STM32L031G6U6TR

STM32L031G6U6TR is an ultra-low-power Arm Cortex-M0+ MCU. It incorporates the high-performance Arm® Cortex®-M0+ 32bit RISC core operating at a 32MHz frequency, high-speed embedded memories plus an extensive range of enhanced I/Os and peripherals. This device provides high power efficiency for a wide range of performance. It is achieved with a large choice of internal and external clock sources, an internal voltage adaptation and several low-power modes. It offers several analog features, one 12bit ADC with hardware oversampling, two ultra-low-power comparators, several timers, one low-power timer (LPTIM), three general-purpose 16bit timers, one RTC and one SysTick which can be used as timebases. It is used in applications such as gas/water meters and industrial sensors, healthcare and fitness equipment, remote control and user interface, PC peripherals, gaming, GPS equipment, alarm system, wired and wireless sensors, video intercom.
