Product Brief CP2056 V1.0 Touch Screen Controller Series 4-Wire Touch Screen Controller with Internal Reference General www.datasheet4u.com Description 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 reference that can be used for the auxiliary input, battery monitor, and temperature measurement modes. The reference can also be powered down when not used to conserve power. The CP2056 can make absolute or ratiometric measurements. The CP2056 is guaranteed to operate with a single 2.2V to 3.6V supply voltage.
