The 1 KB of EEPROM is useful for calibration constants and fault-log storage without wearing the Flash. ## Analog and connectivity: sensor interface in one chip The connectivity set includes I²C, SPI, LIN, and UART, covering the common automotive serial buses. The 41 GPIOs provide enough headroom for a mixed digital/analogue interface to a small ECU. ## NRND status: plan the last-time-buy window The part is available for existing production but not for new design wins. Secure a last-time-buy quantity through independent distribution.","metaTitle":"ST STM8AL3L48TCY 8-bit MCU, 16 MHz, AEC-Q100, 48-LQFP","metaDescription":"STMicroelectronics STM8AL3L48TCY 8-bit MCU with 16 MHz core, 16 KB Flash, 2 KB RAM, AEC-Q100 qualified, -40°C to 125°C.
