■ABSOLUTE MAXIMUM RATINGS
* :Don’t exceed 4.0V
WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
■RECOMMENDED OPERATING CONDITIONS
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device's electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor de vices within their recommended oper ating condition r anges . Oper ation
outside these ranges may adversely affect reliability and could result in device failure.
No warr anty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.

■USAGE PRECAUTIONS
• Be sure to ground the pins of AVDD, DVDD, VRT and VRB via high-frequency capacitor. Place the high-frequency
capacitor as close as possible to the pin.
• You can minimize the power supply current dissipation due to the internal logic indetermination by making the
clock to 4CLK or higher.
