Features & Applications
PIC18LF14K22-I/P is a 8-bit Microcontroller has 16 Kbytes of Flash Program Memory in a 20 Pin PDIP package. It has an industrial temperature range from (-40°C to +85°C).

Introducing the nanoWatt XLP PIC18F1XK22 Flash microcontroller. This new family of devices offer all of the advantages of the well recognized PIC18F High Performance MCUs; 8-bit, C compiler optimized architecture and an industry leading peripheral set now available in a low pin-count option. These new 20-pin products include a 16 MHz precision Internal Oscillator which can be used with the standard 4X PLL to produce 16 MIPS of performance (64 MHz @ 3 V). Standard analog peripherals include 12 channels of 10-bit A/D, Dual Rail-Rail Comparators with improved input/output multiplexing and an on-chip selectable Fixed Voltage Reference. Digital peripherals include an Enhanced Capture/Compare/PWM (ECCP+) module with PWM steering and a Master Synchronous Serial Port (MI2C,SPI) module with software controllable address masking.
