STM32L051K6U6 Description

The high-performance Arm Cortex-M0+ 32-bit RISC core, operating at a 32 MHz frequency, a memory protection unit (MPU), high-speed embedded memories (64 Kbytes of Flash program memory, 2 Kbytes of data EEPROM, and 8 Kbytes of RAM), as well as a wide variety of enhanced I/Os and peripherals, are all included in the access line ultra-low-power STM32L051x6/8 microcontrollers.

High power efficiency is offered by the STM32L051x6/8 devices for a variety of performance. A wide variety of internal and external clock sources, an internal voltage adaption, and numerous low-power modes are used to achieve it.

The STM32L051x6/8 devices have a variety of analog capabilities, 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 basic timer, one RTC, and one SysTick that can be used as a timebase. Additionally, they have two watchdogs: one with independent clock and window functionality and the other with a window watchdog based on a bus clock.
