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...

If this device is powered-down (i..e voltage is 0 on all rails), what impedance will be presented by the Port pins? If a pin from a powered-down STM32H743 is connected to a pin on another (fully powered) device, what current drain will occur?
In Section 2.2.13 of ES0392, it states that there is "unexpected leakage current" if Vin >Vdd.What is the bound on the leakage current (assume an FT pin type):Vin = 5V and Vdd = 1.8VVin = 5V and Vdd = 3.3VVin = 3.3V and Vdd = 1.8VThank you.
After causing a watchdog reset RCC->RSR is showing as 0. I didn't think that was a valid value unless a jump was performed. I check RSR first thing so nothing should be clearing the bits by setting RMVF bit. Other types of reset seem to work. I haven...
Hello dear experts,I am using the TIMER2 on stm32F446Re with TI1_ED as reset mode input and TIM2_CH4 as timer value capture input. I inserted code to toggle a gpio in the HAL_TIM_IC_callback. On the scope I am capturating the TIM2_IC4 signal and the ...
I've got an application where I'm performing an ADC DMA transfer where the ADC conversions are triggered by the TIM2 TRGO. Everything was running smoothly until a PCB respin forced me to switch over to TIM21 to trigger the conversion. I didn't see a ...
I am using STM32F746NG(DISCO_F746NG) with camera(STM32F4DIS-CAM) to capture images by using https://os.mbed.com/teams/ST/code/BSP_DISCO_F746NG//file/85dbcff443aa/ this driver.Currently this camera gives image in RGB565 format ans we are converting it...
HI, we are working on STM32H750. in our program, we need to store 5 bytes in the internal flash. this data will be read everytime the device is powered on. the data will be changed whenever the settings are changed by the user. i.e. once in a while.M...
Hi,I created this function in order to store the date and time. It works !But the problem is when I load date and time, the time is the last before turning off the system.void RTC_Init(void) { /* Restore the date form backup registers */ RTC_LoadDa...
