i.MX8MP operating range details confirmation

bino — Wed, 26 Jul 2023 06:55:37 GMT

Hi @riteshmpatel,

I would like to know about different modes like nominal, overdrive, and Super overdrive which are for VDD_ARM. There is a specific frequency mentioned for each mode. So I just need to ensure that it is okay to reduce the frequency to 1.2GHz while using the Super overdrive mode. Please confirm.
Also, if I am using Super overdrive mode for VDD_ARM then is there any issue/dependency to use the nominal mode in other power rails like Arm PLL supply voltage?

Regards,
Bino Mani

Hi @bino,

I hope you are doing well.

While using the super overdrive mode, one can reduce the frequency but cannot exceed the operating range of the frequency.

Also, when the super overdrive mode is used for VDD_ARM, VDD_ARM_PLL_0P8 shall be set as 0.95V. However, since VDD_ARM_PLL_0P8 comes from the same power source -VDD_SOC for all 0P8 peripherals, all PLL and peripherals will be powered from the same 0.95V power source no matter whether they are running at overdrive mode or not.

I hope it helps.

Thanks & Regards,
