PSoC Functional Overview
The PSoC family consists of many On-Chip Controller devices.
These devices are designed to replace multiple traditional
MCU-based system components with one low cost single-chip
programmable device. PSoC devices include configurable
blocks of analog and digital logic, and programmable
interconnects. This architecture enables the user to create
customized peripheral configurations that 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
and packages.
Digital System
The Digital System is composed of eight digital PSoC blocks.
Each block is an 8-bit resource that may be used alone or
combined with other blocks to form 8, 16, 24, and 32-bit
peripherals, which are called user module references.

Configuration
The PSoC Core is a powerful engine that supports a rich feature
set. The core includes a CPU, memory, clocks, and configurable
GPIO (General Purpose I/O).
PSoC GPIOs provide connection to the CPU, digital, and analog
resources of the device. Each pin’s drive mode may be selected
from eight options, allowing great flexibility in external
interfacing. Every pin can also generate a system interrupt on
high level, low level, and change from last read.

DIGITAL SYSTEM
PSoC Core
The PSoC device incorporates flexible internal clock generators,
including a 24 MHz IMO (internal main oscillator). The 24 MHz
IMO can also be doubled to 48 MHz for use by the digital system.
A low power 32 kHz ILO (internal low speed oscillator) is
provided for the Sleep timer and WDT. If crystal accuracy is
required, the ECO (32.768 kHz external crystal oscillator) is
available for use as a Real Time Clock (RTC), and can optionally
generate a crystal-accurate 24 MHz system clock using a PLL.
The clocks, together with programmable clock dividers (as a
System Resource), provide the flexibility to integrate almost any
timing requirement into the PSoC device.
Port 2
Digital Clocks
From Core
The PSoC architecture, shown in Figure 1, consists of four main
areas: PSoC Core, Digital System, Analog System, and System
Resources. Configurable global busing allows the combining of
all the device resources into a complete custom system. The
PSoC family can have up to five I/O ports connecting to the
global digital and analog interconnects, providing access to eight
digital blocks and six analog blocks.
Memory encompasses 16 KB of Flash for program storage, 1K
bytes of SRAM for data storage, and up to 2 KB of EEPROM
emulated using the Flash. Program Flash uses four protection
levels on blocks of 64 bytes, allowing customized software IP
protection.
Port 1
Port 4
GOE[7:0]

Digital peripheral configurations are:
■
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 (Up to Two)
■
SPI Master and Slave (Up to Two)
■

■
Cyclical Redundancy Checker/Generator (8 to 32-Bit)
■
IrDA (Up to Two)
■
Pseudo Random Sequence Generators (8 to 32-Bit)
The digital blocks may 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 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 provides a choice of
system resources for your application. Family resources are
shown in Table 1 on page 5.

Analog System
Additional System Resources
The Analog System consists of a 10-bit SAR ADC and six
configurable blocks.
System Resources, some of which are listed in the previous
sections, provide additional capability useful to complete
systems. Additional resources include a MAC, low voltage
detection, and power on reset. The merits of each system
resource are:
The programmable 10-bit SAR ADC is an optimized ADC that
can be run up to 200 ksps with ± 1.5 LSB DNL and ± 2.5 LSB INL
(true for VDD ≥ 3.0V and Vref ≥ 3.0V). External filters are required
on ADC input channels for antialiasing. This ensures that any
out-of-band content is not folded into the input signal band.
Reconfigurable analog resources allow creating complex analog
signal flows. Analog peripherals are very flexible and may be
customized to support specific application requirements. Some
of the more common PSoC analog functions (most available as
user modules) are:
■
Analog-to-Digital converters (Single or Dual, with 8-bit
resolution)
■
Pin-to-pin Comparator
■
Single ended comparators with absolute (1.3V) reference or
5-bit DAC reference
■
1.3V reference (as a System Resource)
Analog blocks are provided in columns of four, which include
CT-E (Continuous Time) and SC-E (Switched Capacitor) blocks.
These devices provide limited functionality Type “E” analog
blocks.
Figure 2. Analog System Block Diagram
■
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.
■
Additional Digital resources and clocks optimized for CSD.
■
Support “RTC” block into digital peripheral logic.
■
A multiply accumulate (MAC) provides a fast 8-bit multiplier
with 32-bit accumulate, to assist in both general math and
digital filters.
■
The I2C module provides 100 and 400 kHz communication over
two wires. Slave, master, and multi-master modes are all
supported.
■
Low Voltage Detection (LVD) interrupts can signal the
application of falling voltage levels, while the advanced POR
(Power On Reset) circuit eliminates the need for a system
supervisor.
■
An internal 1.3V reference provides an absolute reference for
the analog system, including ADCs and DACs.

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
programmable system-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). 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.

CY8C21345
CY8C22345, CY8C22545
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.
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
(I2C-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 programmable
system-on-chip varieties.
Online Help System
Configure Components
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.
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.
In-Circuit Emulator
A low cost, high functionality ICE (In-Circuit Emulator) 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
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.
Document Number: 001-43084 Rev. *L
Both the system-level drivers and chip-level user modules are
documented in data sheets that are viewed directly in the 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.

CY8C21345
CY8C22345, CY8C22545
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.
Document Number: 001-43084 Rev. *L
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 the
PSoC Designer’s Debugger subsystem. The Debugger
downloads 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.

Registers
This section lists the registers of this PSoC device family by mapping tables. For detailed register information, refer the PSoC
Programmable System-on Chip Technical Reference Manual.
Register Conventions
Register Mapping Tables
Table 4. Abbreviations
The PSoC device has a total register address space of 512
bytes. The register space is also referred to as I/O space and is
broken into two parts. The XIO bit in the Flag register determines
which bank the user is currently in. When the XIO bit is set, the
user is said to be in the “extended” address space or the
“configuration” registers.
Convention

Note
7. 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 information.
8. The 50,000 cycle Flash endurance per block is guaranteed only if the Flash operates within one voltage range. Voltage ranges are 3.0V to 3.6V and 4.75V to 5.25V
9. All GPIOs meet the DC GPIO VIL and VIH specifications found in the DC GPIO specifications sections.The I2C GPIO pins also meet the above specs.

10. A Fast-Mode I2C-bus device may be used in a Standard-Mode I2C-bus system, but the requirement TSUDATI2C ≥ 250 ns must then be met. This is automatically 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 + TSUDATI2C = 1000 + 250 = 1250 ns (according to the Standard-Mode I2C-bus specification) before the SCL line is released.

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’ or ‘b’ are decimals.
Glossary
active high
5. A logic signal having its asserted state as the logic 1 state.
6. A logic signal having the logic 1 state as the higher voltage of the two states.
analog blocks
The basic programmable opamp circuits. These are SC (switched capacitor) and CT (continuous
time) blocks. These blocks can be interconnected to provide ADCs, DACs, multi-pole filters, gain
stages, and much more.
analog-to-digital
(ADC)
A device that changes an analog signal to a digital signal of corresponding magnitude. Typically,
an ADC converts a voltage to a digital number. The digital-to-analog (DAC) converter performs
the reverse operation.
API (Application
Programming
Interface)
A series of software routines that comprise an interface between a computer application and
lower level services and functions (for example, user modules and libraries). APIs serve as
building blocks for programmers that create software applications.
asynchronous
A signal whose data is acknowledged or acted upon immediately, irrespective of any clock signal.
bandgap
reference
A stable voltage reference design that matches the positive temperature coefficient of VT with
the negative temperature coefficient of VBE, to produce a zero temperature coefficient (ideally)
reference.
bandwidth

Inter-Integrated Circuit. 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 +5V and pulled high with resistors. The bus operates at 100
kbits/second in standard mode and 400 kbits/second in fast mode.

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.
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.

(LVD)
selected threshold.
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 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 below a pre-set level. This is
one 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.

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
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 allowing users to store and
retrieve data at a high rate of speed. The term static is used because, after a value has been
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.

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.
