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 21, 2011 at 18:54Hi We have an odd problem. We have a custom F205RBT6 based board. It can be powered through separate 5V pins or USB. The 5V goes to a 800mA linear regulator which then provides 3.3V to the F205. We have an extra l...
