Preliminary
5. This excludes the current flowing through output drive MOSs. This excludes the current flowing
through the input/output units. The input level must be fixed high or low because through current
increases if the CMOS input is left floating. Even if the CS pin is low or high when an access with the
interface pin is not performed, current consumption does not change.
6. The following figure shows the relationship between the operation frequency and current consumption.

7. This is a voltage difference for the neighboring outputs under the same display condition. The output
voltage deviation is a reference value.
8.
T.B.D. ^{The fluctuation of average output voltage indicates the difference of average output voltage between}
chips. The average output voltage is an average voltage within a chip under the same display
condition.
9. Applies to the case when clocks are supplied internally (figure).
