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...

RM0432 - HSITRIM default value might be wrong?

In the reference manual for STM32L4+ (RM0432), it states that the default value for HSITRIM[6:0] is 16, which seems to be the default for MCUs that have 5 bits allocated for the trimming value, not 7. The reset value is correct, but I suppose it shou...
