Low-cost, general-purpose microcontrollers with built-in capacitive sensing

The Capacitive-Sensing Module (CSM) present on all PIC16F722/3/4/6/7 MCUs, simplifies the amount of hardware and software setup required to implement a touch-sensing interface.

The CSM integrates analogue MUXs for monitoring up to 16 capacitive-sensor inputs. An integrated capacitive-sensing oscillator and multiple timer resources offer design flexibility, and the CSM can operate while the device is in sleep mode, reducing power consumption.

The 28- and 40-pin PIC16F72x MCUs are capable of operation down to 1.8V and feature a 16MHz internal oscillator; up to 14 ADC channels, SPI, I²C™ and AUSART communication and two Capture, Compare and PWM (CCP) modules. The highly-integrated devices are suitable for a wide range of general-purpose applications that require a touch-sensing interface.
