PIC16LF1559-I/SS

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.
