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...

Would you tell me the condition(Hi/Low/Hiz/PullHigh/PullLow) of all ports of STM32G474 MCU chip when it gets boot mode with boo0 pin of high?

I'm building a new custom PCB with the MCU(STM32G4) chip and needs to get it updated with a new Firmware through UART by main computer. then I HAVE TO CARE all MCU pins so as NOT to make bad effects on other LSI during boot mode. I need to know all t...

STM32H723ZG Highest USART Baud Rate & Voltage Scaling

The datasheet of STM32H723ZG claims to have a highest USART baudrate at 12.5Mbit/s (with 100MHz kernel frequency and 8 oversampling). But with voltage scaling 0 (VOS0), it is possible to have a higher kernel frequency to 137.5MHz, and therefore the b...
