STM32L031G6U6TR Description

High power efficiency is offered by the STM32L031x4/6 devices for a variety of performance. A wide variety of internal and external clock sources, an internal voltage adaption, and numerous low-power modes are used to achieve it.

The STM32L031x4/6 devices include a variety of analog functions, including a 12-bit ADC with hardware oversampling, two comparators that consume extremely little power, multiple timers, a low-power timer (LPTIM), three 16-bit general-purpose timers, an RTC, and a SysTick that can serve as a timebase. They also have two watchdogs: a window watchdog based on bus clock and a watchdog with separate clock and window functionality.

The STM32L031x4/6 devices also have I2C, SPI, USART, and a low-power UART as standard and advanced communication interfaces (LPUART).
