What the STM32L010F4 does
The STM32L010F4 and STM32L010K4 are value line ultra-low-power 32-bit microcontrollers based on the Arm Cortex-M0+ core. These devices feature 16-Kbyte Flash memory, 2-Kbyte SRAM, and 128-byte EEPROM. They operate on a 1.8 V to 3.6 V supply across a -40 to 85°C temperature range. Key specifications include 0.23µA standby current, 0.29µA stop mode current, and a 12-bit ADC running at 1.14Msps. The part family supports up to 26 fast I/Os and includes seven timers, five DMA channels, and interfaces for SPI, I2C, and USART. Engineers typically use these microcontrollers in battery-powered applications requiring extended runtime and minimal power consumption.
