I am currently working on a new hardware design using the STM32U575VIT6 (LQFP64, 10 × 10 mm) microcontroller.I would like to request:Reference schematics and layout guidelines for STM32U575 in LQFP64 packageRecommended power supply and decoupling cap...
Hi ST, I'm looking for STM32 boards that are permitted for end-product usage. In particular, I find Nucleo wonderful but my understanding is they are not to be distributed in the product. Does ST offer any comparable SBCs to Nucleo that can be essent...
I have an STM32L4R on a custom PCB. I am able to flash firmware using CubeProgrammer/CubeIDE to it via an ST-LINK SWD connection as well as a DFU Bootloader via a USB D connector. I have a makeshift connection between the USB D connector to a USB C c...
I have configured WWDG Timer in CM7 of Stm32H747I-Disco and configured WW1RSC=0 in RCC global control register (RCC_GCR) for CM7 Reset only instead of system reset.Issue:HAL_WWDG_EarlyWakeupCallback is getting called before watchdog Reset. but afrer ...

Hi, Please suggest STM32L562 UFBGA-132 Fanout guidelines.I looked into STM32L562E-DK design files for fanout, in which signals are routed in top and S1 layer but there is not via details for layer transition from top to S1. Here attached the fanout f...
Hi everyone, I’m trying to use the STLINK-V3MODS Bridge GPIOs (GPIO0–GPIO3) as digital outputs, but none of them show any voltage change at the pins — not even in Open-Drain mode with an external pull-up. All API calls (InitGPIO / SetResetGPIO / Read...
I purchased a Nucleo-L476RG eval board and downloaded the PWR STOP2 RTC example code to test for a low power application.After following the instructions for the jumper settings outlined in UM1724 for external power, I built and tried the example. Th...
