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...
no distributor nor STM's eshop has any STM32-device."Out of stock" or "on allocation".Why shall we waste any further development time on STM32 when there are no chips available?So, is STM32 dead?In my opinion, STM32 is dead.Currently any other experi...

Hi Everyone,I am using stm32l073rz board, used both wakeup pin PWR_CSR_EWUP1 (PA0) and PWR_CSR_EWUP2 (PC13) for generating an interrupt to wakeup from standby mode, and I am enable both pin PWR->CSR |= (PWR_CSR_EWUP1 | PWR_CSR_EWUP2); before go to st...
I've got a "K9F1G08U0E" nand flash. I was trying to understand how to use the generated ECC in the STM32 MCU "ECCx register" to check the validity of data received from the NAND flash. but in the documentation there is no explanation on how to use th...
Good day to everyone on this forumI was working on a code, my borad is a Nucleo-144 STM32F746, At first I was trying to read 12 Analog signals, from 0 to 3V with DMA and the reads were good exept for some channels with noise and a weird offset, I red...
Hi,we have a strange behaviour which could be resolved by changing clock configuration, but we cannot explain why the errors occured in the first place. Perhaps some of you have any idea why the following happened:random hardfault during runtime afte...
In RM0091 rev.9, footnote 2 to Figure 273 on Page 760 has the following text:All the events associated with the transmitter receive flow must be ignored in standard transmit only mode (e.g. OVF flag).There is no OVF flag in the 'F0xx SPI; this shoul...
Hello,I have developed a device using an STM32F4 but am now trying to either add BLE or merge to an SoC with BLE and don't know the easiest path forward. I need OOB pairing using NFC but am very limited in PCB space.Does ST provide an all in one SoC...
Hello,Does anybody know if there is any prerequisite when enabling or disabling the prefetch buffer?More specifically, in the Nucleo L4R5ZI sleep example the prefetch buffer is disabled in main() just before the main loop. It is never re-enabled afte...
