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...
Posted on January 31, 2018 at 09:21Hello, that's the SRAM of STM32H7x3 microcontroller. I need to receive over 800 kib of data on high speed and place it in RAM via DMA. I read that there's 864 kib of ram here but I was confused to find out that it'...
Posted on January 31, 2018 at 02:48Hello, I have a separate MCU acting as the SPI Master, sending data in multiples of 64 bytes (anywhere from 1x 64 byte group, to 10x 64 byte groups) - all during a single transaction. So NSS goes low, 64 bytes to 6...

Posted on January 30, 2018 at 17:54Hi, we are sleeping the STM32F072xB using PWR_EnterSTOPMode() and waking on various GPIO for button press, etc. Is it possible to wake on a USB message? Is there an app note or example on this? Does anybody know...
Posted on January 30, 2018 at 17:48Hi, we sleep the STM32F072xB using PWR_EnterSTOPMode() and currently wake from some GPIO like button press. We do have a USB connection up and I'm wondering if the other side could wake us with a USB message. Is ...
