Why STM32H745xxx can't run at 480Mhz when the core is supplied by internal SMPS directly?
The SMPS output voltage can reach 1.8V . That is upper than 1.7V requested.

LPTIM to put my STM32L0 device in sleep for 200 ms
Hi all,I would like to use LPTIM in STM32L0 to put my device in sleep mode for 200 ms. I have used the API HAL_LPTIM_TIMEOUT_START(LPTIM_HandleTypeDef * hlptim, uint32_t Period, uint32_tTimeout), I pass 200 as value for both Period and Timeout.I use ...
Determine flash page size at run-time
STM32G4 devices are split into 2 flash categories per the datasheet: Category 2 devices (STM32G43x/G44x) which have only single-bank capable flash with a capacity up to 128kB and Category 3 devices which are dual-bank capable and have up to 512kB of ...
STM32H747 generate code issue with STM32Cube and Keil
I have tried to generate STM32H747I-DISCO's GPIO code.After loading flash, it can be executed normally.But after power on the MCU, the code can't be executed and the MCU can't be target with ST-link.I must pull-up boot0 and erase flash before I can r...
When I debug in serial wire mode, can I use the NJTRST pin as a reset pin?
When I debug in serial wire mode, can I use the NJTRST pin as a reset pin?Because I do n’t want to lead the chip NRST pin.
