IT7257数据手册ITE中文资料规格书

描述 Description

The IT7257 is a 13/22-channel capacitance sensor detection controller companioned with one ITO film screenmodule to implement multi-touch functionality. It integrates one single electrode 13/22-channelcapacitance-to-digital converter (CDC), one high performance low-power-consumption RISC CPU, flexiblememory support, and many powerful hardware functions. The internal CDC has one automatic calibrate andcompensates engine to remove effect from environmental change.
