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 07, 2012 at 06:09Hi,I am curious as to what the '50MHz' output speed of the GPIO ports refers to (with correct configuration bits set). Is it the maximum frequency of a square wave output, or does it have something to do with the r...
Posted on January 10, 2012 at 18:19Hi folks! I'm working with STM3210E_EVAL and uCLinux. For one week i have tried to activate the SD Card in this board, but no success =( I compiled the kernel with MMC support and tried to edit the device.tab file...
Posted on January 10, 2012 at 17:22 I'm trying to do something really simple, take the STM32L discovery, put some code in it and measure the current across JP1 (in the off position as the manual suggests).... However, I can't seem to get down to...
Posted on October 09, 2011 at 18:32Hello everybody, Potential new user of ST chips here, feeling somewhat silly for asking this. However: Is the information provided by Atollic in their feature comparison document, v2.2, accurate? I am in particular...
