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...



I have two stm32 on my board. I send serial data from stm32f407 to both max232 and stm32h743. The output data from the max232 is correct. but when I debug the stm32h743 input serial data, its data is incorrect. what is the problem?
