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 November 05, 2014 at 12:11Hi everyone! I have a project where necessary to use FPU to proccess my AD data. If I enable the FPU in the uVision Keil, then I can see an extra noise on my power line and I get wrong values, but when I disable ...
Posted on November 04, 2014 at 13:17I have problem when underclocking STM32F030. When I setup to RCC->CFGR2 higher value than RCC_CFGR2_PREDIV1_DIV4 (for example DIV5 - DIV16) then PLL is never ready ( RCC_CR_PLLRDY ) With value <= RCC_CFGR2_PRE...
Posted on November 05, 2014 at 14:27Hi guys, i have some problems with power consumption, i will try to describe my situation: MCU is assembed od PCB just with power supply and SWD interface, any IO is connected. Board is powered from lab. power sup...
