For a BOM already using this MCU, the NRND flag signals that a last-time-buy window or eventual discontinuation may follow. ## 16 MHz core — throughput for control loops The 16 MHz clock rate is the ceiling for this 8-bit STM8 core. It delivers enough throughput for real-time sensor acquisition and actuator control in automotive body electronics, LIN node controllers, and DC motor drivers. The 12-bit ADC at 25 channels can sample multiple analog inputs without an external mux, reducing BOM count.","metaTitle":"ST STM8AL3188TCX 8-bit MCU, 64KB Flash, 16MHz, AEC-Q100, NRND","metaDescription":"STM8AL3188TCX 8-bit automotive MCU, 16MHz, 64KB Flash, 4K RAM, 2K EEPROM, -40°C to 125°C, AEC-Q100.
