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.
The IT7266 supports I2C interface only. The serial interface is to communicate with the host.
The IT7266 is available in 33-ball WLCSP and 25-ball WLCSP packages. It needs only one power 1.7V-1.9V source, and IO voltage level can operate at 1.7V-1.9V.
