1/3 , 1/4 Duty LCD Driver
GENERAL DESCRIPTION
The
NJU6535
is a 1/3 or 1/4 duty LCD driver for
segment type LCD panel with key scan function
transmitting the 30 keys maximum scanned data (6 x 5 =
30) to CPU.
The
NJU6535
chooses numbers of common, key scan,
and general purpose ports by instructions. Therefore, It
drives 126 segments at 1/3 duty in use of 3 commons and
42 segments or 164 segments at 1/4 duty in use of 4 and
41. Also it provides 4 general purpose output ports
maximum to drive LEDs or others directly.
Furthermore, the NJU6535 can select a LCD driving
voltage out of 8 steps voltage by the instruction to adjust
