Texas Instruments TMS320F2837 D Series Workshop Guide And Lab Manual

External Memory Interface (EMIF)
TMS320F2837xD Microcontroller Workshop - System Design 10 - 5
External Memory Interface (EMIF)
External Memory Interface (EMIF)
 Provides a means for the CPU, DMA, and CLA to connect
to various memory devices
 Support for synchronous (SDRAM) and asynchronous
(SRAM, NOR Flash) memories

F2837xD includes two EMIFs
 EMIF1 – 16/32-bit interface shared between CPU1 and CPU2
 EMIF2 – 16-bit interface dedicated to CPU1
