AM5728: EMIF Tool Entry for Twin-die DDR3 Device

Thariq CP

Part Number: AM5728

Hi,

We are using 4X Micron MT41K512M16VRP-107 twin-die SDRAM devices on our design based on AM5728 (each EMIF connected to 2 memory devices), for a total capacity of 4GB. The device configuration is 64 Meg x 8 x 8 banks x 2 die.

- What value should be filled for "Total number of banks" under section 1B of EMIF Tool- 8 or 16?

- Under Step 2- DDR Timings: Should the "Final Datasheet Value" match with the values specified in DDR datasheet?

- 32 data bits are used from the SoC: in this case Col9 has to be included in Step3- Address Mapping. Please confirm. The cell is highlighted in white, not green.

Regards,

Thariq

Hi,

The DDR tool for AM5728 is located here: https://www.ti.com/lit/pdf/sprac36

I do not see an option "Total number of banks" under section 1B, nor do I see anything related to address mapping.

Can you please check that you have the correct part # / corresponding tool?

Thanks!

Kevin

Hi,

I am using the wokrbook at this link (which is given on AM5728 product page>Software Development)): https://www.ti.com/tool/SITARA-DDR-CONFIG-TOOL

The App Note used is https://www.ti.com/lit/an/spracj0b/spracj0b.pdf, since sprac36 do not match with the workbook.

Please sahre link to the workbook specific to AM5728, if it is different.

Hi Kevin,

Can you please confirm if I am using the correct tool? Else share the link for the right one.

HI,

SPRACJ0B does not apply to AM5728. As provided in my previous reply, you should use SPRAC36. The link to the XLS is provided in the PDF.
