描述 Description

The IT7259E is a 24/17-channel capacitance sensor detection controller companioned with one ITO film screen module to implement multi-touch functionality. It integrates one single electrode 24/17-channel capacitance-to-digital converter (CDC), one high performance low-power-consumption 8-bit MCU, flexible memory support, and many powerful hardware functions. The internal CDC has one automatic calibrate and compensates engine to remove effect from environmental change.
