External Memory Interfacing Techniques for the PIC18F8XXX
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 capabilities 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!
