STM32H7 vs STM32MP1 for heterogenous application use case

[ramkumarkoppu]

For one of the heterogenous application use case, we would like run always-on code in Cortex-M4 and high end application, we have two options. either run Cortex-M7 if se select STM32H7 device or Cortex-A7 if select STM32MP1 device. Assuming that both of these devices allow Cortex-M4 as always-on and high end CPU (either M7 for STM32H7 or A7 for STM32MP1) and ignoring Linux support, which device more energy efficient. is it STM32H7 or STM32MP1?

Hi @ramkumarkoppu​ ,

The article How to define your low-power strategy in STM32MP1 wiki gives some power figures.

Hope it will help.
