■ DESCRIPTION

The MB89910 series has been developed as a general-purpose version of the F2MC*-8L family consisting of proprietary 8-bit, single-chip microcontrollers.

In addition to a compact instruction set, the microcontrollers contain a variety of peripheral functions such as dual-clock control system, five operating speed control stages, timers, a serial interface, an A/D converter, a buzzer output, a low-voltage detection reset, high-voltage driver, a watch prescaler, and external interrupts.

The MB89910 series is applicable to a wide range of applications from consumer products to industrial equipments.
