PREFACE

■Objectives and Intended Reader

The MB89950/950A series has been developed as a general-purpose version of the F2MC-8L family

consisting of proprietary 8-bit, single-chip microcontrollers. The MB89950/950A series is applicable to a

wide range of applications from consumer products to industrial equipment, including portable devices.

This manual describes the functions and operation of the MB89950/950A series and is aimed at engineers

using the MB89950/950A series of microcontrollers to develop actual products. See the F2MC-8L MB89600

Series Programming Manual for details on the MB89950/950A instruction set.

■Trademarks

F2MC is the abbreviation of FUJITSU Flexible Microcontroller.

Other system and product names in this manual are trademarks of respective companies or organizations.

The symbols TM and ® are sometimes omitted in this manual.

• The products described in this document are designed, developed and manufactured as contemplated for general

use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but

are not designed, developed and manufactured as contemplated (1) for use accompanying fatal risks or dangers

that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to

death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility,

aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control

in weapon system), or (2) for use requiring extremely high reliability (i.e., submersible repeater and artificial

satellite).

connection with above-mentioned uses of the products.

• Any semiconductor devices have an inherent chance of failure. You must protect against injury, damage or loss

from such failures by incorporating safety design measures into your facility and equipment such as redundancy,

fire protection, and prevention of over-current levels and other abnormal operating conditions.

• If any products described in this document represent goods or technologies subject to certain restrictions on export

under the Foreign Exchange and Foreign Trade Law of Japan, the prior authorization by Japanese government will

be required for export of those products from Japan.
