Flash Code Protection
Cypress products meet the specifications contained in their particular Cypress PSoC Data Sheets. Cypress believes that its
family of PSoC products is one of the most secure families of its kind on the market today, regardless of how they are used.
There may be methods, unknown to Cypress, that can breach the code protection features. Any of these methods, to our
knowledge, would be dishonest and possibly illegal. Neither Cypress nor any other semiconductor manufacturer can guaran-
tee the security of their code. Code protection does not mean that we are guaranteeing the product as ‘unbreakable’.
Cypress is willing to work with the customer who is concerned about the integrity of their code. Code protection is constantly
evolving. We at Cypress are committed to continuously improving the code protection features of our products.

1. Introduction
Thank you for your interest in the CY8CKIT-031 PSoC®CapSense®Expansion Board Kit. The
PSoC CapSense Expansion Board Kit interfaces any of the CY3280 Universal CapSense Module
boards with CY8CKIT-001 PSoC Development kit or CY8CKIT-030 PSoC 3 Development Kit. This
kit enables you to develop CapSense solutions with the CY8C3280 Universal CapSense Module
boards. The CapSense component in PSoC Creator™ allows to develop CapSense solutions with
great ease. The example projects provided along with this kit give sample solutions.
The PSoC CapSense Expansion Board is based on the PSoC 3 and PSoC 5 family of devices.
PSoC 3 and PSoC 5 are based on Programmable System-on-Chip™ platform for 8-, 16-, and 32-bit
applications. It combines precision analog and digital logic with a high-performance 8051 single
cycle per instruction pipelined processor achieving ten times the performance of previous 8051
processors. With this PSoC, you can create the exact combination of peripherals and integrated
proprietary IP to meet the needs of your applications. You are no longer constrained by what you find
in a catalog.
1.1 Kit Contents
The CY8CKIT-031 PSoC CapSense Expansion Board Kit includes:
■CY8CKIT-031 PSoC CapSense Expansion Board
■CY3280-BMM Universal CapSense Matrix Button Module Kit
■CY3280-SLM Universal CapSense Linear Slider Module Kit

1.2 PSoC Creator
Cypress's PSoC Creator software is a state-of-the-art, easy-to-use integrated development
environment (IDE) that introduces a game-changing, hardware and software design environment
based on classic schematic entry and revolutionary embedded design methodology.
With PSoC Creator, you can:
■Automatically place and route select components and integrate simple glue logic normally
located in discrete muxes.
■Trade-off hardware and software design considerations allowing you to focus on what matters
and getting to market faster.
PSoC Creator also enables you to tap into an entire tools ecosystem with integrated compiler tool
chains, RTOS solutions, and production programmers to support both PSoC 3 and PSoC 5.

2.2 Hardware
WARNING: Static discharges from the human body can easily reach 20,000 volts. This can damage
the PSoC 3 device on the development kit. Ensure that any static is discharged before touching the
hardware.
■Ensure the development kit is powered off before making any connections
■Connect the PSoC CapSense Expansion Board Kit to the development kit being used
■Connect the CY3280-Universal CapSense Module Board to PSoC CapSense Expansion Board
Kit
■Power the development kit
2.3 Software
When installing the PSoC CapSense Expansion Board Kit, the installer checks if prerequisites,
PSoC Creator, PSoC Programmer, Windows Installer, .NET, Acrobat Reader, and KEIL Complier,
are installed in your PC. If these applications are not installed, then the installer prompts you to
