资料介绍

This manual is for the Microchip C2 touch screen micro-controller. The TSHARC touch screen controllers and
software described within this document are to be used with surface capacitive touch screen products
manufactured by a variety of touch screen manufacturers with or without an electrical backshield. Touch screens
between manufacturers vary with regards to light transm ission, sensitivity, capacitance and other electrical
characteristics. Because touch screen quality and electr ical characteristics may vary between touch screen
technologies and manufacturers the actual, overall performance may vary between touch screen overlay
manufacturers’ products.

Included within this manual are the schematics and detailed printed circuit board artwork. The design for the C2
implements special precautions within t he circuitry layout. Microchip Technology Inc. has tested this final design.
Any modifications or alterations made to this design will affect the performance of your controller. Microchip does
not recommend any modifications or deviations from the TSHARC controller design shown.

A great deal of attention has been paid to eliminate potential problems with various touch screen manufacturers.
We have identified substantial specification variance within each manufacturer and between manufacturers touch
screens. While most of the manufactures we tested did fall within a functional specification, it is important to
request electrical and mechanical specifications from your touch screen overlay manufacturer to insure uniform
quality and performance.
