• Full-featured evaluation board for the TSC2003 4-wire resistive touch screen controller (TSC).
• Modular design for use with a variety of DSP and microcontroller interface boards.
The TSC2003EVM-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 TSC2003EVM is in Texas Instruments' modular EVM form factor, which allows direct evaluation of the
performance and operating characteristics of the TSC2003, and eases software development and system
prototyping. This EVM is compatible with the 5-6K Interface Evaluation Module (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 TSC2003EVM-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 TSC2003EVM 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.
