Product Brief
CP2056 V1.0
Touch Screen Controller Series
4-Wire Touch Screen Controller with Internal Reference
www.datasheet4Gu.econmeral 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. The typical power consumption at 125ksps throughput and a
2.7V supply (reference off) is lower than 0.75mW.
Low-power operation makes the CP2056 ideal for battery-operated
systems, such as personal digital assistants with resistive touch
screens and other portable equipment. The CP2056 is available in
QFN16, TSSOP16 packages and is specified over the -40℃ to +85℃
temperature range.
