TMS570LC4357: EMIF trace length considerations for SRAM for the RM57/TMS570

Part Number: TMS570LC4357

Hello,

Are there any EMIF trace length considerations/layout considerations when using a 16 bit SRAM with the RM57/TMS570(4357) MCU?

Any document pointers for layout considerations would be much appreciated--

Best,

Josh Karch

    Hello Josh,

    Unfortunately, the only guide I can give is to have a look at the design files for our HDK boards. We don't have any specific documentation or recommendations in this regard other than to follow industry best practices which, in effect, is really not terribly helpful other than to say there is nothing unique about our device's EMIF interface relative to industry standards.

    Here is a link to the HDK design files for one of our TMS devices. TMS570LS31x Hercules Development Kit (HDK) Board Design Files

    Note that I included the design files for the LS3137 device because the posted documentation for the LC43xx only includes the schematic and not the board design files. The EMIF implementation should be the same (and the overall HDK) as the LC43xx is pin compatible to the LS3137.
