Figure 1. Analog System Block Diagram
PSoC Functional Overview
The PSoC family consists of on-chip Controller devices. These
devices are designed to replace multiple traditional MCU-based
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 configurable I/O are included in a range of
convenient pinouts.
IDAC
Vr
The architecture for this device family, as shown in the Logic
Block Diagram on page 2, is comprised of three main areas: the
Core, the CapSense Analog System, and the System Resources
(including a full speed USB port). A common, versatile bus allows
connection between I/O and the analog system. Each
CY8C20x36A/46A/66A/96A 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 36 general purpose IO (GPIO) are also
included. The GPIO provides access to the MCU and analog
mux.

CSCLK
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 4-MIPS, 8-bit Harvard archi-
tecture microprocessor.

Oscillator
System Resources provide additional capability, such as
configurable USB and I2C slave/SPI master-slave
communication interface, three 16-bit programmable timers, and
various system resets supported by the M8C.
Analog Multiplexer System
The Analog Mux Bus can connect 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.
The Analog System is composed of the CapSense PSoC block
and an internal 1.2V analog reference, which together support
capacitive sensing of up to 36 inputs.
Switch control logic enables selected pins to precharge
continuously under hardware control. This enables capacitive
measurement for applications such as touch sensing. Other
multiplexer applications include:
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.
■ Complex capacitive sensing interfaces, such as sliders and
touchpads.
■ Chip-wide mux that allows analog input from any I/O pin.
■ Crosspoint connection between any I/O pin combinations.
When designing capacitive sensing applications, refer to the
latest signal-to-noise signal level requirements Application
Notes, which can be found under http://www.cypress.com >
Documentation > Application Notes. In general, and unless
otherwise noted in the relevant Application Notes, the minimum
signal-to-noise ratio (SNR) for CapSense applications is 5:1.

Additional System Resources
Getting Started
System Resources, some of which are listed in the previous
sections, provide additional capability useful to complete
systems. Additional resources include low voltage detection and
power on reset. The merits of each system resource are listed
here:
The quickest way to understand PSoC silicon is to read this data
sheet and then use the PSoC Designer Integrated Development
Environment (IDE). This data sheet is an overview of the PSoC
integrated circuit and presents specific pin, register, and
electrical specifications.
■ The I2C slave/SPI master-slave module provides 50/100/400
kHz communication over two wires. SPI communication over
three or four wires runs at speeds of 46.9 kHz to 3 MHz (lower
for a slower system clock).
For in depth information, along with detailed programming
details, see the PSoC® Programmable System-on-Chip™
Technical Reference Manual for CY8C20x36A/46A/66A/96A
PSoC Devices.
■ The I2C hardware address recognition feature reduces the
already low power consumption by eliminating the need for
CPU intervention until a packet addressed to the target device
is received.
For up-to-date ordering, packaging, and electrical specification
information, see the latest PSoC device data sheets on the web
at www.cypress.com/psoc.
Application Notes
■ 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.
Application notes are an excellent introduction to the wide variety
of possible PSoC designs. They are located here:
www.cypress.com/psoc. Select Application Notes under the
Documentation tab.
■ An internal reference provides an absolute reference for capac-
itive sensing.
Development Kits
■ A register-controlled bypass mode allows the user to disable
the LDO.
PSoC Development Kits are available online from Cypress at
www.cypress.com/shop and through a growing number of
regional and global distributors, which include Arrow, Avnet, Digi-
Key, Farnell, Future Electronics, and Newark.
■ Standard Cypress PSoC IDE tools are available for debugging
the CY8C20x36A/46A/66A/96A family of parts. However, the
additional trace length and a minimal ground plane in the Flex-
Pod can create noise problems that make it difficult to debug
the design. A custom bonded On-Chip Debug (OCD) device is
available in an 48-pin QFN package. The OCD device is
recommended for debugging designs that have high current
and/or high analog accuracy requirements. The QFN package
is compact and is connected to the ICE through a high density
connector.

Development Tools
PSoC Designer is a Microsoft® Windows-based, integrated
development environment for the Programmable System-on-
Chip (PSoC) devices. The PSoC Designer IDE and application
runs on Windows XP and Windows Vista.
Code Generation 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.
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 assem-
blers and C compilers.
Assemblers. The assemblers allow assembly code to be
merged 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
System-Level View
The system-level view is a drag-and-drop visual embedded
system design environment based on PSoC Express. In this
view you solve design problems the same way you might think
about the system. Select input and output devices based upon
system requirements. Add a communication interface and define
the interface to the system (registers). Define when and how an
output device changes state based upon any/all other system
devices. Based upon the design, PSoC Designer automatically
selects one or more PSoC devices that match your system
requirements.
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.
Debugger
PSoC Designer has a debug environment that 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 I/O
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.
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.x. You 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. You configure the user modules for your
chosen application and connect them to each other and to the
proper pins. Then you 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
A low cost, high functionality In-Circuit Emulator (ICE) is
available for development support. This hardware has the
capability to program single devices.
The tool also supports easy development of multiple configura-
tions and dynamic reconfiguration. Dynamic reconfiguration
allows for changing configurations at run time.
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.
Hybrid Designs
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 common code
editor, builder, and common debug, emulation, and programming
tools.

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 build signal chains at the chip level by interconnecting user
modules to each other and the I/O 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, you 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
pre-built, pre-tested 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, you perform the “Generate
Configuration Files” step. This causes PSoC Designer to
generate source code that automatically configures the device to
your specification and provides the software for the system.
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.
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 programmable
system-on-chip varieties.
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 corre-
spond 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 (access by clicking the Connect
icon). PSoC Designer downloads the HEX image to the ICE
where it runs at full speed. PSoC Designer debugging capabil-
ities rival those of systems costing many times more. In addition
to traditional single-step, run-to-breakpoint and watch-variable
features, the debug interface provides a large trace buffer and
allows you to 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
property, and other information you may need to successfully
implement your design.
