LCD DISPLAY
A custom-made segmented LCD glass, manufactured by the Varitronix Corporation, is
provided as shown in Figure A-2. This LCD has 4 commons and 32 segments.
Table A-2 provides a few of the specifics for the display. Refer to the Varitronix
specification sheet (VL_5573_V00) for additional details.

Since the glass used on the PICDEM LCD 2 operates at 3V, there is a voltage protec-
tion circuit on the LCDBIAS3 pin, which is enabled in the default configuration. When
enabled, even if the V DD is greater than 3V, it regulates the LCDBIAS3 voltage such
that it always maintains the value to 3V. This is not necessary for operation of the LCD
module, but it is a protection circuit to prevent accidentally applying voltages higher
than 3V to the LCD glass present on the board.
