New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...

STM32L452RE in stop mode (both stop0 and stop2) sometimes decide to ignore EXTI interrupts for a second or so.

I run my CPU mostly (when possible) in stop2 mode. I want EXTI interrupt from few pins to wake it up.                                What i found is that sometimes it doesn't.                                                                           ...

Pin configurations in low power modes

In the STM32L4 Nucleo examples, all GPIO on the processor are configured for analog mode before entering stop1 or stop2 modes. In a typical application, there will be some lines that must remain either high or low as to not turn on any external circu...

Resolved! STM32F0: Re-configure clocks after exiting stop mode

Hi All,I'm working with an STM32f091xC on a new design and I'm currently tryingto enable stop mode to conserve power without fully entering standbymode. I seem to be entering stop mode properly, but I'm having quite abit of trouble exiting stop mode....
