MM9Z1_638 Power consumption

Hi there,

I´m using a MM9Z1_938 and I need to reduce the power consumption because I want to reduce the self heating of the IC. Is there a possibly or configuration to reduce the power consumption of the IC?

Regards

Hi Boris,

The power consumption is proportional to the system clock frequency.

You need to reduce the frequency as much as possible for this application.

Hi,

thanks for the reply. The clock frequency way is working.

Are there any other ways aviable?

Hi @Boris_Bloxsberg,

Using the lower-power modes of the device.

Disabling unused peripherals:

Make sure no inputs are floating, especially in the low-power modes.
