AM4372: Hardware / Software compatibility between different operational frequency

Junpei Kishi

Part Number: AM4372

Hi team,

I would like to ask you the difference between AM4372BZDNA60 and AM4372BZDNA80.
We are trying to port from BZDNA60 to BZDNA80.

In my understands, the difference is only maximum operational frequency, one run at 600MHz max, and the other one run at 800MHz max.
That's why, I think these chips has hardware and software compatibility.

If we need to change some register configuration or peripheral circuit, could you let me know?

Thanks and Best Regards,
Junpei

Hi team,

Additionally, we are aiming to run BZDNA80 devices at 600MHz.

Thanks for your supports,

You will have no issue running a 800MHz part at 600MHz.

Only consideration would be if your software uses the CTRL_DEV_ATTR register to determine and set the maximum CPU frequency. This is unusual for most products but worth highlighting.
