Posted on June 11, 2013 at 08:59Hi,
I have selected an STM32F2 MCU for various reasons and I need to run it in the lowest power possible.
The CPU will run most of the time et low speed 4 or 8 Mhz. For this I was thinking to use a 16Mhz crystal and bypass the PLL to save power.
Does anybody have an idea of how much current I can expect to save?
Tks.
