IT7259: Self-Capacitive Touch Controller for Wearable Devices

IT7259 is a 24/13-channel capacitive sensor detection controller, which can realize multi-touch function with an ITO film screen module. It integrates a single-pole 24/13-channel capacitance-to-digital converter (CDC), a high-performance low-power RISC CPU, flexible memory support, and many powerful hardware features. The internal CDC has an automatic calibration and compensation engine to remove the effects of environmental changes.

IT7259 only supports I2C interface. The serial interface is used to communicate with the host.

IT7259 is available in 32-pad XQFN and 24-pad QFN packages. It needs a 2.6V-3.6V power supply, and the IO voltage level can work at 1.8V-3.6V.
