I am using the STMG0B1RET on a custom, battery-powered board. During normal operation pin PC4 is used as UART1 (with an external pull-up resistor). In Standby Mode pin PC4 must be LOW in order to shut down the external device. For this I convert PC4 ...

I am using this MCU on a battery-supplied custom board: STM32G0B1RET.I am looking for clarification re. the GPIO availability in Standby Mode.Table 26 in Reference Manual RM0444 (see below) seems to offer one of two (exclusive) possibilities:Without ...

Hello, this is my equipment: 1) MCU STM32G0B1RETx (LQFP64 packaging) on a custom board.2) STM32CubeIDE Version: 1.17.0.3) STM32CubeMX Version 6.13.0.For visual indicators (LEDs flashing) we use the TIM4 CH1 in OC Toggle mode (no output). The timer co...

Hello, the STM32G0 low-power state diagram (Figure 8 below) is in the ref. manual RM0444 on page 127.It shows that a direct transition from Run Mode to LP Sleep Mode is not possible.Questions:* Is there a simple method to transition from Run Mode to ...

Question about the above PWR_LPSLEEP example code.My test setup includes this:* STM32CubeIDE Version: 1.17.0, Build: 23558_20241125_2245 (UTC).* HAL library STM32Cube_FW_G0_V1.6.2.* NUCLEO-G0B1RE.The example code in main() reduces the clock frequency...

I have the same issue with STM32CubeIDE 1.18.00. Instead of using an older GCC version, is there a 'more future proof solution'?

Hello @ZZH, I trust that your issue is resolved by now.Your post suggests that you can successfully put the STM32G0 into Standby Mode. I have difficulties with that, and posted about it (STMG0B1RET output pin does not pull down in Standby Mode) and s...

Hello @Piranha, thank you fI or posting your solution. We are experiencing have the That is exactly the problem we experience with the STM32G0B1RET MCU:During normal operation pin PC4 is used in a UART1 configuration (with an external pull-up resist...

@TDK, just for clarification re. the STM32G0B1RET on a battery-supplied custom board: the datasheet states that the pull-down resistor is weak, Table 55 lists around 40kOhm (see below). Can that cause a problem in Standby mode?Also, one member state...
