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...
In section 16.3.7 of STM32U5 RM0456 Rev 2, the following text appears in the bullet that notes MSIK, HSI and LSI are linked to TIM2/TIM3/TIM4/TIM5:"External clock mode1: Table 446: Interconnect to the tim_ti1 input multiplexer for TIM5, tim_ti1_in1 (...
Hi!I have a problem with the simultaneous use of an SD card (with SDIO) and the uart port with GSM module connected. The SD card works flawlessly all the time. Communication with the GSM module is very unstable when I use the SD card - using the f_mo...

Hiso I am trying to get the UART2 on my STM32G031K8Tx up and running. RefManual shows in Chapter 5.4.21 a CCIPR register (Peripherals independent clock configuration register), where bits 2-3 relate to the USART2.When looking at the device specific h...

Hello,I am trying to trigger each DMA read of my SPI to happen on update event Trigger output of my Timer but I don't think I have it setup correctly.I've seen this done using the internal ADC, where you can set the external conversion trigger source...
RM0444 Rev 5 Page 377 says • TS_CAL2 is the temperature sensor calibration value acquired at TS_CAL2_TEMP(refer to the datasheet for TS_CAL2 value)• TS_CAL1 is the temperature sensor calibration value acquired at TS_CAL1_TEMP(refer to the datasheet f...
Hello,I notice in the STM32G030x6/x8 datasheet, Table 18 that the max input voltage on FT_xx and any other pin are VDD + 4V and 4V respectively. Does this mean those pins can be safely driven with 3.3V when the MCU is unpowered?Thanks,Nicholas
As indicated by an4759, I am trying to use the 50Hz mains reference to improve the RTC accuracy of an STM32F413ZH.However, the results I get are much worse than without using the reference:LSE only: 0.6s/dayLSE+50Hz: 7.5s/day (test duration 4 days)Ac...
