Key Features
- AEC-Q100 automotive qualification ensures reliability across the -40°C to +125°C temperature range for in-vehicle designs
- 32 KB Flash plus data EEPROM with integrated LIN interface simplifies single-chip body-electronics node implementation
- Ultra-low-power modes with fast wake-up enable battery-backed RTC and standby operation well below 1 µA
Applications
The STM8AL3166TAY targets automotive body-control modules, LIN slave nodes, and smart-actuator controllers that require AEC-Q100-qualified 8-bit processing with minimal power draw. Its integrated LIN transceiver, RTC, and 32 KB Flash make it suitable for window-lift controllers, seat-position memories, and HVAC flap drivers. The device also fits industrial low-power sensor nodes where a 16 MHz 8-bit core with on-chip ADC and DAC reduces external component count.

Frequently Asked Questions
What Flash and EEPROM memory does the STM8AL3166TAY provide for automotive firmware storage?
The STM8AL3166TAY integrates 32 KB of Flash program memory and a dedicated data EEPROM, giving designers non-volatile storage for both firmware and configuration parameters without an external EEPROM device. At a maximum clock frequency of 16 MHz, the 8-bit STM8 core can execute code directly from Flash with zero wait states at low supply voltages.
Which automotive qualification standard applies to the STM8AL3166TAY, and what is its operating temperature range?
The STM8AL3166TAY is qualified to AEC-Q100 Grade 1, covering a junction temperature range of -40°C to +125°C. This makes it suitable for under-hood and interior automotive environments where thermal stress from engine heat or solar loading would exceed the limits of commercial-grade microcontrollers.
How does the integrated LIN interface on the STM8AL3166TAY reduce BOM cost in body-electronics designs?
The on-chip LIN-capable USART allows the STM8AL3166TAY to act as a LIN 2.x slave node without an external LIN transceiver IC in many low-speed applications, saving at least one component and associated decoupling capacitors. Combined with the 32 KB Flash and 16 MHz clock, a single 32-pin QFP device can handle protocol decoding, PWM dimming, and ADC-based position sensing for a window-lift module.
What analog peripherals are available on the STM8AL3166TAY for sensor interfacing?
The device includes a multi-channel ADC and at least 1 DAC channel, along with analog comparators (COMPs), enabling direct connection to resistive sensors, NTC thermistors, and analog position sensors without external signal-conditioning ICs. The ADC resolution and DMA channel support allow background sample collection at 16 MHz without stalling the CPU.
