AM5708: Changing frequency for MPU and DSP on AM5708

Nomo

Part Number: AM5708

Hello,

Can we change the frequency for MPU and DSP on AM5708?
My customers are considering lowering power consumption by changing frequency.
However, in the datasheet, only the maximum frequency is described.
For example, can we operate the Arm Cortex A15 core at 300MHz?

If yes, could you tell us the procedure?

Best Regards,

Hi Nomo,

Yes, you can use AM57x Cortex-A15 at 300MHz. The Cortex A15 frequency does not have a lower limit. It can function all the way down to having the PLL in BYPASS.

For changing frequency, refer to below user guides and e2e threads:
