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...


STM32G4 Flash writes at BOR

Hello,We have currently moved on to the STM32G4 series, and we are now looking at a project where data will be occasionally written to flash under control of our own code. Of course, this exposes us to flash memory corruption during unforeseen power ...

stm32G4 interfacing with ESP32 Wroom

I am trying to communicate to ESP32 from STM32G4 using UART communication..the pins that i connected are GPIO16,17,pwr,GND on the esp32 side and tx-rx-3.3v-gnd on the stm side the baud rate is 115200, parity none stop bit 1 and flow control 0 on both...

Resolved! How to enable I2C Clock stretching

Hi ST.​I'm using STM32 L4P5 as a Master in I2C.​slave device is slow to write data, so I did the slave device do clock stretching for a moment.​Is there any enable related to clock stretching on L4P5?​If so, what's the way to enable it?​thank you​
