It runs at 16 MHz with 16 KB of Flash program memory, 2K x 8 RAM, and 1K x 8 EEPROM — enough for body-control modules, sensor hubs, and actuator interfaces where a small-footprint 8-bit controller with deterministic timing is the right fit. The 32-LQFP package (7x7 mm) packs 29 I/O lines, with an integrated 21-channel 12-bit ADC and a single 12-bit DAC that reduce external analog front-end components. ## 16 MHz core — enough for the task, not a speed race The 16 MHz clock on this STM8 core delivers deterministic single-cycle instruction execution for the majority of ALU operations. That places it in the sweet spot for automotive body electronics — window lift, seat adjustment, ambient lighting, and wiper control — where the control loop is dominated by sensor acquisition and CAN/LIN messaging, not number-crunching. The integrated peripherals (DMA, multiple timers, PWM, brown-out detect) mean a single-chip solution for most mixed-signal body-domain tasks without an external supervisor or ADC.","metaTitle":"ST STM8AL3L46TCY 8-bit MCU, 16 MHz, AEC-Q100, 32-LQFP","metaDescription":"STM8AL3L46TCY is an NRND automotive 8-bit MCU from STMicroelectronics, 16 MHz, 16 KB Flash, 2K RAM, AEC-Q100, -40 to 125°C.
