Power Consumption Reduction on MPC5673F

Hi, I am looking for a solution to reduce the power consumption of the mcu MPC5673F. The Issue is that during a power fail we should be able to save certain number of bytes in the Flash, before the energy buffer is depleted. With the current Hardware, it is not possible to save 128 bytes in the Flash. Increasing Size of the capacitor (energy buffer) is not possible.

 

Can someone provide a solution for this Problem?

Hi,

if you can't change the hardware, you can:

- re-configure output pins, so external load is minimized.

- use SIU_HLT register to stop peripherals.

- decrease the system clock. Erase/program operation is self-clocked, it does not depend on system clock.

Regards,

Lukas
