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,
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 IO 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 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
(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.
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 module references. 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
■
I2C slave and multi-master
■
Cyclical Redundancy Checker/Generator (8 to 32 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.
System Resources provide the following additional capabilities:
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 Table 1 on page 4.

The Analog System
The Analog Multiplexer System
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:
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.
■
Analog-to-digital converters (single or dual, with 8-bit
resolution)
■
Pin-to-pin comparator
■
Single-ended comparators (up to 2) with absolute (1.3V)
reference or 8-bit DAC reference
■
Track pad, finger sensing.
1.3V reference (as a System Resource)
■
Chip-wide mux that allows analog input from any IO pin.
■
Crosspoint connection between any IO pin combinations.
■
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 Mixed-Signal Array Technical Reference Manual for
detailed information on the CY8C21x34’s Type E analog blocks.

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.
■
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 1.3 voltage reference provides an absolute
reference for the analog system, including ADCs and DACs.
■
An integrated switch mode pump (SMP) generates normal
operating voltages from a single 1.2V battery cell, providing a
low cost boost converter.

Design Browser
The Design Browser enables users to select and import
preconfigured designs into the user’s project. Users can easily
browse a catalog of preconfigured designs to facilitate
time-to-design. Examples provided in the tools include a
300-baud modem, LIN Bus master and slave, fan controller, and
magnetic card reader.
Application Editor
In the Application Editor you can edit your C language and
Assembly language source code. You can also assemble,
compile, link, and build.
Assembler. The macro assembler allows the seamless
merging of the assembly code with C code. The link libraries
automatically use absolute addressing or are compiled in relative
mode, and linked with other software modules to get absolute
addressing.
C Language Compiler. A C language compiler that supports
the PSoC family of devices is available. Even if you have never
worked in the C language before, the product quickly helps you
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
PSoC Designer Software Subsystems
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 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.
Device Editor
The device editor subsystem enables 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
reconfiguration allows 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 programming in
conjunction with the Device Data Sheet. After the framework is
generated, the user can add application-specific code to flesh
out the framework. It is also possible to change the selected
components and regenerate the framework.
Document Number: 38-12025 Rev. *M
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.
Hardware Tools
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 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 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 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.
Each block has several registers that determine its function and
connectivity to other blocks, multiplexers, buses and to the IO
pins. Iterative development cycles permit you to adapt the
hardware and 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
Integrated 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
contains over 50 common peripherals such as ADCs, DACs
Timers, Counters, UARTs, and other uncommon 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 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. User modules also
provide tested software to cut your development time. The user
module application programming interface (API) provides
high-level functions to control and respond to hardware events
at run 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 viewed directly in the PSoC Designer IDE. These data
sheets explain the internal operation of the user module and
provide performance specifications. Each data sheet describes
the use of each user module parameter and documents the
setting 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 can 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 interconnecting user modules to each other and the IO pins. At this
stage, you must 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
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 high-level user
module API functions.

The next step is to write your main program, and any
sub-routines 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 generated 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
professional-strength “makefile” system to automatically analyze
all file dependencies and run the compiler and assembler as
necessary. 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 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 enables you to define complex
breakpoint events that include monitoring address and data bus
values, memory locations, and external signals.

Register Mapping Tables
The PSoC device has a total register address space of 512 bytes. The register space is referred to as IO space and is divided into
two banks. The XOI bit in the Flag register (CPU_F) determines which bank the user is currently in. When the XOI bit is set the user
is in Bank 1.
Note In the following register mapping tables, blank fields are Reserved and must not be accessed.
