PSoC Device Characteristics
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. Table 1 lists the resources available for specific
PSoC device groups. The PSoC device covered by this data
sheet is highlighted in this table.
Getting Started
The quickest path to understanding the PSoC silicon is by
reading this data sheet and using 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. For in-depth information with
detailed programming information, refer the PSoC Mixed-Signal
Array
Technical
Reference
Manual

Development Kits
Development Kits are available from the following distributors:
Digi-Key, Avnet, Arrow, and Future. The Cypress Online Store
contains development kits, C compilers, and all accessories for
PSoC development. Go to the Cypress Online Store web site at
http://www.cypress.com, click the Online Store shopping cart
icon at the bottom of the web page, and click PSoC (Program-
mable System-on-Chip) to view a current list of available items.
Technical Training Modules
Free PSoC technical training modules are available for users
new to PSoC. Training modules cover designing, debugging,
advanced
analog
and
CapSense.

Technical Support
PSoC application engineers take pride in fast and accurate
response. They can be reached with a 4-hour guaranteed
response at http://www.cypress.com/support.
Application Notes
A long list of application notes can assist you in every aspect of
your design effort. To view the PSoC application notes, go to the
http://www.cypress.com web site and select Application Notes
under the Design Resources list located in the center of the web
page. Application notes are sorted by date by default.
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 NT 4.0, Windows 2000, Windows
Millennium (Me), or Windows XP. (See Figure 3 on page 5)
PSoC Designer helps the customer to select an operating
configuration for the PSoC, write application code that uses the
PSoC, and debug the application. This system provides design
database management by project, an integrated debugger with
In-Circuit Emulator, in-system programming support, and the
CYASM macro assembler for the CPUs.
PSoC Designer also supports a high-level C language compiler
developed specifically for the devices in the family.
