TMS320F28388S: Tools and collateral to help for SDRAM design (selection, pinmux, schematics, PCB)?

Part Number: TMS320F28388S
Other Parts Discussed in Thread: SYSCONFIG, C2000WARE

Team,

Regarding SDRAM usage on F2838x

-What do we have available to help to start with the design of the SDRAM interface?
-Does sysconfig help for this (ROW/COL address config, on-chip DDR controler register configuration, timings)?
-What would be the minimum SDRAM configuration (ie size and pin usage) supported?
-Do we have an app note that can help starting? Typilcally do we provide some precise PCB guidelines so that no timings analysis need to be done? Or should the SDRAM be choosen doing timing analysis?
-Does Design and Usage Guidelines for the C2000 External Memory Interface (EMIF) (SPRAC96A) apply to F2838x to?
-Do we have a design example available (schematics, PCB) on any of the development boards (Control card, Launchpad, ..etc) that can be used as starting point?

Thanks in advance,

A.

    Yes, the App Note material is applicable to F2838x EMIF as well and is probably the best documentation guide to reference. The TRM EMIF section being good as well.

    You can see "EMIF Reference Design" in Appendix C in the document. It'll point you to the HW reference design that's in C2000WARE, meant to be interfaced with F28379D LaunchPad or ControlCard.

    Best,

    Hi Kevin,
    Thanks for the clarification.
    As you pointed out the Altium sch/PCB files are located in C:\TI\c2000\C2000Ware_xx_xx_xx\boards\TIDesigns\F28379D_EMIF_DC\.

    It uses the 16b x 16M AS4C16M16SA-6TIN SDRAM

    Is there a SW example that is associated with it for the different SDRAM controller register settings?
    Or may be an existing CCS GEL file?

    Thanks on advance,

    A.

    You can find reference example on F2837x device (C:\TI\c2000\C2000Ware_xx_xx_xx\device_support\f2837xd\examples\cpu1\emif_dc_*). EMIF interface is same on F2837x and F2838x device.
