STM32 MCUs Products

Hi. I boot with stm32L010C6Tx. I am in standby mode. While waiting in standby mode, it shows between 3.1 micro amps and 50 micro amps 50 microamps is too high, I can't use it like this. . I turned off all peripherals. What else should I turn off? Why coul

Trigger SPI Read using Timer Update Event

Hello,I am trying to trigger each DMA read of my SPI to happen on update event Trigger output of my Timer but I don't think I have it setup correctly.I've seen this done using the internal ADC, where you can set the external conversion trigger source...

Max voltage on pins when unpowered?

Hello,I notice in the STM32G030x6/x8 datasheet, Table 18 that the max input voltage on FT_xx and any other pin are VDD + 4V and 4V respectively. Does this mean those pins can be safely driven with 3.3V when the MCU is unpowered?Thanks,Nicholas

Incomplete HAL_DMA_Abort_IT() in STM32F7xx_HAL v1.16

Hello,During a UART transfer I used the HAL_DMA_Abort_IT() function. The transfer stopped but the DMA handle stays locked and in the HAL_DMA_STATE_ABORT. When in this state the only thing to do is reinitialize the peripheral.Anyone have some feed bac...

ADC on ST Nucleo H743ZI board with DMA on Zephyr platform.

Hai, I am working with ST Nucleo H743ZI board for analog-to-digital conversion without CPU intervention between samples, by using DMA in Zephyr platform. Is there any ready-made example for the above, that I can refer?Thank you. Sachin

I have question on STM32F777 RTC and super cap

I wanted to use RTC Circuit for Supercap.I have designed circuit (Check Attached snapshot).but i dont get back up time? can anyone explain do we need to do any provision in controller.It seems that capacitor is discharging very fast

Dear Support, Please help to check and confirm if the marking "7B594 9R" is lot number for the part number STM32G474VET6. Please refer to the photo below. Thanks
