Product details

Automotive 8-bit MCU with AEC-Q100 qualification and extended temperature range

The STM8AL3136UCY is an 8-bit MCU from the STM8A series, specifically qualified to AEC-Q100 and rated for the full -40°C to 125°C operating temperature range. It is designed for automotive body and chassis applications where a low-pin-count, low-power controller is sufficient — LIN slave nodes, smart actuator drivers, or sensor interface modules. The 16 MHz core speed, 8 KB Flash, and 2 KB RAM suit firmware footprints for dedicated control loops rather than complex protocol stacks.

The 1 KB EEPROM allows parameter storage without external memory, useful for calibration data or fault logs in a sealed module.

Frequently asked questions

What is the closest pin-compatible alternative to STM8AL3136UCY?

The STM8AL3Lxx family includes pin-compatible variants with higher Flash and RAM densities; a direct replacement within the same STM8A series would need to match the 32-VFQFN package and the same peripheral set. We can help identify the specific active order code that matches your firmware footprint and pinout — contact us with your BOM for a cross-reference.

What is the listed speed of STM8AL3136UCY?

The core runs at 16 MHz, which is the maximum clock frequency for this STM8A device.

What AEC-Q grade and temperature range does STM8AL3136UCY meet?

It is AEC-Q100 qualified and rated for -40°C to 125°C ambient operating temperature, suitable for under-hood and engine-bay environments.

What compliance documentation is available for STM8AL3136UCY?

Standard RoHS and REACH declarations are available. The AEC-Q100 qualification data (PPAP-level) should be on file from the original qualification; we can request it from the supply chain on your behalf.
