Description:

PIC18(L)F2X/4X/6XK40 microcontrollers combine large Flash/EE/RAM memory, rich peripheral integration, XLP and

5V support to suit a variety of general purpose applications. These 28-pin, 40-pin and 64-pin devices deliver Core

Independent Peripherals such as CWG, WWDT, CRC/Memory Scan, Hardware CVD, Zero-Cross Detect, SMT and

Peripheral Pin Select, providing for increased design flexibility and lower system cost.
