AR1000 Series Resistive Touch Screen Controller

Microchip Technology 

AR1000 SERIES RESISTIVE TOUCH SCREEN CONTROLLER

11.1 Minimum Operating Voltage

The AR1000 series controller will operate down to 2.5V ± 5%. Touch performance will be optimized by using the

highest allowable voltage for the design.

The PICkit™ Serial included in the AR1000 Development kit supports 3V-5V range of operation.
