GPMC Controller

16-bit external memory controller

GPMC can communicate with many external devices:

External asynchronous/synchronous 8- bit wide memory/device

External asynchronous/synchronous 16-bit wide memory/device

External 16-bit non-multiplexed device with limited address range (2 Kbytes)

External 16-bit address/data- multiplexed NOR flash device

External 8-bit/16-bit NAND flash device

External 16-bit pseudo SRAM (pSRAM) device
