TMS570LS3137: emif bus storage mode

Annie Liu
Genius 10295 points
Part Number: TMS570LS3137
Other Parts Discussed in Thread: TMS570LC4357,

Hi Team,

The figure below is a screenshot of the datasheet of the TMS570LS3137 and TMS570LC4357. 4357 has two more NOTEs, which means its emif is in BE8 mode. Customer would like to know what mode is the emif of TMS570LS3137? Is it different from the 4357's mode?

 

Thanks,

Annie

    Hi Annie,

    The EMIF on TMS570LC4357 is in the BE-8 rather than BE-32 as in other Hercules devices (for example TMS570LS31x). If you are connecting a RAM to the EMIF then it should have no issue as the RAM is endianism neutral. If you are connecting a ASIC/FPGA you can swizzle between EMIF_DATA[15:8] and EMIF_DATA[7:0].
