The PIC18 microcontroller family provides PICmicro®
devices in 18- to 80-pin packages, that are both socket
and software upwardly compatible to the PIC16 family. The
PIC18 family includes all the popular peripherals, such as
MSSP, ESCI, CCP, flexible 8- and 16-bit timers, PSP, 10-bit
ADC, WDT, POR and CAN 2.0B Active for the maximum
flexible solution. Most PIC18 devices will provide FLASH
program memory in sizes from 8 to 128 Kbytes and data
RAM from 256 to 4 Kbytes; operating from 2.0 to 5.5 volts,
at speeds from DC to 40 MHz. Optimized for high-level
languages like ANSI C, the PIC18 family offers a highly
flexible solution for complex embedded applications.
