According to the datasheet for the ADAU1462, the data memory size is 48kWords.
However, according to the compiler output window in Sigma Studio 3.17:
ADAU1452 - DM0: 20480, DM1:20480, PM: 8192 (OK)
ADAU1462 - DM0: 20480, DM1:20480, PM: 16384 (DM same as ADAU1452)
ADAU1466 - DM0: 40960, DM1:40960, PM: 24576 (OK)
According to the resources window, the ADAU1462 MaxProgramMemory is 24576 (this also seems to be an error).
We will be using the ADAU1462 in such a way that the DM requirements will be a bit greater than the capacity of the ADAU1452 (large FIR filters). I haven't actually tried compiling a program for the ADAU1462 that uses more DM than the ADAU1452 has but I am afraid that the compiler will give me an error when I do try it.
Is the datasheet correct?
