STMicroelectronics STM32L011K4 - Ultra-low-power ARM Cortex-M0+ MCU

The access line ultra-low-power STM32L011xx family incorporates the high-performance ARM® Cortex®-M0+ 32-bit RISC core operating at a 32 MHz, high-speed embedded memories (up to 16 Kbytes of Flash program memory, 512 bytes of data EEPROM and 2 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals. It offers one 12-bit ADC with hardware oversampling, two ultra-low-power comparators, several timers, one low-power timer (LPTIM), three general-purpose 16-bit timers, one RTC and one SysTick which can be used as timebases. Moreover, the devices embed standard and advanced communication interfaces.

The STM32L011xx also include a real-time clock and a set of backup registers that remain powered in Standby mode. The ultra-low-power STM32L011xx devices operate from a 1.8 to 3.6 V power supply (down to 1.65 V at power down) and are available in the -40 to +125 °C temperature range. A comprehensive set of power-saving modes allows the design of low-power applications.
