STM32L051K6 Description
The access line ultra-low-power STM32L051K6 microcontroller incorporates 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) plus an extensive range of enhanced I/Os and peripherals. STM32L051K6 Microcontroller provides high power efficiency for a wide range of performance. STMicroelectronics STM32L051K6 Microcontroller is achieved with a wide choice of internal and external clock sources, an internal voltage adaptation, and several low-power modes.
STM32L051K6 MCU chip offers several analog features, one 12-bit ADC with hardware oversampling, two ultra-low-power comparators, several timers, and one low-power timer (LPTIM), three general-purpose 16-bit timers, and one basic timer, one RTC and one SysTick which can be used as timebases. STM32L051K6 Microcontroller features two watchdogs, one watchdog with independent clock and window capability, and one window watchdog based on a bus clock.
