The PSoC family consists of many devices with on-chip
controllers. 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, 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 PSoC architecture, shown in Figure 1, consists of four main
areas: the Core, the System Resources, the Digital System, and
the Analog System. Configurable global bus resources allow
combining all the device resources 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 I/O (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
(internal main oscillator) and ILO (internal low speed oscillator).
The CPU core, called the M8C, is a powerful processor with
speeds up to 24 MHz. The M8C is a four MIPS 8-bit Harvard
architecture microprocessor.
System Resources provide the following additional capabilities:
■ Digital clocks for increased flexibility.
2
■ I
C functionality to implement an I2C master and slave.
■ An internal voltage reference, MultiMaster, that provides an
absolute value of 1.3V to a number of PSoC subsystems.
■ A switch mode pump (SMP) that generates normal operating
voltages off a single battery cell.
■ Various system resets supported by the M8C.
The Digital System consists of an array of digital PSoC blocks
that may be configured into any number of digital peripherals.
The digital blocks are connected to the GPIO through a series of
global buses that can route any signal to any pin, freeing designs
from the constraints of a fixed peripheral controller.
The Analog System consists of four analog PSoC blocks,
supporting comparators and analog-to-digital conversion up to
10 bits of precision.
The Digital System
The Digital System consists of 4 digital PSoC blocks. Each block
is an 8-bit resource that is used alone or combined with other
blocks to form 8, 16, 24, and 32-bit peripherals, which are called
user modules. Digital peripheral configurations include the
following.
■ PWMs (8 to 32 bit)
■ PWMs with Dead band (8 to 32 bit)
■ Counters (8 to 32 bit)
■ Timers (8 to 32 bit)
■ UART 8 bit with selectable parity
■ SPI master and slave
2
■ I
C slave and multi-master
■ Cyclical Redundancy Checker/Generator (8-bit)
■ IrDA
■ Pseudo Random Sequence Generators (8 to 32 bit)
The digital blocks are 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.
Digital blocks are provided in rows of four, where the number of
blocks varies by PSoC device family. This allows the optimum
choice of system resources for your application. Family
resources are shown in Ta b le 1 on page 4.

The Analog System consists of 4 configurable blocks that allow
the creation of complex analog signal flows. Analog peripherals
are very flexible and may be customized to support specific
application requirements. Some of the common PSoC analog
functions for this device (most available as user modules) are:
■ Analog-to-digital converters (single or dual, with 8-bit or 10-bit
resolution)
■ Pin-to-pin comparator
■ Single-ended comparators (up to 2) with absolute (1.3V)
reference or 8-bit DAC reference
■ 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
contains one CT Type E block and one SC Type E block. Refer
to the PSoC Technical Reference Manual for detailed infor-
mation on the CY8C21x34’s Type E analog blocks.
Figure 2. Analog System Block Diagram
The Analog Multiplexer System
The Analog Mux Bus can connect to every GPIO pin. Pins may
be connected to the bus individually or in any combination. The
bus also connects to the analog system for analysis with
comparators and analog-to-digital converters. An additional 8:1
analog input multiplexer provides a second path to bring Port 0
pins to the analog array.
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:
■ Track pad, finger sensing.
■ Chip-wide mux that allows analog input from any I/O pin.
■ Crosspoint connection between any I/O pin combinations.
When designing capacitive sensing applications, refer to the
signal-to-noise system level requirement found in Application
Note AN2403 on the Cypress web site at
http://www.cypress.com.
Additional System Resources
System Resources, some of which are listed in the previous
sections, provide additional capability useful to complete
systems. Additional resources include a switch mode pump, low
voltage detection, and power on reset. Brief statements
describing the merits of each system resource follow.
■ Digital clock dividers provide three customizable clock
frequencies for use in applications. The clocks may 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 a Microsoft® Windows-based, integrated
development environment for the Programmable
System-on-Chip (PSoC) devices. The PSoC Designer IDE runs
on Windows XP or 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 Software Subsystems
System-Level View
A drag-and-drop visual embedded system design environment
based on PSoC Express. In the system level view you create a
model of your system inputs, outputs, and communication interfaces. You define when and how an output device changes state
based upon any or all other system devices. Based upon the
design, PSoC Designer automatically selects one or more PSoC
On-Chip Controllers that match your system requirements.
PSoC Designer generates all embedded code, then compiles
and links it into a programming file for a specific PSoC device.
Chip-Level View
The chip-level view is a more traditional Integrated Development
Environment (IDE) based on PSoC Designer 4.4. 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. 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.
The device editor also supports easy development of multiple
configurations and dynamic reconfiguration. Dynamic
configuration allows for changing configurations at run time.
Hybrid Designs
You can begin in the system-level view, allow it to choose and
configure your user modules, routing, and generate code, then
switch to the chip-level view to gain complete control over
on-chip resources. All views of the project share a common code
editor, builder, and common debug, emulation, and programming
tools.
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 merge
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
The PSoC Designer Debugger subsystem 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.
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.
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 (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 can be summarized in the
following four steps:
1. Select components
2. Configure components
3. Organize and Connect
4. Generate, Verify, and Debug
Select Components
Both the system-level and chip-level views provide a library of
prebuilt, pretested hardware peripheral components. In the
system-level view, these components are called “drivers” and
correspond to inputs (a thermistor, for example), outputs (a
brushless DC fan, for example), communication interfaces
2
(I
C-bus, for example), and the logic to control how they interact
with one another (called valuators).
In the chip-level view, the components are called “user modules”.
User modules make selecting and implementing peripheral
devices simple, and come in analog, digital, and mixed signal
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 Pulse
Width Modulator (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.
Both the system-level drivers and chip-level user modules are
documented in data sheets that are viewed directly in PSoC
Designer. These data sheets explain the internal operation of the
component and provide performance specifications. Each data
sheet describes the use of each user module parameter or driver
property, and other information you may need to successfully
implement your design.
Organize and Connect
You can build signal chains at the chip level by interconnecting
user modules to each other and the I/O pins, or connect system
level inputs, outputs, and communication interfaces to each
other with valuator functions.
In the system-level view, selecting a potentiometer driver to
control a variable speed fan driver and setting up the valuators
to control the fan speed based on input from the pot selects,
places, routes, and configures a programmable gain amplifier
(PGA) to buffer the input from the potentiometer, an analog to
digital converter (ADC) to convert the potentiometer’s output to
a digital signal, and a PWM to control the fan.
In the chip-level view, perform the selection, configuration, and
routing so that you have complete control over the use of 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, perform the “Generate
Application” step. This causes PSoC Designer to generate
source code that automatically configures the device to your
specification and provides the software for the system.
Both system-level and chip-level designs generate software
based on your design. The chip-level design 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. The system-level
design also generates a C main() program that completely
controls the chosen application and contains placeholders for
custom code at strategic positions allowing you to further refine
the software without disrupting the generated code.
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 subsystem. The Debugger
downloads the HEX image to the 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.

3.6V and 4.75V to 5.25V.
11. A maximum of 36 x 50,000 block endurance cycles is allowed. This may be balanced between operations on 36x1 blocks of 50,000 maximum cycles each, 36x2
blocks of 25,000 maximum cycles each, or 36x4 blocks of 12,500 maximum cycles each (to limit the total number of cycles to 36x50,000 and that no single block
ever sees more than 50,000 cycles). For the full industrial range, the user must employ a temperature sensor user module (FlashTemp) and feed the result to
the temperature argument before writing. Refer to the Flash APIs Application Note AN2015 at http://www.cypress.com under Application Notes for more
