IDC 6681

電阻式觸控面板是由兩層具有導電性質的材料結合（ITO Indium Tin Oxide 或者是ATO Antimony Tin Oxide ）中間以絕緣Dots隔開，經由上下兩層互相接觸，產生類比壓降訊號，藉由線路輸出，再經過控制器轉換成數位訊號，最後由電腦計算出觸控的正確位置。 Description IDC-6681 is an 8-bit high performance RISC architecture microcontroller with USB interface. There are built-in 12-bit SAR analog-to-digital (ADC) converter and low on-resistance drivers for 5-wire resistive touch screens. IDC-6681 contains all the analog and digital circuitry necessary to complete a pen request. IDC-6681 is provided in a 32-lead LQFP package. 如需更進一步資料，歡迎您來電或來信詢問。汽車險
