1. Introduction

Thank you for your interest in the CY3270 PSoC®1 FirstTouch™ Kit (FTK). You can design your

own projects with Cypress's easy-to-use Integrated Development Environment (IDE), PSoC

Designer™, or by altering sample projects provided along with this kit. The CY3270 PSoC 1 FTK is

described in the Help guides and examples projects that are available. The project “MF_CS_SLIDE”

is programmed on the CY3270 PSoC 1 FTK as the default project for demonstration purposes. For

more information on the default project, refer to Chapter 5.

The CY3270 PSoC 1 FTK includes a USB interface dongle, referred to as the FTPC bridge, and a

multifunction expansion card, referred to as the FTMF Expansion Card. The FTMF Expansion Card

demonstrates a variety of applications using ‘PSoC Powered Peripherals’. The FTMF Expansion

Card connects to the bridge through the bridge’s built-in 8×2 pin expansion port. As the name

implies, the FTPC bridge forms the connection between the FTMF Expansion Card and the various

PC applications that control and communicate with the FTMF Expansion Card.

The FTPC bridge portion of the kit contains a programmed Cypress CY8C24894 PSoC that

performs all of the USB and expansion card interface functions. The firmware that is run by this

PSoC performs the following primary functions:

■Functions as a USB physical and logical interface

■Provides PSoC MiniProg emulation for in system serial programming (ISSP) of the expansion

cards

■Provides communications with the PSoC programming utility

■Performs HID data channel communications

■Performs expansion card I2C communications

■Performs expansion card SPI communications

There are no other active components inside of the FTPC bridge. All of these interfaces run on a sin-

gle PSoC device. Future projects for the FirstTouch kit allow you to modify the FTPC firmware and

try some USB Interface designs of your own.

The FirstTouch expansion card connects to the FTPC bridge through the bridge’s 8×2 pin expansion

port. This expansion port provides all of the necessary signals to program the host PSoC on the

expansion card. The expansion port also provides power, ground, and I2C or SPI communications to

and from the expansion card host PSoC and PC.

The FirstTouch expansion card has a dedicated host PSoC. Therefore, when it is programmed with

your design, the expansion cards can operate either detached from the FTPC bridge in standalone

mode or connected to your system hardware. It is necessary to provide power and ground for the

expansion card to operate in either of these two arrangements.

There are four unused analog or digital GPIO pins on the FTPC port and four unused analog or

digital GPIO pins on the expansion card. This allows you to create custom designs and connect the

signals you want to the FTPC bridge or the FirstTouch expansion cards. These GPIO pins on the

PSoC are not connected to the header by default; zero ohm resistors (R9-R12) must be placed to

use these GPIOs.

Introduction

Chapter 2 describes the installation and configuration of the CY3270 PSoC 1 FTK. Chapter 3

describes the kit operation. It explains the programming of a PSoC 1 device with the PSoC

Programmer, and the usage of the kit with the help of an example project. Chapter 4 describes the

hardware operation. Chapter 5 provides information about the firmware and example project.

The Appendix A section provides the schematics and BOM associated with the PSoC Designer 5.1.

You can evaluate the included sample projects and then experiment with the included hardware and

software to create your own designs.
