A microcontroller has all of the system parts on one piece of silicon. First introduced in 1979-85 (e.g. »Intel 80C51).
Such a microcontroller has an internal D8/A16 architecture and is used in things like a door lock, mouse or smartcard.
Many smartcards today contain a microcontroller that runs a cut-down, integer only, Java VM.
