Notes
1.
The minimum value for V
LCDIN
is limited by the supply voltages V
DD1
and V
DD2
:
a) For V
DD1
≤
4.5 V and V
DD2
≤
4.5 V: V
LCDIN
> 4.5 V.
b) For V
DD1
> 4.5 V or V
DD2
> 4.5 V: V
LCDIN
> highest value of V
DD1
or V
DD2
.
All static currents are switched off in Power-down mode; no external clock.

The typical currents are measured on a sample base with the DDRAM and grey-scale registers loaded with data
which would produce the display shown in Fig.23 if an LCD was connected. Extensive use of grey-scales will
increase current consumption compared to black and white mode. If specified, the maximum current is tested with a
regular pattern which is equivalent in current to the display shown in Fig.23.
