PSoC Functional Overview
The PSoC family consists of many mixed-signal arrays 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 analog and digital blocks, and
programmable interconnect. This architecture allows 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 config-
urable IO are included in a range of convenient pinouts.
IDAC
Vr
The PSoC architecture for this device family is comprised of
three main areas: Core, System Resources, and CapSense
Analog System. A common, versatile bus allows connection
between IO and the analog system. Each PSoC device includes
a dedicated CapSense block that provides sensing and scanning
control circuitry for capacitive sensing applications. Depending
on the PSoC package, up to 28 general purpose IO (GPIO) are
also included. The GPIO provide access to the MCU and analog
mux.

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 12 MHz. The M8C is a 2-MIPS, 8-bit Harvard
architecture microprocessor.

System Resources provide additional capability, such as a
configurable I2C slave or SPI master-slave communication
interface and various system resets supported by the M8C.
The Analog System is composed of the CapSense PSoC block
and an internal 1.8V analog reference. Together, they support
capacitive sensing of up to 28 inputs.
Analog Multiplexer System
The Analog Mux Bus connects to every GPIO pin. Pins are
connected to the bus individually or in any combination. The bus
also connects to the analog system for analysis with the
CapSense block comparator.
CapSense Analog System
The Analog System contains the capacitive sensing hardware.
Several hardware algorithms are supported. This hardware
performs capacitive sensing and scanning without requiring
external components. Capacitive sensing is configurable on
each GPIO pin. Scanning of enabled CapSense pins are
completed quickly and easily across multiple ports.
Switch control logic enables selected pins to precharge
continuously under hardware control. This enables capacitive
measurement for applications such as touch sensing. The
Analog Multiplexer System in the device family is optimized for
basic CapSense functionality. It supports sensing of CapSense
buttons, proximity sensors, and a single slider. Other multiplexer
applications include:
■ Capacitive slider interface.
■ Chip-wide mux that allows analog input from any IO pin.
■ Crosspoint connection between any IO pin combinations.
When designing capacitive sensing applications, refer to the
latest signal to noise signal level requirements application notes,
which are found in http://www.cypress.com
> DESIGN
RESOURCES > Application Notes. In general, and unless
otherwise noted in the relevant application notes, the minimum
signal-to-noise ratio (SNR) requirement for CapSense
applications is 5:1.

Code Generation Tools
Development Tools
PSoC Designer supports multiple third party C compilers and
assemblers. The code generation tools work seamlessly within
the PSoC Designer interface and have been tested with a full
range of debugging tools. The choice is yours.
PSoC Designer is a Microsoft® Windows-based, integrated
development
environment
for
the
Programmable
System-on-Chip (PSoC) devices. The PSoC Designer IDE runs
on Windows XP or Windows Vista.
This system provides design database management by project,
an integrated debugger with In-Circuit Emulator, in-system
programming support, and built-in support for third-party
assemblers and C compilers.
Assemblers. The assemblers allow assembly code to merge
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.
PSoC Designer also supports C language compilers developed
specifically for the devices in the PSoC family.
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.
PSoC Designer Software Subsystems
The optimizing C compilers provide all 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.
System-Level View
A drag-and-drop visual embedded system design environment
based on PSoC Express. In the system level view you create a
model of your system inputs, outputs, and communication inter-
faces. You define when and how an output device changes state
based upon any or all other system devices. Based upon the
design, PSoC Designer automatically selects one or more PSoC
Mixed-Signal Controllers that match your system requirements.
Debugger
The PSoC Designer Debugger subsystem 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 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.
PSoC Designer generates all embedded code, then compiles
and links it into a programming file for a specific PSoC device.
Chip-Level View
The chip-level view is a more traditional integrated development
environment (IDE) based on PSoC Designer 4.4. Choose a base
device to work with and then select different onboard analog and
digital components called user modules that use the PSoC
blocks. Examples of user modules are ADCs, 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.
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.
In-Circuit Emulator
The device editor also supports easy development of multiple
configurations and dynamic reconfiguration. Dynamic
configuration allows for changing configurations at run time.
A low cost, high functionality In-Circuit Emulator (ICE) is
available for development support. This hardware has the
capability to program single devices.
Hybrid Designs
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.
You can begin in the system-level view, allow it to choose and
configure your user modules, routing, and generate code, then
switch to the chip-level view to gain complete control over
on-chip resources. All views of the project share a common code
editor, builder, and common debug, emulation, and programming
tools.

property, and other information you may need to successfully
implement your design.
Designing with PSoC Designer
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.
Organize and Connect
You can build signal chains at the chip level by interconnecting
user modules to each other and the IO pins, or connect system
level inputs, outputs, and communication interfaces to each
other with valuator functions.
In the system-level view, selecting a potentiometer driver to
control a variable speed fan driver and setting up the valuators
to control the fan speed based on input from the pot selects,
places, routes, and configures a programmable gain amplifier
(PGA) to buffer the input from the potentiometer, an analog to
digital converter (ADC) to convert the potentiometer’s output to
a digital signal, and a PWM to control the fan.
The PSoC development process can be summarized in the
following four steps:
1. Select components
2. Configure components
3. Organize and Connect
4. Generate, Verify, and Debug
In the chip-level view, perform the selection, configuration, and
routing so that you have complete control over the use of all
on-chip resources.
Select Components
Both the system-level and chip-level views provide a library of
prebuilt, pretested hardware peripheral components. In the
system-level view, these components are called “drivers” and
correspond to inputs (a thermistor, for example), outputs (a
brushless DC fan, for example), communication interfaces
(I2C-bus, for example), and the logic to control how they interact
with one another (called valuators).
Generate, Verify, and Debug
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 software for the system.
In the chip-level view, the components are called “user modules”.
User modules make selecting and implementing peripheral
devices simple, and come in analog, digital, and mixed signal
varieties.
Both system-level and chip-level designs generate software
based on your design. The chip-level design 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. The system-level
design also generates a C main() program that completely
controls the chosen application and contains placeholders for
custom code at strategic positions allowing you to further refine
the software without disrupting the generated code.
Configure Components
Each of the components 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
correspond to your chosen application. Enter values directly or
by selecting values from drop-down menus.
A complete code development environment allows you to
develop and customize your applications in C, assembly
language, or both.
The last step in the development process takes place inside
PSoC Designer’s Debugger subsystem. The Debugger
downloads the and HEX image to the 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.
Both the system-level drivers and chip-level user modules are
documented in data sheets that are viewed directly in PSoC
Designer. These data sheets explain the internal operation of the
component and provide performance specifications. Each data
sheet describes the use of each user module parameter or driver

6. A maximum of 36 x 50,000 block endurance cycles is allowed. This is 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).
