AWR6443: Memory allocation

Part Number: AWR6443

Dear Experts,

The current Technical Reference Manual (that I could take from your website) is from June 2020, and it doesn’t contain any references to AWR6443; thus, I’ve had to estimate a little bit based on the other  AWRs.

 My assumptions are the following:

 AWR6443 has:

    • 512kB (program) + 192kB (data) for the MSS
    • 768kB (mixed generic RAM?)

Total: ~1.4MB (as advertised).


Now, I’ve seen in the Technical Reference Manual that some AWRs have this L3 split with granularity of 64kB (i.e. AWR14xx) and others with 128kB (i.e. AWR16xx and AWR18xx).

 Question 1: What is the granularity for AWR6443? 64kB or 128kB?

 Question 2: If L3 is split into 6 banks of 128kB each, how can these banks be allocated? Can we use for example 5 banks (i.e. 640kB) for generic purposes and add this section to the 512kB (program RAM) from the main MSS?
