STM32 MCUs Products

What happens when GPIO is sourcing more mA than allowed?

My STM32F746 can source 25 mA per pin, but only 120 mA in total.What happens if we exceed that amount? Will there be a brown out, will the STM32 reset, or will the STM32 get damaged?

STM32H753 writing option bytes stalls execution

Hi,We are using an STM32H753 (revision V) and using the bank swap functionality to implement a firmware update system. To do this we need to write to the option bytes to toggle the bank swap bit.This process works but we have noticed that when the cu...

Hi, I have a brend new STM32L652 with tehe latest CubeIDE. When I try to program the MCU, the program seams to be loaded to the MCU but unfortunately I cannot debug it like I use to for other boards like NUCLEO. Do I have to configure something ? TY

hello everyones. i am working with sim7600 4G LTE module with usart port, but speed is slow. i want use high speed protocol such as usb or wlan with max supported speed that defined for 4G module. is anyone exist that work in this erea and help me?

Does remap of CAN1 pins work on STM32-E407?

I bought a few Olimex STM32-E407 boards lately. I need to use the CAN1 bus. However, the default PA11, and PA12 have not populated, and I remapped to PD0 and PD1. The code always failed immediately at CAN_init (generated by STM32CubeMX). No choice, I...

TIM2 DMA PWM to PA2 get no effect

my type is stm32f031c6. i used TIM2_CH3 binding to DMA1_Channel1 , and set in PWM1_MODE.i find the PA2 no AFIO register to remapping function. the PA2 gotta no PWM pulse.

Could the STM32F103 or STM32F412 support 4GB eMMC nand flash?

Our project want to use the 4GB eMMC NAND Flash on STM32F103RC or STM32F412VE.The eMMC architecture of NAND flash support revision , below. It just require to over the MMC standard 4.41 / 5.1.Could the STM32F103RC or STM32F412VE support 4GB eMMC NAND...

Read 6 waveform frequencies with stm32f103c8t, along with analog DMA reads and serial TTL communication

Hi I'm having an issue while reading 6 inputs each one with one waveform at the same time I'm collecting analog inputs and sending to TTL and reading settings from TTL.At some point if any of the wave inputs gets 119 Khz or more, the stm32 becomes u...
