Frequently asked questions
What is the closest pin-compatible alternative to the STM8AL3146TAY?
ST does not publish an official pin-compatible replacement for the STM8AL3146TAY under its NRND status. The STM8A family includes higher-density siblings (e.g., 64 KB Flash variants) that share the same 32-LQFP footprint, but verify pin compatibility against the datasheet's ordering information before substituting.
What is the STM8AL3146TAY's core speed?
The STM8AL3146TAY runs at 16 MHz.
