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...
