■DESCRIPTION

The MB89180 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, a remote control

transmission output, external interrupts, an LCD controller/driver, and a watch prescaler.
