PSoC Functional Overview
Digital System
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 a low-cost single-chip programmable device.
PSoC devices include configurable blocks of analog and digital
logic, and programmable interconnects. This architecture make
it possible for you to create customized peripheral configurations
that match the requirements of each individual application.
additionally, a fast central processing unit (CPU), flash memory,
SRAM data memory, and configurable I/O are included in a
range of convenient pinouts and packages.
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 module references.

Configuration
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 also has the capability to generate a
system interrupt on high level, low level, and change from last
read.

DIGITAL SYSTEM
The PSoC core is a powerful engine that supports a rich feature
set. The core includes a CPU, memory, clocks, and configurable
general Purpose I/O (GPIO)
The PSoC device incorporates flexible internal clock generators,
including a 24 MHz internal main oscillator (IMO) accurate to
±5% [2] over temperature and voltage. The 24 MHz IMO can also
be doubled to 48 MHz for use by the digital system. A low power
32 kHz internal low speed oscillator (ILO) is provided for the
sleep timer and WDT. If crystal accuracy is desired, 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.

Digital PSoC Block Array
PSoC Core
Memory encompasses 8 KB of flash for program storage, 256
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.

Digital Clocks
FromCore
The PSoC architecture, as shown in the Logic Block Diagram on
page 1, consists of four main areas: PSoC core, digital system,
analog system, and system resources. Configurable global
busing allows combining all of the device resources into a
complete custom system. The PSoC CY8C23x33 family can
have up to three I/O ports that connect to the global digital and
analog interconnects, providing access to four digital blocks and
four analog blocks.
The M8C CPU core is a powerful processor with speeds up to
24 MHz, providing a four million instructions per second MIPS
8-bit Harvard-architecture microprocessor. The CPU uses an
interrupt controller with 11 vectors, to simplify programming of
real time embedded events. program execution is timed and
protected using the included sleep and watch dog timers (WDT).

Digital peripheral configurations are:
■
PWMs (8-and 16-bit)
■
PWMs with Dead band (8- and 16-bit)
■
Counters (8- to 32- bit)
■
Timers (8- to 32- bit)
■
UART 8 bit with selectable parity (up to 1)
■
Serial peripheral interface (SPI) master and slave (up to 1)
■
I2C slave and multi master (1 available as a system resource)
■
Cyclical redundancy checker (CRC)/Generator (8 to 32 bit)
■
IrDA (up to 1)
■
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
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 the table titled PSoC Device Characteristics on page 5.
Note
2. Errata: When the device is operated within 0 °C to 70 °C, the frequency tolerance is reduced to ±2.5%, but if operated at extreme temperature (below 0 °C or above
70 °C), frequency tolerance deviates from ±2.5% to ±5%. For more information, see Errata on page 50.

The analog system consists of an 8-bit SAR ADC and four
configurable blocks. The programmable 8-bit SAR ADC is an
optimized ADC that runs up to 300 Ksps, with monotonic
guarantee. It also has the features to support a motor control
application.
Each analog block consists of an opamp circuit 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 more common PSoC
analog functions (most available as user modules) are:

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 multiplier, decimator,
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.
■
A multiply accumulate (MAC) provides a fast 8-bit multiplier
with 32-bit accumulate, to assist in both general math and
digital filters.
The decimator provides a custom hardware filter for digital
signal processing applications including the creation of delta
sigma ADCs.
The I2C module provides 100- and 400-kHz communication
over two wires. Slave, master, and multi-master modes are all
supported.
■
Low-Voltage detection interrupts can signal the application of
falling voltage levels, while the advanced POR circuit
eliminates the need for a system supervisor.
■
An internal 1.3-V reference provides an absolute reference for
the analog system, including ADCs and DACs.

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:
■
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
■
In-circuit emulation
Built-in support for communication interfaces:
2
❐ Hardware and software I C 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.
■
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 analog-to-digital converters (ADCs),
digital-to-analog converters (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 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 lets you to use more than 100 percent of PSoC's
resources for an application.
Document Number: 001-44369 Rev. *I
Code Generation Tools
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.
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 the designer to read and
program and read and write data memory, and 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.
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 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 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:
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 eight bits of resolution. Using these parameters, you can
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 of 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 that you may need to successfully implement your design.
Document Number: 001-44369 Rev. *I
Organize and Connect
Build signal chains at the chip level by interconnecting user
modules to each other and the I/O pins. 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, 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 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 lets 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 (accessed 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. It lets
you to define complex breakpoint events that include monitoring
address and data bus values, memory locations, and external
signals.

Register Reference
Register Mapping Tables
This section lists the registers of the CY8C23433 PSoC device
by using mapping tables, in offset order.
Register Conventions
The register conventions specific to this section are listed in
Table 4.
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 Bank 0 and Bank 1. The XIO bit in the Flag
register (CPU_F) determines which bank the user is currently in.
When the XIO bit is set to 1 the user is in Bank 1.
Note In the following register mapping tables, blank fields are
reserved and must not be accessed.

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 0xthe Flash APIs Application Note AN2015 at http://www.cypress.com under Application Notes for more information.
12. 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.

Notes
20. Maximum CPU frequency is 12 MHz at 3.3 V. With the CPU clock divider set to 1, the external clock must adhere to the maximum frequency and duty cycle requirements.
21. If the frequency of the external clock is greater than 12 MHz, the CPU clock divider must be set to 2 or greater. In this case, the CPU clock divider ensures that the
fifty percent duty cycle requirement is met.
22. The max sample rate in this R2R ADC is 3.0/8=375KSPS
23. 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.

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.

compiler
A program that translates a high level language, such as C, into machine language.
configuration
space
In PSoC devices, the register space accessed when the XIO bit, in the CPU_F register,
is set to ‘1’.
crystal oscillator
An oscillator in which the frequency is controlled by a piezoelectric crystal. Typically a piezoelectric
crystal is less sensitive to ambient temperature than other circuit components.
cyclic redundancy A calculation used to detect errors in data communications, typically performed using a linear
check (CRC)
feedback shift register. Similar calculations may be used for a variety of other purposes such as
data compression.
data bus
A bi-directional set of signals used by a computer to convey information from a memory location
to the central processing unit and vice versa. More generally, a set of signals used to convey
data between digital functions.
debugger
A hardware and software system that allows the user to analyze the operation of the system
under development. A debugger usually allows the developer to step through the firmware one
step at a time, set break points, and analyze memory.
dead band
A period of time when neither of two or more signals are in their active state or in transition.
digital blocks
The 8-bit logic blocks that can act as a counter, timer, serial receiver, serial transmitter, CRC
generator, pseudo-random number generator, or SPI.
digital-to-analog
(DAC)
A device that changes a digital signal to an analog signal of corresponding magnitude. The analogto-digital (ADC) converter performs the reverse operation.
duty cycle
The relationship of a clock period high time to its low time, expressed as a percent.
emulator
Duplicates (provides an emulation of) the functions of one system with a different system, so that
the second system appears to behave like the first system.
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 users with 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. A Flash block holds 64 bytes.
frequency
The number of cycles or events per unit of time, for a periodic function.
gain
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 Philips Semiconductors (now NXP Semiconductors). I2C is an
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.

ICE
The in-circuit emulator that allows users 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
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.
low-voltage detect A circuit that senses VDD and provides an interrupt to the system when VDD falls lower than a
(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.

Glossary
(continued)
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
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.
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
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.

Glossary
(continued)
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.

Fix Status
Silicon fix is planned.
1. Internal Main Oscillator (IMO) Tolerance Deviation at Temperature Extremes
■ Problem Definition
Asynchronous Digital Communications Interfaces may fail framing beyond 0 to 70°C. This problem does not affect end-product
usage between 0 and 70 °C.
■ Parameters Affected
The IMO frequency tolerance. The worst case deviation when operated below 0 °C and above +70 °C and within the upper
and lower datasheet temperature range is ±5%.
■ Trigger Condition(S)
The asynchronous Rx/Tx clock source IMO frequency tolerance may deviate beyond the data sheet limit of ±2.5% when
operated beyond the temperature range of 0 to +70 °C.
■ Scope of Impact
This problem may affect UART, IrDA, and FSK implementations.
■ Workaround
Implement a quartz crystal stabilized clock source on at least one end of the asynchronous digital communications interface.
■ Fix Status
The cause of this problem and its solution has been identified. Silicon fix is planned to correct the deficiency in silicon.
