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 April 12, 2016 at 08:56We're using the STM32CubeExpansion_BLE1_V2.5.2 on a STM32L4-Nucleo + BlueNRG-Expansion. It comes with low power manager drivers. The STM32L4 switches between RUN and STOP mode every ~ 1 sec. It uses RTC wakeup timer ...
Posted on April 09, 2016 at 22:47I'm designing a product that uses the STM32F446. The reference manual states that Vcap is increased to 4.7uF (from 2.2uF for the F405) on page 15 and later on page 72 (power supply scheme) it lists 2 x 2.2uF caps on ...
