■ DESCRIPTION
The MB89120 series is a line of single-chip microcontrollers containing a compact instruction set and a great variety of peripheral functions such as a timer, serial interface, and external interrupt. The MB89120A series is an extended variant of the MB89120, with a remote control transmission function and wake-up interrupt channels.
