PSoC™ Functional Overview
The PSoC™ family consists of many Mixed-Signal Array with
On-Chip Controller devices. All PSoC family devices are
designed to replace traditional MCUs, system ICs, and the
numerous discrete components that surround them. The PSoC
CY8C24794 device is a unique member of the PSoC family
because it includes a full-featured, full-speed (12 Mbps) USB
port. Configurable analog, digital, and interconnect circuitry
enable a high level of integration in a host of industrial, consumer, and communication applications.
The PSoC architecture, as illustrated on the left, is comprised of
four main areas: PSoC Core, Digital System, Analog System,
and System Resources including a full-speed USB port. Configurable global busing allows all the device resources to be combined into a complete custom system. The PSoC CY8C24794
device can have up to seven IO ports that connect to the global
digital and analog interconnects, providing access to 4 digital
blocks and 6 analog blocks.

PSoC™ Overview
The PSoC Core
Digital peripheral configurations include those listed below.
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 utilizes an interrupt controller with up to 20
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 16K of Flash for program storage, 1K of
SRAM for data storage, and up to 2K of EEPROM emulated
using the Flash. Program Flash utilizes 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 8% 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. The clocks, together with programmable clock dividers (as a System Resource), provide the flexibility to integrate almost any timing requirement into the PSoC
device. In USB systems, the IMO will self-tune to ± 0.25% accuracy for USB communication.
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.
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 blocks to form 8, 16, 24, and 32-bit peripherals, which
are called user module references.

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 you the optimum choice of system resources for your application. Family
resources are shown in the table titled “PSoC Device Characteristics” on page 3.
The Analog System
The Analog System is composed of 6 configurable blocks, each
comprised 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 listed below.

Depending on your PSoC device characteristics, the digital and
analog systems can have 16, 8, or 4 digital blocks and 12, 6, or
4 analog blocks. The following table lists the resources
available for specific PSoC device groups. The device covered
by this data sheet is shown in the highlighted row of the table.
PSoC Device Characteristics
The Analog Mux Bus can connect to every GPIO pin in ports 05. Pins can 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. It can be
split into two sections for simultaneous dual-channel processing. An additional 8:1 analog input multiplexer provides a second path to bring Port 0 pins to the analog array.
Switch control logic enables selected pins to precharge continuously under hardware control. This enables capacitive measurement for applications such as touch sensing. Other

PSoC™ Overview
PSoC Designer Software Subsystems
Device Editor
Debugger
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 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.
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’s also possible to change the
selected components and regenerate the framework.
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
Design Browser
The Design Browser allows 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.
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 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.
Assembler. The macro assembler allows the assembly code
to be merged seamlessly with C code. The link libraries automatically use absolute addressing or can be compiled in relative
mode, and linked with other software modules to get absolute
addressing.
C Language Compiler. A C language compiler is available
that supports the PSoC family of devices. Even if you have
never worked in the C language before, the product quickly
allows 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.

PSoC™ Overview
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 as well as the software. This substantially lowers the risk
of having to select a different part to meet the final design
requirements.
Device Editor
User
Module
Selection
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.

Application
Application Editor
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 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 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 highlevel 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.

User Module and Source Code Development Flows
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.

‘3Ah’). Hexidecimal numbers may also be represented by a ‘0x’
prefix, the C coding convention. Binary numbers have an
appended lowercase ‘b’ (e.g., 01010100b’ or ‘01000011b’).
Numbers not indicated by an ‘h’ or ‘b’ are decimal.

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 should not be accessed.

Notes
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.
