The device features 16KB of Flash memory with ECC, 2KB of SRAM, and 512 bytes of data EEPROM with ECC. The ultra-low-power design achieves 0.23uA in Standby mode, 0.34uA in Stop mode, and only 79uA\/MHz in Run mode. The 5us wakeup time from Flash memory enables frequent sleep\/wake cycles. The integrated 12-bit ADC can convert at 1.14Msps with only 1uA at 10ksps. Two ultra-low-power comparators support window mode and wake-up capability down to 1.8V. Communication interfaces include USART, LPUART, SPI, and I2C.","working_principle":"The STM32L011K4U6TR is based on the Arm Cortex-M0+ processor implementing the ARMv6-M architecture with a 2-stage pipeline for optimal power efficiency at 0.95 DMIPS\/MHz. The power management system provides Sleep, Stop, and Standby modes. The internal voltage regulator adapts the core supply. The MSI RC oscillator provides 65kHz to 4.2MHz without external crystal, while HSI16 provides 16MHz +\/-1% accuracy. The PLL boosts system clock to 32MHz. The DMA controller offloads data transfers without CPU intervention.","pin_description":"
