Automotive 8-bit MCU with integrated LCD and analog front-end
The STM8AL3189TCY: What sets this part apart in the 8-bit automotive space is the integrated LCD driver and the 28-channel 12-bit ADC plus dual 12-bit DAC — a combination that lets a single MCU handle both the analog sensor front-end and a direct-drive segment display, saving a companion CPLD or external converter.
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.
