Product details

Automotive 8-bit MCU with 16 MHz core and 32 KB Flash

NRND status — what it means for procurement

The laser etch and date-code traceability on each reel is verified before shipment.

AEC-Q100 qualification and 125°C operation

This means the MCU is characterized for Grade 1 automotive applications — engine control, transmission, braking systems, and other under-hood modules where silicon must survive thermal cycling and vibration.

Peripheral set and 12-bit ADC array

The DMA controller offloads data movement from the core, useful for sensor acquisition loops.

Frequently asked questions

Is STM8AL3168TCX obsolete?

It is not fully discontinued, but new designs should use the recommended replacement. Existing production can continue sourcing through independent distribution; we verify date-code consistency and lot traceability on each reel.

Does STM8AL3168TCX have an automotive qualification?

This covers under-hood and cabin automotive electronics, as well as industrial environments requiring extended temperature range.

Is STM8AL3168TCX compatible with STM8A development tools?

Yes, the STM8AL3168TCX uses the standard STM8 core and is supported by ST's ST Visual Develop (STVD) IDE, the Cosmic and IAR toolchains, and the ST-Link debugger/programmer. The SWIM debug interface is accessible on the 48-LQFP package.

Is STM8AL3168TCX RoHS compliant?

ST's STM8A series is generally RoHS-compliant; the specific compliance status for this order code should be confirmed at quote time, as the manufacturer's PCN history applies.
