REF
This pin is an input pin to enable the internal reference voltage used for the internal regulator.
When it is high, an internal reference voltage source will be used. When it is low, an external
reference voltage source must be provided in V
Power supply pin.
Ground.
Reference voltage input for internal DC-DC converter. The voltage of generated V
the multiple factor (3X, 4X, 5X or 6X) times V
Note: voltage at this input pin must be larger than or equal to V
This is the most positive voltage supply pin of the chip. It can be supplied externally or
generated by the internal DC-DC converter.
When using internal DC-DC converter as generator, voltage at this pin is for internal reference
only. It CANNOT be used for driving external circuitry.
When internal DC-DC voltage converter is used, external capacitor(s) is/are connected among
these pins.
This pin is the most positive LCD driving voltage. It can be supplied externally or generated by
the internal regulator.
This pin is an input of the internal voltage regulator. When the internal resistors network for the
voltage regulator is disabled (INTRS is pulled low), external resistors should be connected
between V
This pin is an input to provide an external voltage reference for the internal voltage regulator
when REF pin is pulled L. When internal reference is selected (REF is pulled high), the V
should be left open (No connection).
