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...

Unable to debug on STM32L151VE via IAR Embedded Workbench

We've got some piece of code that we would like to debug on the MCU. This works fine with the previous hardware version of our product, which uses an STM32L151RET6.On our new hardware version using the STM32L151VE, however, debugging from IAR does no...

What is the correct procedure to recover an STM32L4x that has been put in Shutdown and experiences a brown out or POR. it shows the correct flags after reset, but the same flags appear after subsequent Shutdown periods.

This is the sequence of events:Enter Shutdown with RTC Wake up timer enabled (5 seconds)Brown out, remove and restore powerPOR Reset occurs, correct PWR->CSR = 0x0C000600Clear CSR flags by writing 1 to RMVF in CSRRead CSR flags and confirm they are c...

UART - Data corruption due to noisy receive line

I found out in the errata of STM32G070 MCU (page: 12, section: 2.11.1) that: in UART mode with oversampling by 8 or 16 and with 1 or 2 stop bits, the received data may be corrupted if a glitch to zero shorter than the half-bit occurs on the receive l...
