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, as well as programmable interconnect. This architecture
allows the user to create customized peripheral configurations,
to match the requirements of each individual application. Addi-
tionally, a fast CPU, Flash program memory, SRAM data mem-
ory, and configurable IO are included in a range of convenient
pinouts.
The PSoC architecture, as illustrated on the left, is comprised of
four main areas: the Core, the System Resources, the Digital
System, and the Analog System. Configurable global bus
resources allow all the device resources to be combined into a
complete custom system. Each PSoC device includes four digi-
tal blocks. Depending on the PSoC package, up to two analog
comparators and up to 16 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 (inter-
nal main oscillator) and ILO (internal low speed oscillator). The

PSoC™ Overview
PSoC Designer Software Subsystems
Device Editor
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 device editor also supports easy development of multiple
configurations and dynamic reconfiguration. Dynamic reconfig-
uration 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 pro-
gramming 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.
Design Browser
The Design Browser allows users to select and import precon-
figured 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, com-
pile, link, and build.
www.DataSheet4U.com
Assembler. The macro assembler allows the assembly code
to be merged seamlessly with C code. The link libraries auto-
matically 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 PSoC family 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.
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 the
program and read and write data memory, read and write IO
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.
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.
PSoC Express Software
PSoC Express is the first visual embedded system design tool
that allows a user to create an entire PSoC Project, generate a
schematic, BOM, and data sheet without writing a single line of
code. System designers are finally free from the low-level
implementation details of "micro-coding" to work directly with
application objects such as LEDs, switches, sensors, and fans.
Because the details of the actual firmware are left to the PSoC
Express firmware generation engine, and hidden from the user,
not only are design cycles reduced from weeks and months to a
few hours, but the generated, fully-tested ‘C' code is completely
standardized, considerably increasing overall design quality
and maintainability. Go to http://www.cypress.com/psocexpress
for free downloads and more information.
Hardware Tools
In-Circuit Emulator
A low cost, high functionality ICE (In-Circuit Emulator) is avail-
able 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 the parallel or 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
