That saves board space and one I²C or SPI bus slot — handy when you only have 25 GPIOs to work with. ## Lifecycle: EOL hot — plan the last buy now This part is flagged EOL hot, meaning ST has discontinued it and the last-time-buy window is closing or already closed. If you have an active BOM line that uses this MCU, secure your lifetime buy through the independent channel now. No official successor is listed in the record, so a pin-compatible drop-in from the STM32L0 series is not guaranteed — verify footprint and firmware compatibility before substituting.","metaTitle":"ST STM32L041K6U7 ARM Cortex-M0+ MCU, 32 MHz, 32 KB Flash","metaDescription":"STM32L041K6U7 32-bit MCU with 32 KB Flash, 8 KB RAM, 1 KB EEPROM, -40 to 105 °C.
