STMicroelectronics, 32 bit ARM Cortex M0+, STM32L011F4 Microcontroller, 32 MHz, 16kB FLASH, 20-Pin TSSOP

The STM32L011xx devices provide 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.

The STM32L011xx devices offer several Analogue features, 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. They also feature two watchdogs, one watchdog with independent clock and window capability and one window watchdog based on bus clock.
