Can I pull Vref- lower then Vss [stm32C5]

Hello,Is it possible to pull Vref- lower then Vss? For reverse voltage protrection I use a diode and a resistor to create GND1. GND1 is then connected to VSS of the µC.Scematic. All caps omittedCan I connect Vref- to GND? See Image.Datasheet stm32c54

STM32H755 DMA peripheral read timing differs from AN4031, actual hold time shorter, seeking explanation

Hello,I have recently tested the timing of DMA reading data from GPIO on an STM32H755 and found that the required input signal hold time is shorter than what is described in AN4031. I would like to ask whether my understanding is incorrect or if it i

STM32H743VIT6 – Is VBAT required for normal MCU operation when VDD is always present?

Hello ST Support,I am using an STM32H743VIT6 on a custom PCB. The PCB has already been fabricated, and I discovered that the VBAT pin is left unconnected (floating).My application does not use RTC, LSE, backup registers, backup SRAM, or battery backu

STM32N6 Nucleo XIP clock frequency problem.

Hello everyone,I’m using Nucleo STM32N6 for a project of mine, and I used template XIP to begin with.In template XIP, clock frequency of the XSPI2 is set to 50Mhz without any prescalers, and VDDIO3 is set to 1 (1.8V). That setup works fine for XIP up

HardFaults from a CS4270 I2C driver

Hi All,So I have an STM32F469 on a PCB I’ve designed with a CS4270 audio codec. I am currently working on an I2C driver to initialize the codec (I am using code from Phil’s lab’s video on writing an I2C driver for the CS4270 - video here), however I
