IT7266数据手册ITE中文资料规格书

描述 Description

The IT7266 is a 24-channel capacitance sensor detection controller companioned with one ITO film screen module to implement multi-touch functionality. It integrates one single electrode 24-channel capacitance-to-digital converter (CDC), one high performance low-power-consumption RISC CPU, flexible memory support, and many powerful hardware functions. The internal CDC has one automatic calibrate and compensates engine to get rid of the effect resulted from the environmental change.
