The PIC18F66K22-I/PTRSL is a 64kB high-performance enhanced Flash Microcontroller Unit (MCU) with 12-bit A/D and nanoWatt XLP technology. This microcontroller is well suited for power-constrained and battery-powered applications. The Charge Time Measurement Unit (CTMU) simplifies the design of capacitive touch applications and can enable other applications requiring precise time or temperature measurement. Robust features such as wide operating voltage and temperature ranges and high endurance flash program and data EEPROM make this an excellent microcontroller for rugged automotive and industrial applications. Additional peripherals, such as a 12-bit A/D converter, 3 comparators H/W RTCC, 10 total CCP/ECCP channels, 11 total timers and 53 general purpose I/O. The consistent pinout scheme, used throughout the entire family, also aids in migrating to the next larger device.
