TMS320C6x EMIF to external SDRAM/SGRAM interface: Interfacing external SDRAM or SGRAM to the Texas Instruments TMS320C6x digital signal processor (DSP) is simple compared to previous generations of TI DSPs because of the advanced External Memory Interface (EMIF). The EMIF is a glueless interface to a variety of external memory devices, including SDRAM, SBSRAM, Asynchronous SRAM and EPROM. This application report describes the EMIF control registers and SDRAM signals along with SDRAM functionality, including functions supported by the EMIF and performance considerations when used with the EMIF. The EMIF supports a glueless interface to 16 Mbit, 2 bank and 64 Mbit, 4 bank SDRAM, offering system designers an interface to high-speed and high-density memory. The table below lists the possible SDRAM configurations that are fully supported by the EMIF. General examples include each SDRAM configuration supported by the EMIF, including timing analysis.
