MICROCHIP PIC16LF1566-I/SO

The PIC16LF1566/1567 microcontrollers deliver unique on- chip features for the design of mTouch solutions and general purpose applications in 28/40/44- pin count packages. Two 10- bit high- speed ADCs with automated hardware CVD modules connect up to 34 analog channels to achieve a total sampling rate of 600k samples per second. This family provides mutual capacitance output drivers on all analog channels, two PWMs, two MSSP modules with low input- voltage options and one EUSART, which makes this family an excellent solution to implement low- power and noise- robust capacitive sensing and other front- end sampling applications with minimal software overhead.
