STM32G0 RAM backup buffer
Dear ST,For the implementation of many security mechanisms (e.g., the MARCH C algorithm), the use of a RAM backup buffer is proposed. However, I can't find a RAM backup buffer in the STM32G0 family datasheet. I also can't find the SRAM Backup option ...
H7 power dissipation and lifetime, how to manage?
Hello,I came across this document here https://www.st.com/resource/en/application_note/dm00622045-stm32h7-series-lifetime-estimates-stmicroelectronics.pdfWe have a H75x custom board running the MCU in VOS1 at 400MHz with external 1.2V core power supp...
Resolved! Sleep, stop and standby modes do not significantly reduce current consumption
Greetings, I'm having an issue with low-power modes. I'm using a STM32U585 MCU and while in run mode it is consuming around 100mA, which is a lot. I tried to enter in Sleep, Stop and Standby modes right after the main declaration:int main(void) { ...
Parsing UID Fields on STM32L476 – Wafer X/Y Coordinates and BCD Encoding?
Hi everyone,I’m working with an STM32L476 and need to parse its 96-bit Unique Device ID (UID).According to RM0351, the UID starts at address 0x1FFF 7590.Reading that region with STM32CubeProgrammer gives:• 0x1FFF 7590 : 0x004A0029• 0x1FFF 7594 : 0x58...
