PIC16LF1554/1559
20-Pin Flash, 8-Bit Microcontrollers with XLP Technology
Description
The PIC16LF1554/1559 microcontrollers with Microchip enhanced mid-range core deliver unique on-chip features for
the design of mTouch® solutions and general purpose applications in 14/20-pin count packages. Two 10-bit
high-speed ADCs with automated hardware CVD modules connect to up to 17 analog channels to achieve a total
sampling rate of 600k samples per second. Combined with two PWMs and multiple communication peripherals, this
microcontroller family is an excellent solution to implement low-power and noise-robust capacitive sensing and other
front-end sampling applications with minimal software overhead.
