WTD0001

The WTD0001 is designed as one kind of touch screen controller that is designed for electronic product which using four-wired resistance touch screen and PC RS232 peripheral application, for example handwriting pad, monitor touch screen and e-book. This device includes function for software filter; it can filter out unnecessary noise to lower flying-line producing rate. The purpose is to lower host affording in resistance touch screen to make your product can connect touch screen easily, and add your product additional value.

Features of the WTD0001 are:(1)8-bit micro controller base;(2)12-bit resolution analog to digital converter;(3)10-bit or 12-bit selectable absolute value of X and Y axis;(4)debounce and noise filter function;(5)RS232 serial interface;(6)single supply 2.4 V to 5.5 V;(7)SOP-20 package or dice;(8)direct driving touch screen no external transistors are required;(9)automatic wake up from screen touch (also could be disable);(10)automatic standby power down function;(11)standby current less then 1 uA @ 3V.
