Using External Data Memory with PIC24F/24H/dsPIC33F

AN1210: the methodology to use the Parallel Master Port (PMP) module to interface with external data memory; either external Flash or external RAM.

Using the PMP module, the memory devices with 64K locations (Kbytes or K words) can be interfaced with no extra I/Os and software. This application note describes how to interface the memory devices with more than 64K locations using some I/O pins and provides the required APIs.
