New possibilities for the ultra-low power segment!

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...


Resolved! Temperature sensor characteristics of STM32F407

As per table 69 under section 5.3.22 of datasheet STM32F405XX/407XX (DocID022152 Rev 8), the parameters of “Average slope�? (Avg_Slope) and “Voltage at 25°C�? are specified to be 2.5mV/°C and 0.76V, respectively. Does it imply the sensitivity to be 4...
