PSoC Functional Overview
Digital System
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
a low cost single-chip programmable device. PSoC devices
include configurable blocks of analog and digital logic, and
programmable interconnects. This architecture allows 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 IO 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.

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 the device resources into a complete
custom system. The PSoC CY8C23x33 family can have up to
three IO ports that connect to the global digital and analog
interconnects, providing access to four digital blocks and four
analog blocks.

PSoC Core
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 IO).
The M8C CPU core is a powerful processor with speeds up to 24
MHz, providing a four 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).
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.
The PSoC device incorporates flexible internal clock generators,
including a 24 MHz IMO (internal main oscillator) accurate to
±2.5% 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 ILO (internal low speed oscillator) 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.
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.

■
PWMs with Dead band (8 to 32 bit)
■
Counters (8 to 32 bit)
■
Timers (8 to 32 bit)
■

■
Cyclical Redundancy Checker/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 4.

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 can 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 (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.

The device editor also supports easy development of multiple
configurations and dynamic reconfiguration. Dynamic
configuration 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 programming in
conjunction with the Device Data Sheet. Once 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.

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 and
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.
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

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 can 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.
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 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 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, you
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.
Figure 4. User Module/Source Code Development Flows
Device Editor
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 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
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

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 allows you define complex
breakpoint events that include monitoring address and data bus
values, memory locations and external signals.

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.

Notes
18. Maximum CPU frequency is 12 MHz at 3.3V. With the CPU clock divider set to 1, the external clock must adhere to the maximum frequency and duty cycle requirements.
19. 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.
20. The max sample rate in this R2R ADC is 3.0/8=375KSPS
