Digital System  
PSoC Functional Overview  
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 modules.  
The PSoC programmable system-on-chip series of products  
consists of many 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, as well as  
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.

System  
The PSoC architecture, shown in the Block Diagram on page 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[1] and six analog blocks.

The M8C CPU core is a powerful processor with speeds up to  
24 MHz (up to 12 MHz for E-grade devices), providing four MIPS  
(two MIPS for E-grade devices) 8-bit Harvard architecture micro-  
processor. The CPU uses an interrupt controller to simplify the  
programming of real time embedded events.

Program execution is timed and protected using the included  
Sleep Timer and Watch Dog Timer (WDT).  
Memory encompasses 16 KB of flash (8 KB for CY8C21x45  
devices) for program storage, 1 KB of SRAM (512 bytes for  
CY8C21x45 devices) for data storage, and EEPROM emulation  
using the flash. Program flash uses four protection levels on  
blocks of 64 bytes, allowing customized software IP protection.  
Digital peripheral configurations are:  
PWMs (8- to 32-bit)  
PWMs with deadband (8- to 32-bit)  
Counters (8- to 32-bit)  
The PSoC device incorporates flexible internal clock generators,  
including a 24-MHz internal main oscillator (IMO). For A-grade  
devices 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 required, the 32.768 kHz external crystal  
oscillator (ECO) is available for use as a 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.  
Timers (8- to 32-bit)  
One-shot and multi-shot modules  
Full or half-duplex 8-bit UART with selectable parity (up to two  
full-duplex or four half-duplex)  
SPI master and slave (up to four total) with programmable data  
length from 8 to 16 bits.  
Shift register (1- to 32-bit)  
I2C master, slave, or multi-master (one available)  
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. Each pin can also generate a system interrupt.  
CRC/generator (16-bit)  
IrDA (up to two)  
PRS generators (8- to 32-bit)  
Note  
1. CY8C22x45 devices have 2 digital rows with 8 digital blocks. CY8C21x45 devices only have 1 digital row with 4 digital blocks.

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.

Array Input Configuration  
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.

The programmable 10-bit SAR ADC is an optimized ADC with a  
fast maximum sample rate. 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.

CY8C21x45 and CY8C22x45 devices have six limited-function-  
ality Type 'E' analog blocks. These analog blocks are arranged  
in four columns. Each column contains one continuous time (CT)  
Type E block. The first two columns also have a switched  
capacitor (SC) type E block. Refer to the PSoC Technical  
Reference Manual for CY8C21x45 and CY8C22x45 devices for  
detailed information on the Type E analog blocks.  
Haptics TS2000 Controller  
The CY8C22x45H family of devices features an easy-to-use  
Haptics controller resource with up to 14 different effects. These  
effects are available for use with three different, selectable ERM  
modules.

sections, provide additional capability useful for complete  
systems. Additional resources include a MAC, low voltage  
detection, and power on reset. The merits of each system  
resource are:  
Depending on your PSoC device characteristics, the digital and  
analog systems can have varying numbers of digital and analog  
blocks. The following table lists the resources available for  
specific PSoC device groups. The PSoC families covered by this  
datasheet are highlighted in the table.

Getting Started  
Development Tools  
For in depth information, along with detailed programming  
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:  
details, see the PSoC® Technical Reference Manual.  
For up-to-date ordering, packaging, and electrical specification  
information, see the latest PSoC device datasheets on the web.  
Application Notes  
Cypress application notes are an excellent introduction to the  
wide variety of possible PSoC designs.

runs on Windows XP, Windows Vista, and Windows 7.  
Visit our growing library of solution focused designs. Here you  
can find various application designs that include firmware and  
hardware design files that enable you to complete your designs  
quickly.  
PSoC Designer Software Subsystems  
Design Entry  
Technical Support  
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.  
Technical support – including a searchable Knowledge Base  
articles and technical forums – is also available online. If you  
cannot find an answer to your question, call our Technical  
Support hotline at 1-800-541-4736.  
The tool also supports easy development of multiple configura-  
tions 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 a given application.  
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 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.  
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 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 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  
provide performance specifications. Each datasheet describes  
the use of each user module parameter, and other information  
you may need to successfully implement your design.  
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.  
Organize and Connect  
Online Help System  
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 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.  
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.  
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.  
A complete code development environment allows you to  
develop and customize your applications in either C, assembly  
language, or both.  
Designing with PSoC Designer  
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  
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.  
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 is summarized in four steps:

Registers  
This section lists the registers of this PSoC device family by mapping tables. For detailed register information, refer to the PSoC  
Technical Reference Manual for CY8C21x45 and CY8C22x45 devices.  
Register Conventions  
Register Mapping Tables  
The register conventions specific to this section are listed in the  
following table.  
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.

8. The erase/write cycle limit per block (Flash  
) is only guaranteed if the device operates within one voltage range. Voltage ranges are 3.0 V to 3.6 V and 4.75 V to  
ENPB  
5.25 V.  
9. For the full temperature range, the user must employ a temperature sensor user module (FlashTemp) or other temperature sensor and feed the result to the temperature  
argument before writing. Refer to the Flash APIs Application Note AN2015 for more information.  
10. The maximum total number of allowed erase/write cycles is the minimum Flash  
value multiplied by the number of flash blocks in the device.

Development Tool Selection  
This section presents the development tools available for the automotive CY8C21x45 and CY8C22x45 families.  
CY3280-22X45 Universal CapSense Controller Board  
Software  
The CY3280-22X45 controller board is an additional controller  
board for the CY3280-BK1 Universal CapSense Controller Kit.  
The Universal CapSense Controller kit is designed for easy  
prototyping and debug of CapSense designs with pre-defined  
control circuitry and plug-in hardware. The CY3280-22X45 kit  
contains no plug-in hardware. Therefore, it is only usable if  
plug-in hardware is purchased as part of the CY3280-BK1 kit or  
other separate kits. The kit includes:  
PSoC Designer  
At the core of the PSoC development software suite is PSoC  
Designer. Utilized by thousands of PSoC developers, this robust  
software has been facilitating PSoC designs for years. PSoC  
Designer is available free of charge at http://www.cypress.com.  
PSoC Designer comes with a free C compiler.  
PSoC Programmer  
CY3280-22X45 universal CapSense controller board  
CY3280-22X45 universal CapSense controller board CD  
DC power supply  
Flexible enough to be used on the bench in development, yet  
suitable for factory programming, PSoC Programmer works  
either as a standalone programming application or it can operate  
directly from PSoC Designer. PSoC Programmer software is  
compatible with both PSoC ICE-Cube In-Circuit Emulator and  
PSoC MiniProg. PSoC programmer is available free of charge at  
http://www.cypress.com.

CY3280-CPM1 CapSensePlus Module  
The CY3280-CPM1 CapSensePlus Module is a plug-in module  
board for the CY3280-22X45 CapSense controller board kit. This  
plug-in module has no capacitive sensors on it. Instead, it has  
other general circuitry (such as a seven-segment display,  
potentiometer, LEDs, buttons, thermistor) that can be used to  
develop applications that require capacitive sensing along with  
other additional functionality. To use this kit, a CY3280-22X45 kit  
is required.
