CP2056 Datasheet (CHIP) - 4-Wire Touch Screen Controller

CP2056, 4-Wire Touch Screen Controller

The CP2056 is a 4-wire touch screen controller which supports a low-voltage I/O interface from 1.5V to 3.6V.

It contains a 12-bit analog-to-digital converter (ADC) with a synchronous serial interface and low on-resistance switches for driving resistive touch screens.

The CP2056 has an on-chip 2.5V
