A comprehensive set of power-saving modes allows the design of low-power applications.\n\n Some independent power supplies are supported: analog independent supply input for ADC, DAC, OPAMP and comparators. A VBAT input allows to backup the RTC and backup registers.\n\n The STM32L431xx family offers nine packages from 32 to 100-pin packages.\n\n
