T1024 IFC connection with MRAM(SRAM)

safeerkt — Thu, 22 Dec 2016 09:19:49 GMT

Hi ,

We are planning to use QorIQ T1024 processor in one of our design.We want to interface a MRAM(SRAM archit) to the processor through IFC.We have a 4MBit MRAM with 19 address line and 8 data bit.could you please help me with the address and data mapping from processor to the MRAM part? Which all address and DA lines should I use and how should i map it?

Many Thanks,

Safeer.

Please look T1024 Reference Manual, Figure 23-65 "IFC to 8-bit NOR device interface" for example SRAM-like device connection. Please note reversal mapping - AD[0:7] to D[7:0] and AD[0:15]+ADDR[16:31] to A[31:0].

Have a great day,
Alexander

Hi Alexander,

Thank you very much for your support.

Just one more clarification,

In our SRAM part we have 19 address lines.So can I follow the below address mapping?

T1024 side SRAM side

----------------- ------------------

ADDR[16:31] A[15:0]

AD[12:15] A[19:16]

Could you please confirm this?

Many Thanks,

Safeer.

Yes, I do not see anything incorrect.
