The PIC16C925/926 Rev. A2 parts you have received
conform functionally to the Device Data Sheet
(DS39544A), except for the anomalies described
below.
All the problems listed here will be addressed in future
revisions of the PIC16C925/926 Rev. A2 silicon.

The current source associated with the LCD mod-
ule charge pump has a nominal output of 10 A.
However, current regulation within individual
devices may vary from approximately 8.5 to 12 A.
Since this current sets up the V
variation in this current can create noticeable LCD
contrast variations when using the LCD charge
pump.
Work around
One method to compensate for the varying current
regulation is to include a trim potentiometer in
series between the V
method is currently noted in Figure 11-9 (page 95)
of the Device Data Sheet.
To reduce the variation in the V
without using a trim potentiometer or trim resistors
(which must be manually adjusted), it is possible to
use a bandgap voltage reference circuit such as
the 1.22V ZXRE1004 reference from Zetex, as
shown in Figure 1. Resistor Rx placed in series
with the bandgap reference and the V
can be used to set a voltage higher than the band-
gap reference voltage, if necessary. The voltage is
determined by the formula
As can be seen from this equation, a smaller
series resistor results in smaller variations in
