■ OUTLINE

The MB89680 series is a line of single-chip microcontrollers. In addition to a compact instruction set, the microcontrollers contain a variety of peripheral functions such as dual-clock control system, four operating speed control stages, timers, PWM timer, a serial interface, a UART, an A/D converter, and an external interrupt.
