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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...

Hey guys,I am trying to communicate with S25FL064L Cypress Flash and almost for one week I cant reach the redec ID , I checked the hardware, and communication with digital analyzer just with S25FL064L no any hardware.Tried the HAL library , checked ...
On the STM32G071RB board, I tried to read the temperature using HAL-based conversion macros. At ambient temperature I get reading of 47 to 60 celsius depending on whether or not the HAL_ADCEx_Calibration_Start() is called to improve accuracy.The macr...
I am using the stm32g474rct6 RTC module. over a duration of 2 days, the drift was over 15 seconds. I tested it in standard room conditions. How can I solve this problem ?
