.The STM32L031G6U6S is a low-power microcontroller from STMicroelectronics with an ARM Cortex-M0+ core. It features an ARM Cortex-M0+ CPU with 32-Kbytes of on-chip Flash memory and 32 MHz performance. Peripherals such as GPIO, Timers, ADCs, and DBG provide extensive connectivity options. The design also offers an ultra-low-power power mode, which reduces the current consumption to just 5 µA/MHz. Low-power features such as low-power run, stop, standby, and hibernation modes are also available and help to further reduce power consumption during periods of inactivity. In addition, the STM32L031G6U6S Can be used in a wide variety of applications due to its wide range of dedicated peripherals. It also includes an additional backup domain to maintain information during power-down modes. It can be used on embedded devices such as IoT nodes, consumer electronics, motors, and home automation.
