STM32F0 - power

So I managed to get my boards programmed and working... except one little detail - power consumption is rather high for my application. With both UARTs on and nothing else, running on HSI at 48Mhz, current consumption is at 10.2mA when starting up and 9.5-9.3 once everything is initialized.

Any suggestions towards lowering that? Ideally under 5mA... if that's even possible?

Would hate having to switch to STM32L* now that all code was done?

TIA!

You may be right, the cpu core uses all four cycles to process single instruction, really simple cpu.

I understand ''really simple cpu'' as euphemism for ''botched''.

I have to work with this thing, which is not really funny...
