The 54 I/O lines give enough headroom for a segment LCD, a few LIN transceivers, and local sensor inputs.","metaTitle":"ST STM8AL3189TCX 8-bit MCU, AEC-Q100, 64KB Flash, 16MHz","metaDescription":"STM8AL3189TCX automotive 8-bit MCU with 64KB Flash, 4K RAM, 2K EEPROM, 12-bit ADC/DAC, LIN, LCD driver.
