I recall Hitachi or a similar Japanese company advertising a small
cheap microcontroller for use in microwave ovens, even including
example source code for a typical microwave. That's probably why all
microwaves have the exact same interface.
As someone else said, high-volume stuff like this usually doesn't
have the processor manufacturer's markings, but rather the customer's
part number which is only meaningful to their purchasing and
Intel's 8048/8051's have been used extensively for computer
keyboard encoders, used in both the IBM/Wintel compatibles and the
original Macintosh (horrors! An Intel chip in a Mac!) keyboards.
