PIC16LF1566/1567
28/40/44-Pin Flash, 8-Bit Microcontrollers with XLP Technology
Description
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.
