If your design lives in an engine control module, transmission controller, or body-domain node that sees under-hood heat, this grade is what keeps the firmware from glitching. The 2K x 8 EEPROM on-chip means calibration data, fault codes, or trim parameters stay put across power cycles without an external serial EEPROM — one less part on the BOM. ## 16 MHz — what it buys you on the bus 16 MHz is a moderate clock for an 8-bit core — plenty for LIN-bus gateway nodes, sensor readout loops, or segment-LCD updates. The DMA and PWM peripherals offload the CPU for motor-commutation timing or ADC scan sequences. With 41 I/Os in a 48-LQFP, you have headroom for a parallel LCD interface plus a few spare GPIOs for diagnostics. ## Sourcing this NRND part","metaTitle":"ST STM8AL3L88TCY 8-bit MCU, AEC-Q100, 64KB Flash, 16 MHz","metaDescription":"STM8AL3L88TCY NRND automotive MCU with 64KB Flash, 2KB EEPROM, -40 to 125°C.
