STM32L011K4T6
Overview
The STM32L011K4T6 is an ultra-low-power microcontroller based on the high-performance Arm Cortex-M0+ 32-bit RISC core operating at 32 MHz. It features 16 Kbytes of Flash memory, 2 Kbytes of RAM, and 512 bytes of data EEPROM in a compact LQFP32 package. This device is specifically engineered for high efficiency in battery-operated applications through multiple power-saving modes and autonomous peripherals.
Why Choose This Part
The primary advantage is the industry-leading power consumption in active and sleep modes, featuring a high-efficiency Cortex-M0+ core. It includes a hardware RTC, multiple low-power timers, and an internal voltage reference that remains stable even when the supply voltage drops. This balance of performance and efficiency simplifies power supply design for compact IoT hardware.
Applications
