STM32L011K4T6 Description
The ultra-low power STM32L011x3/4 family of access lines integrates a high-performance ARM Cortex - M0Byte 32-bit RISC core running at 32 MHz, high-speed embedded memory (up to 16K bytes of flash program memory, 512 bytes of data EEPROM and 2K bytes of RAM), and a variety of enhanced Icano and peripherals. STM32L011x3/4 devices provide high energy efficiency for a variety of properties. It is realized through a variety of internal and external clock sources, internal voltage adaptation and several low power modes. STM32L011x3/4 devices provide a variety of analog functions, including a 12-bit ADC with hardware oversampling, two ultra-low power comparators, multiple timers, a low power timer (LPTIM), three general purpose 16-bit timers, a RTC and a SysTick that can be used as a time base. They also have two watchdogs, a watchdog with independent clock and window functions, and a window watchdog based on bus clock.
