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...

Hello,I'm a bit confused to how use the VREFBUF on this MCU.I want to use the internal voltage reference (SCALE 0 : 2.5V) for better ADC accuracy.Do I have to connect the VREF+ pin (20) to AVDD (+3.3V) or I've to connect it to a 1uF + 100nF capacitor...
Hi,I have a test app for the U5, which is intended to sleep for a short period of time and wake for a short period time, not unlike the default PCC Sequence you can see in the CubeIDE IOC. It will toggle an output line when entering STOP3 mode and al...
Hello, I have configured SPI Slave Receive only with Circular DMA, and I can receive data fine. My problem is that I want to have the current receive index on the SPI DMA Buffer when I receive an external interrupt I try to use StreamIndex but it sh...
Hi everyone,I'm a beginner, and this might be a basic question for many of you, but I appreciate your help nonetheless.I'm working on a project using the STM32H723VGH6 (due to size and design constraints, I can't use the ZG series) and I want to expa...
I am using a pin to Switch on the power supply once the MCU is powered.When powering up the MCU I am getting a Glitch before it turns on the MC GPIO configuaration is given below. For every output I am getting a glich before it SET from RESET Can a...
Hi,I have enabled option bit SRAMxECC is in FLASH_OPTR by following sequence mentioned in datasheet to enable SRAM ECC, However RAMCFG_MxCR ECCE still shows as 0(disabled). Please do the needuful.
Hi,I want to use BC1.2 protocol of STM32G473CE MCU. But STM32G473CE supports USB PD also. So in order to use only BC1.2 can I use only Dp Dm lines of STM32G473CE and leave CC lines un-connectedAlso what is the maximum power negotiation performed by S...
I'm trying to set the QUADSPI FIFO threshold when reading from external flash using interrupts and I want an interrupt to occur when there are 32 valid bytes in the FIFO. I'm setting the QUADSPI_CR_FTHRES to 31 according to the datasheet but when I l...
Hi all! I have been using a F446RE board to communicate with an encoder using SPI. I get back a 16-bit value every ms (the process runs at 1kHz). However, I now need to transfer the acquired data over ethernet (it has to be ethernet, not UART or anot...
