PIC18 Microcontroller Family  
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.
