TMS320F28075: EMIF1 to connect 16-bit and 8-bit asynchronous devices

Part Number: TMS320F28075

Vivek,

Thank you for your response to the previous thread.

In the previous thread we understood about connecting 1Mx16bit SRAM to the EMIF1_CS2n.

Then, my customer would like to add a 512Kx8bit SRAM to EMIF1_CS3n. Could you please advise again?

 

From the F28075 DS, p155: Table 6-3. EMIF Chip Select Memory Map

  

Q1. 

My customer would like to connect a couple of asynchronous devices:

  • EMIF1_CS2n: 1Mx16bit SRAM
  • EMIF1_CS3n: 512Kx8bit SRAM

 

Q.  Then, is it possible to add a 512Kx8bit SRAM to the EMIF1_CS3n and access whole the memory?

The table above doesn't show restrictions to CS3. I found no concerns, but I would like to make sure.

 

Q2.

We would expect the following address translation.

Could you please tell me if any concerns ?

From my previous thread, I modified the yellow cells for CS3n.
