ST is not actively soliciting new design wins for this order code. ## Peripheral set for instrument-cluster and body-electronics designs Connectivity covers the automotive LIN bus, SPI, I2C, IrDA, and UART/USART — enough for a cluster talking to a CAN gateway over LIN, or a door module communicating with a central body controller. DMA is available for ADC scan sequences and UART transfers without CPU intervention — useful for keeping the core asleep longer in low-power modes. ## Package, temperature, and qualification AEC-Q100 qualification covers stress tests for under-hood and cabin electronics. The 1.65 V minimum supply supports cold-crank scenarios.","metaTitle":"ST STM8AL3189TCY 8-bit MCU, 16MHz, 64KB Flash, AEC-Q100","metaDescription":"STMicroelectronics STM8AL3189TCY 8-bit automotive MCU, 16MHz STM8 core, 64KB Flash, 4Kx8 RAM, 2Kx8 EEPROM, AEC-Q100, -40°C to 125°C.
