Recommended Conditions
(VSS
= AVSS = DVSS = 0 V)
* :
Use a ceramic capacitor, or a capacitor of similar frequency characteristics. On the VCC pin (pin 15) , use a bypass
capacitor that has a larger capacity than that of CS. On the other VCC pin (pin 105) , use a bypass capacitor of
about 0.1
F.
Refer to the following figure for connection of smoothing capacitor CS.
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 devices within their recommended operating condition ranges. 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 representatives beforehand.
