Hi

This might be a silly question, but is it possible to save power by switching off peripherals individually when the 580 is _not_ in sleep mode ?

The current consumption is a bit high right now (around 25mA) and I want to bring it down. Is it possible to switch off individual peripheral blocks without putting the device in sleep mode ?
I am using the UART, I2C and app_easy_timers only with data stored in external winbond spi flash.

Thanks

Hi ankitdaf,

Hi ankitdaf,

You can shut down the peripherals, but not individualy, they all belong to the same power domain PD_PER, so you cant for instance shut down each peripheral at the time, for example only UART2 and leave all the others active.
