■PIN ASSIGNMENT
■PIN DESCRIPTION
Values within ( ) are typical values.
■NOTES ON USE
• Be sure to bypass the AVDD, DVDD, VRT and VRB pins to the ground using a high-frequency capacitor.
The high-frequency capacitor should be connected as near the pin as possible.
• Provide four clocks or more immediately after the power up to prevent current dissipation due to the
indeterminate internal logic.

■ABSOLUTE MAXIMUM RATINGS (See WARNING)
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: Recommended operating conditions are normal operating ranges for the semiconductor device. All
the device’s electrical characteristics are warranted when operated within these ranges.
Always use semiconductor devices within the recommended operating conditions. Operation outside
these ranges may adversely affect reliability and could result in device failure.
No warranty 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 representative beforehand.
