PSoC® Functional Overview
The PSoC® family consists of many Mixed-Signal Array 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 blocks of analog and digital
logic, as well as programmable interconnect. This architecture
allows the user to create customized peripheral configurations,
to match the requirements of each individual application. Addi-
tionally, a fast CPU, Flash program memory, SRAM data mem-
ory, and configurable IO are included in a range of convenient
pinouts.
The PSoC architecture, as illustrated on the left, is comprised of
four main areas: the Core, the System Resources, the Digital
System, and the Analog System. Configurable 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 28 general purpose IO (GPIO) are
also included. The GPIO provide access to the global digital
and analog interconnects.
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 IMO (inter-
nal main oscillator) and ILO (internal low speed oscillator). The

The Digital System
The Digital System is composed of 4 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, which
are called user module references. Digital peripheral configura-
tions include those listed below.
The Analog System
The Analog System is composed of 4 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 mod-
ules) are listed below.
■ PWMs (8 to 32 bit)
■ PWMs with Dead band (8 to 32 bit)
■ Counters (8 to 32 bit)
■ Analog-to-digital converters (single or dual, with 8-bit resolu-
■ Timers (8 to 32 bit)
tion)
■ UART 8 bit with selectable parity
■ SPI master and slave
■ Pin-to-pin comparator
■ Single-ended comparators (up to 2) with absolute (1.3V) ref-
erence or 8-bit DAC reference
■ I2C slave and multi-master
■ Cyclical Redundancy Checker/Generator (8 to 32 bit)
■ IrDA
■ 1.3V reference (as a System Resource)
In most PSoC devices, analog blocks are provided in columns
of three, which includes one CT (Continuous Time) and two SC
(Switched Capacitor) blocks. The CY8C21x34 devices provide
limited functionality Type “E” analog blocks. Each column con-
tains one CT Type E block and one SC Type E block. Refer to
the PSoC Mixed-Signal Array Technical Reference Manual for
detailed information on the CY8C21x34’s Type E analog blocks.
■ Pseudo Random Sequence 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 con-
straints of a fixed peripheral controller.
Digital blocks are provided in rows of four, where the number of
blocks varies by PSoC device family. This allows you the opti-
mum choice of system resources for your application. Family
resources are shown in the table titled “PSoC Device Charac-
teristics” on page 3.

PSoC Device Characteristics
The Analog Multiplexer System
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. The following table lists the resources
available for specific PSoC device groups. The PSoC device
covered by this data sheet is highlighted below.
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 com-
parators and analog-to-digital converters. An additional 8:1 ana-
log input multiplexer provides a second path to bring Port 0 pins
to the analog array.
PSoC Device Characteristics

CY8C21x34 Final Data Sheet
PSoC® Overview
PSoC Designer Software Subsystems
Device Editor
Debugger
The device editor subsystem allows the user to select different
onboard analog and digital components called user modules
using the PSoC blocks. Examples of user modules are ADCs,
DACs, Amplifiers, and Filters.
The PSoC Designer Debugger subsystem provides hardware
in-circuit emulation, allowing the designer to test the program in
a physical system while providing an internal view of the PSoC
device. Debugger commands allow the designer to read the
program and read and write data memory, read and write IO
registers, read and write CPU registers, set and clear break-
points, 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.
The device editor also supports easy development of multiple
configurations and dynamic reconfiguration. Dynamic reconfig-
uration allows for changing configurations at run time.
PSoC Designer sets up power-on initialization tables for
selected PSoC block configurations and creates source code
for an application framework. The framework contains software
to operate the selected components and, if the project uses
more than one operating configuration, contains routines to
switch between different sets of PSoC block configurations at
run time. PSoC Designer can print out a configuration sheet for
a given project configuration for use during application pro-
gramming in conjunction with the Device Data Sheet. Once the
framework is generated, the user can add application-specific
code to flesh out the framework. It’s also possible to change the
selected components and regenerate the framework.
Online Help System
The online help system displays online, context-sensitive help
for the user. 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 getting started.
Hardware Tools
In-Circuit Emulator
Design Browser
A low cost, high functionality ICE (In-Circuit Emulator) is avail-
able for development support. This hardware has the capability
to program single devices.
The Design Browser allows users to select and import precon-
figured designs into the user’s project. Users can easily browse
a catalog of preconfigured designs to facilitate time-to-design.
Examples provided in the tools include a 300-baud modem, LIN
Bus master and slave, fan controller, and magnetic card reader.
The emulator consists of a base unit that connects to the PC by
way of a USB port. The base unit is universal and will operate
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.
Application Editor
In the Application Editor you can edit your C language and
Assembly language source code. You can also assemble, com-
pile, link, and build.
Assembler. The macro assembler allows the assembly code
to be merged seamlessly with C code. The link libraries auto-
matically use absolute addressing or can be compiled in relative
mode, and linked with other software modules to get absolute
addressing.
C Language Compiler. A C language compiler is available
that supports the PSoC family of devices. Even if you have
never worked in the C language before, the product quickly
allows you to create complete C programs for the PSoC family
devices.
The embedded, optimizing C compiler provides all the features
of C tailored to the PSoC architecture. It comes complete with
embedded libraries providing port and bus operations, standard
keypad and display support, and extended math functionality.

PSoC® Overview
User Module and Source Code Development Flows
Designing with User Modules
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.
Each block has several registers that determine its function and
connectivity to other blocks, multiplexers, buses and to the IO
pins. Iterative development cycles permit you to adapt the hard-
ware as well as the software. This substantially lowers the risk
of having to select a different part to meet the final design
requirements.

To speed the development process, the PSoC Designer Inte-
grated Development Environment (IDE) provides a library of
pre-built, pre-tested hardware peripheral functions, called “User
Modules.” User modules make selecting and implementing
peripheral devices simple, and come in analog, digital, and
mixed signal varieties. The standard User Module library con-
tains over 50 common peripherals such as ADCs, DACs Tim-
ers, Counters, UARTs, and other not-so common peripherals
such as DTMF Generators and Bi-Quad analog filter sections.

Debugger
Each user module establishes the basic register settings that
implement the selected function. It also provides parameters
that allow you to tailor its precise configuration to your particular
application. For example, a Pulse Width Modulator User Mod-
ule 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. User modules also
provide tested software to cut your development time. The user
module application programming interface (API) provides high-
level functions to control and respond to hardware events at run
time. The API also provides optional interrupt service routines
that you can adapt as needed.

The next step is to write your main program, and any sub-rou-
tines using PSoC Designer’s Application Editor subsystem.
The Application Editor includes a Project Manager that allows
you to open the project source code files (including all gener-
ated code files) from a hierarchal view. The source code editor
provides syntax coloring and advanced edit features for both C
and assembly language. File search capabilities include simple
string searches and recursive “grep-style” patterns. A single
mouse click invokes the Build Manager. It employs a profes-
sional-strength “makefile” system to automatically analyze all
file dependencies and run the compiler and assembler as nec-
essary. Project-level options control optimization strategies
used by the compiler and linker. Syntax errors are displayed in
a console window. Double clicking the error message takes you
directly to the offending line of source code. When all is correct,
the linker builds a HEX file image suitable for programming.
The API functions are documented in user module data sheets
that are viewed directly in the PSoC Designer IDE. These data
sheets explain the internal operation of the user module and
provide performance specifications. Each data sheet describes
the use of each user module parameter and documents the set-
ting of each register controlled by the user module.
The development process starts when you open a new project
and bring up the Device Editor, a graphical user interface (GUI)
for configuring the hardware. You pick the user modules you
need for your project and map them onto the PSoC blocks with
point-and-click simplicity. Next, you build signal chains by inter-
connecting user modules to each other and the IO pins. At this
stage, you also configure the clock source connections and
enter parameter values directly or by selecting values from
drop-down menus. When you are ready to test the hardware
configuration or move on to developing code for the project, you
perform the “Generate Application” step. This causes PSoC
Designer to generate source code that automatically configures
the device to your specification and provides the high-level user
module API functions.
The last step in the development process takes place inside the
PSoC Designer’s Debugger subsystem. The Debugger down-
loads the HEX image to the In-Circuit Emulator (ICE) where it
runs at full speed. Debugger capabilities rival those of systems
costing many times more. In addition to traditional single-step,
run-to-breakpoint and watch-variable features, the Debugger
provides a large trace buffer and allows you define complex
breakpoint events that include monitoring address and data bus
values, memory locations and external signals.

Hexidecimal numbers are represented with all letters in upper-
case with an appended lowercase ‘h’ (for example, ‘14h’ or
‘3Ah’). Hexidecimal numbers may also be represented by a ‘0x’
prefix, the C coding convention. Binary numbers have an
appended lowercase ‘b’ (e.g., 01010100b’ or ‘01000011b’).
Numbers not indicated by an ‘h’, ‘b’, or 0x are decimal.

a. 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 will 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.
