PREFACE
s Objective and Intended Readership of This Manual
The MB89980 series has been developed as a general-purpose version of the F2MC*-8L family
consisting of proprietary 8-bit, single-chip microcontrollers. The MB89980 series is applicable to
a wide range of applications from welfare products to industrial equipment, including portable
devices.
This manual describes the functions and operation of the MB89980 series and is aimed at
engineers using the MB89980 series of microcontrollers to develop actual products. See the
F2MC-8L MB89600 Series Programming Manual for details on the MB89980 instruction set.
*: F2MC stands for FUJITSU Flexible Microcontroller.
