Number of pins I/O Name Description
2 Supply V
DD 5V supply. Common to MPU power supply pin VCC.
2 Supply V
SS Ground
11 Supply V
1 to V5 LCD driver supply voltages. The voltage determined by the LCD cell
is impedance-converted by a resistive divider or an operational
amplifier for application. Voltages should be determined on a V
DD-
basis so as to satisfy the following relationship.
The voltages must satisfy the following relationship.
V
DD ≥ V0 ≥ V1 ≥ V2 ≥ V3 ≥ V4 ≥ V5.
When master mode selects, these voltages are generated on-chip.
