The peripheral set is built for automotive body electronics: a 28-channel 12-bit ADC and dual 12-bit DAC handle analog sensor conditioning and gauge drive directly, while the integrated LCD driver, LINbus, and SPI/I²C interfaces reduce external glue logic.
The 54 I/O lines give enough headroom for a segment LCD, a few LIN transceivers, and local sensor inputs.
No official pin-compatible replacement order code is listed in the manufacturer record. For new designs, evaluate the current STM8A automotive portfolio from STMicroelectronics, which shares the same core and peripheral architecture.
Yes, it is part of the Automotive, AEC-Q100, STM8A series, qualified for automotive-grade applications across the -40°C to 125°C temperature range.
The core runs at 16 MHz, which is sufficient for LIN-based body control and instrument-cluster update rates in an 8-bit architecture.
The datasheet is available from STMicroelectronics under the base product number STM8. The full PDF covers the STM8A family electrical characteristics, memory map, and peripheral register descriptions.
