ok fediverse i need help with a question that has been surprisingly resistant to web searches: when did it begin to become common (or at least not surprising) for microcontrollers and processors to run at 3.3v, rather than 5v (or more)—especially in embedded and portable contexts? who was the first vendor in this area who was like "sure, let's take a chance on 3.3v"? (did it happen in industrial applications before it happened in consumer electronics?)
