Description
Q’ty
Board potential
IC board is based on VDD potential. To lock the board potential with VDD.
VDD
Power supply Connected to the logic power supply. This is used in common with
6
the MPU power pin VCC.
VSS
Power supply 0 V power pin that is connected to system GND.
4
V0, V1
Power supply Multi-level power supply for liquid crystal drive.
6
V2, V3
The voltage determined for the liquid crystal cell is applied by
V4, V5
resistance-division or impedance conversion by operational
amplifier. The potential is determined on VDD and the following
relations must be observed.
VDD = V0
≥ V1 ≥ V2 ≥ V3 ≥ V4 ≥ V5
VDD
≥ V5 ≥ VOUT
VDD
≥ VSS ≥ VSS2 ≥ VOUT
When the built-in power supply is ON, the following voltages are
given to V1 to V4 by command selection.
V1 = 1/5 V5
1/4 V5
V2 = 2/5 V5
2/4 V5
V3 = 3/5 V5
2/4 V5
V4 = 4/5 V5
3/4 V5
VS1
O
Supply voltage output pin for oscillating circuit.
1
Don’t connect a load to the outside.
