Resolved! STM32H743 5V tolerant pins for an LQFP176 Package

Hello, I have a doubt about the voltage tolerance of STM32H743: looking at Stm32h743bi.pdf, LQFP176 pins are numbered 1,2,...,176, while CubeIDE gives me PA1, PA2, PB1, PB2.... etc.So, how can know if my UART3 pins (PB10 & PB11, Alternate function P...

Resolved! Hello everyone, I have to implement SMBus communication with battery. I read X-CUBE-SMBUS Software is only compatible with NUCLEO-G431RB, NUCLEOH743ZI, NUCLEO-L4R5ZI, 32F072BDISCOVERY, 32L0538DISCOVERY, 32L476GDISCOVERY, and STM32F3DISCOVERY boards.

I have an STM32 F401RE (NUCLEO - 64)board. In the document " Description of STM32F4 HAL and low-layer drivers" there are HAL SMBUS Generic drivers. Is it possible to implement SMbus communication using this board or I will have to purchase on of the ...

Resolved! Problem with STM32h755, when expanding the accessed RAM area by Cortex M7 core, the program crashes.....

Hi every body! I chose STM32H755ZI MCU mainly because it has 1MB of RAM. In my project, I need to at least store 180 KB of Data. 45000 of float samples. I use the M7 Core which accesses the AXI RAM the size of which is 512KB; on the other hand, the B...

Resolved! STM32H753ZIT6 vs STM32H753ZIT6U

Hi,What is the difference between STM32H753ZIT6 vs STM32H753ZIT6U?I am curious because the U variant is on the eval card, but is not available anywhere. The non-U variant seems to have replaced it from all vendors.
