Shared with the MPU power supply terminal V
This is a 0V terminal connected to the system GND.
This is the reference power supply for the step-up voltage circuit for the
liquid crystal drive.
This is the externally-input VREG power supply for the LCD power supply
voltage regulator.
These are only enabled for the models with the VREG external input option.
This is a multi-level power supply for the liquid crystal drive. The voltage
applied is determined by the liquid crystal cell, and is changed through the
use of a resistive voltage divided or through changing the impedance using
an op. amp. Voltage levels are determined based on VDD, and must
maintain the relative magnitudes shown below.
Master operation: When the power supply turns ON, the internal power
supply circuits produce the V1 to V4 voltages shown below. The voltage
settings are selected using the LCD bias set command.
DC/DC voltage converter. Connect a capacitor between this terminal and
the CAP1- terminal.
DC/DC voltage converter. Connect a capacitor between this terminal and
the CAP1+ terminal.
DC/DC voltage converter. Connect a capacitor between this terminal and
the CAP2- terminal.
DC/DC voltage converter. Connect a capacitor between this terminal and
the CAP2+ terminal.
DC/DC voltage converter. Connect a capacitor between this terminal and
the CAP1+ terminal.
DC/DC voltage converter. Connect a capacitor between this terminal and
V
Output voltage regulator terminal. Provides the voltage between V
V5 through a resistive voltage divider.
These are only enabled when the V
not used (IRS = “L”).
These cannot be used when the V
used (IRS = “H”).
