1.2 Introduction
2 Analog Interface
EVM Overview
• Full-featured evaluation board for the TSC2046 4-wire, resistive touch screen controller (TSC)
• Modular design for use with a variety of DSP and microcontroller interface boards
The TSC2046EVM-PDK is a complete evaluation kit, which includes a USB-based motherboard and
evaluation software for use with a personal computer running Microsoft Windows™ operating systems.
The TSC2046EVM is in Texas Instruments' modular EVM form factor, which allows direct evaluation of the
TSC2046 performance and operating characteristics, and eases software development and system
prototyping. This EVM is compatible with the 5-6K Interface Board (SLAU104) from Texas Instruments
and additional third party boards such as the HPA449 demonstration board from SoftBaugh, Inc.
(www.softbaugh.com ) and the Speedy33™ from Hyperception, Inc. (www.hyperception.com ).
The TSC2046EVM-PDK is a complete evaluation/demonstration kit, which includes a USB-based
motherboard called the USB-MODEVM Interface Board and evaluation software for use with a personal
computer running Microsoft Windows operating systems.
For maximum flexibility, the TSC2046EVM is designed for easy interfacing to multiple analog sources.
Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin,
dual-row, header/socket combination at J1. This header/socket provides access to the analog input pins of
the TSC. Consult Samtec at www.samtec.com or call 1-800-SAMTEC-9 for a variety of mating connector
options.
