Notes:
1. The above ratings represent the maximum values that may be applied without damaging the chip, not the limits for guaranteed
operation.
2. If the chip is to be used in the presence of strong electric fields—under a CRT tube, for example—apply shielding to the package
surface to ensure proper operation.
3. The power dissipation is for an ambient temperature (Ta) of 70˚C.
4. The voltages applied to the pins CCK/SCL, CTLI/SDA, CWO/IFMOD, PO0/MTO, PO1–PO5, and PO6/LIBP must be within
the range between –0.3V and 5.5V when the power is off.

For the logic portions of the microcomputer interface, DV_DD min = 4.0V.
AV_DD covers both AV_DDL and AV_DDR .
AV_SS covers both AV_SSL and AV_SSR .
Analog characteristics are only guaranteed for DV_DD = AV_DD = 5.0V.
2. Always use low-impedance external connections for V_DD and V_SS .
Always connect the two through a bypass capacitor of at least 0.01 µF to ensure proper operation.
3. Keep the NRES pin (pin No. 22) at "L" level to prevent operation error of the CTLI/SDA pin in the I²C interface at voltages
lower than the guaranteed operating power supply voltage.
