f. External expansion of segment
With this LSI, there are two ways of providing LCD power: by using the on-chip power
supply circuit, or by using an external circuit.
When the on-chip power supply circuit is used for the LCD drive power supply, the V
V
When an external power supply circuit is used for the LCD drive power supply, connect the
external power supply to the V
figure 13.4 (b).
Use of a low-power-consumption LCD drive system enables the power consumption
required for LCD drive to be optimized. For details, see section 13.3.4, Low-Power-
Consumption LCD Drive System.
Segment can be expanded by externally connecting the HD66100. For details, see section
13.3.7, Connection to HD66100.
