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...

Tamper Pin Output for RTC

Posted on July 25, 2013 at 14:15I am using STM32VLDISCOVERY board (with STM32F100RB) to develop a basic real time clock application. Since I do not have a 32kHz crystal for now, I am using LSI clock instead of LSE.When I debug the code, I can see RT...

UART baud rate error stm32f4xxG
