Description
61
VCI
Voltage converter input terminal
63
VOUT
Voltage converter output terminal
84
V0
LCD driving voltage terminals
83
V1
• When the internal power circuits are used, the LCD driving voltages (V0 to V4) are
82
V2
enabled by the “Power control set” instruction and an LCD bias ratio is selected by
81
V3
the “LCD bias set” instruction.
80
V4
• When the internal power circuits are not used, the external voltages (V0 to V4) are
required on these terminals. The external voltages should be maintained in the
relationship: VSS<V4<V3<V2<V1<V0.
