IT7259： Self capacitance touch controller of wearable devices
IT7259 Is a 24/13 Channel capacitance sensor detection controller , With a ITO The membrane screen module can realize multi touch function . It integrates a single electrode 24/13 Channel capacitance digital converter （CDC）, A high-performance low-power RISC CPU, Flexible memory support , And many powerful hardware functions . Inside CDC There is an automatic calibration and compensation engine , To eliminate the impact of environmental changes .
IT7259 Support only I2C Interface . The serial interface is used to communicate with the host .
IT7259 use 32 Pad XQFN and 24 Pad QFN encapsulation . It needs a 2.6V-3.6V The power supply ,IO The voltage level can work at 1.8V-3.6V.
