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...
Posted on December 08, 2015 at 08:56Hello, in one of the projects my device regulary goes to standby and I need a place to buffer the data. Since the F4 series do not have so many small sectors and the program already takes over the first 4 smallest...
Posted on November 07, 2015 at 15:11Hello, Why only 64Mbit are accessible on the board ? Why the board was not designed with 16bit-wide SDRAM ?
