The PIC18FXXXX family offers the largest range of
on-chip enhanced FLASH program memory and the
richest selection of peripherals in the current line of
Microchip microcontrollers. The PIC18F8XXX subset is
made up of 80-pin parts that further extend the capabil-
ities by providing access to external memory devices.
Through the addition of external memory devices, an
8-bit application has the power to utilize unprecedented
amounts of code or data; up to 2 Mbytes for an 8-bit
microcontroller! AN869
