PSoC™ Mixed-Signal Array Final Dat a Sheet
CY8C21123,
CY8C21223, and CY8C21323
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 a rchi tec ture, as il lus trat ed on the l ef t, is com pri se d 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 PSoC device includes fo ur digi -
tal blocks. Depending on the PSoC package, up to two analog
comparators and up to 16 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

CY8C21x23 Final Data Sheet PSoC™ Over view
CPU core, called the M8C, is a powerful processor with speeds
up to 24 MHz. The M8C is a four MIPS 8-bit Harvard architec-
ture microprocessor.
System Resources provide additional capability, such as digital
clocks to increase the flexibility of the PSoC mixed-signal
arrays, I2C functionality for implementing an I2C master, slave,
MultiMaster, an internal voltage reference that provides an
absolute value of 1.3V to a number of PSoC subsystems, a
switch mode pump (SMP) that generates normal operating volt-
ages off a single battery cell, and various system resets sup-
ported by the M8C.
The Digital System is composed of an array of digital PSoC
blocks, which can be configured into any number of digital
peripherals. The digital blocks can be connected to the GPIO
through a series of global busses that can route any signal to
any pin. Freeing designs from the constraints of a fixed periph-
eral controller.
The Analog System is composed of four analog PSoC blocks,
supporting comparators and analog-to-digital conversion up to
8 bits in precision.
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 b lock s to form 8 , 16, 2 4, and 32-bit p eriphe rals, wh ich
are called user module references. Digital peripheral configura-
tions include those listed below.
PWMs (8 to 32 bit)
PWMs with Dead band (8 to 32 bit)
Counters (8 to 32 bit)
Ti mers (8 to 32 bit)
UART 8 bit with selectable parity (up to 4)
SPI master and slave
I2C slave, master, multi-master (1 availab le as a System
Resource)
Cyclical Redundancy Checker/Generator (8 to 32 bit)
IrDA (up to 4)
Pseudo Random Sequence Generators (8 to 32 bit)
The digital blocks can be connected to any GPIO through a
series o f global busses tha t can route any sign al to any pin. The
busses also allow for signal multiplexing and for performing
logic ope rations . This config urabil ity frees yo ur desi gns fro m 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 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.
Digital System Block Diagram
The Analog System
The Analog System is composed of 4 configurable blocks to
allow creation of complex analog signal flows. Analog peripher-
als 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 listed
below.
Analog-to-digital converters (single or dual, with 8-bit resolu-
tion)
Pin-to-p in co mparators (1)
Single-ended comparators (up to 2) with absolute (1.3V) ref-
erence or 8-bit DAC reference
1.3V reference (as a System Resourc e)
In most PSoC devices, analog blocks are provided in columns
of three, which includes one CT (Continuous Ti me) and two SC
(Switched Capacitor) blocks. The CY8C21x23 devices provide
limited functionality Type “E” analog blocks. Each column con-
tains one CT block and one SC bloc k.
The number of blocks is on the device family which is detailed
in the table titled “P SoC De vi ce Char a cte ris t ic s” on p age 3.

Additional System Resources
System Resources, some of which have been previously listed,
provide additional capability useful to complete systems. Addi-
tional resources include a switch mode pump, low voltage
detection, and power on reset. Brief statements describing the
merits of each system resource are presented below.
Digital clock dividers provide three customizable clock fre-
quencie s for use in applic ations . The clock s can be routed to
both the di git al and anal og systems . Additiona l clocks c an be
generated using digital PSoC blocks as clock divi ders.
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 appli-
cation of falling voltage levels, while the advanced POR
(Power On Reset) circuit eliminates the need for a system
supervisor.
An internal 1.3 voltage reference provides an absolute refer-
ence for the analog system, including ADC s and DACs.
An integrated switch mode pump (SMP) generates no rmal
operating voltages fr om a single 1.2 V battery cell, pro viding a
low cost boost convert er.

PSoC Designer Software Subsystems
Device Editor
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 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-
gram ming in co nju nctio n w ith t he De vice D ata Sh eet. Once t he
framework is generated, the user can add application-specific
code t o fle sh out the framework. It’ s als o po ss ible to change the
selecte d com pon ents and regenerate the framew or k.
Design Browser
The Design Browser allows users to select and import precon-
figu r ed de si g ns into th e u se r’s pro jec t. Use r s ca n eas il y br o wse
a catalog of preconfigured designs to facilitate time-to-design.
Examples pro vid ed in the tool s include a 300-baud m od em , LIN
Bus master and slave, fan controller, and magnetic card reader.
Applicati on Ed itor
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-
matical ly us e abso lut e addre ssing or ca n be co mpil ed in re lat ive
mode, and linked with other software modules to get absolute
addressing.
C Language Compiler. A C language compiler is available
that supports PSoC family devices. Even if you have never
worked i n the C la nguage bef ore, the p roduct qui ckly all ows 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.
Debugger
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.
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 des ig ner in getting started.
Hardware Tools
In-Circuit Emulator
A low cost, high functionality ICE (In-Circuit Emulator) is avail-
able for development support. This hardware has the capability
to program sing le dev ic es .
The emulator consists of a base unit that connects to the PC by
way of the parallel or 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

CY8C21x23 Final Data Sheet PSoC™ Over view
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 fle xibil ity tha t p ays divi dends in mana ging s pecifi catio n
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 h as several registers that determine its function and
connectivity to other blocks, multiplexers, busses and to the IO
pins. Itera tiv e de vel opment cy cl es perm it y ou to ada pt 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.
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 fun cti on s to control and respond to hardware event s at ru n
time. The API also provides optional interrupt service routines
that you can adapt as needed.
The API functions are documented in user module data sheets
that are vie wed directly in the PSoC Desi gn er ID E. Th es e data
sheets explain the internal operation of the user module and
provide performance specifications. Each data sheet describes
the use of e ac h us er m od ule p ara me ter a nd documents the se t-
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
configura tio n or move on to develo ping co de for the proj ect, yo u
perform the “Generate Application” step. This causes PSoC
Designer to generate source code that automatically configures
the devic e to y our s pe cif ic atio n an d pro vi des the high -le vel us er
module API functions.
User Module and Source Code Development Flows
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 last ste p in the development proc es s takes place insi de 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
breakpoi nt ev ents that include m oni tori ng ad dres s and da ta bus
values, memory locations and external signals.

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.
