupt to the system when VDD falls below a selected threshold.
(LVD)
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.
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 I/O 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
noise
A device that imposes a signal on a carrier.
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.
A circuit that may be crystal controlled and is used to generate a clock frequency.
oscillator
parity
A technique for testing transmitted 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 below a pre-set level. This is one type of hardware
reset.

can be written in.
register
reset
A storage device with a specific capacity, such as a bit or byte.
A means of bringing a system back to a known 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.
serial
1. Pertaining to a process in which all events occur one after the other.
2. Pertaining to the sequential or consecutive occurrence of two or more related activities in a single device or
channel.
settling time

A memory storage device that sequentially shifts a word either left or right to output a stream of serial data.
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.

Glossary (continued)
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

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-built, 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.
A name for a power net meaning “voltage source.” The most negative power supply signal.
VSS
watchdog timer
A timer that must be serviced periodically. If it is not serviced, the CPU resets after a specified period of time.
