Reference voltage input pin (1 V)
Reference voltage output pin. When connected to VRB, the pin generates
0.2 × AVDD (1 V).
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.

representatives before ordering.
The information and circuit diagrams in this document presented
as examples of semiconductor device applications, and are not
intended to be incorporated in devices for actual use. Also,
FUJITSU is unable to assume responsibility for infringement of
any patent rights or other rights of third parties arising from the
use of this information or circuit diagrams.
FUJITSU semiconductor devices are intended for use in
standard applications (computers, office automation and other
office equipment, industrial, communications, and measurement
equipment, personal or household devices, etc.).
CAUTION:
Customers considering the use of our products in special
applications where failure or abnormal operation may directly
affect human lives or cause physical injury or property damage,
or where extremely high levels of reliability are demanded (such
as aerospace systems, atomic energy controls, sea floor
repeaters, vehicle operating controls, medical devices for life
support, etc.) are requested to consult with FUJITSU sales
representatives before such use. The company will not be
responsible for damages arising from such use without prior
approval.
Any semiconductor devices have inherently a certain rate 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 Control Law of Japan, the
prior authorization by Japanese government should be required
for export of those products from Japan.
