NJU6635
PRELIMINARY
16-CHARACTER 2-LINE DOT MATRIX LCD
CONTROLLER DRIVER
s GENERAL DESCRIPTION
s PACKAGE OUTLINE
The NJU6635 is a 1Chip Dot Matrix LCD controller
driver for up to 16-character 2-line display with double
height function.
It contains microprocessor Interface circuits,
Instruction decoder controller, character generator
ROM/RAM and common and segment drivers.
The bleeder resistance generates for LCD Bias
voltage Internally.
The CR oscillator Incorporates C and R, therefore no
external components for oscillation are required.
The microprocessor Interface circuits which operate
2MHz frequency, can be connected directly to 4/8bit
microprocessor.
The character generator consists of 9,600 bits ROM
and 32 x 5 bits RAM. The standard version ROM is
coded with 240 characters including capital and small
letter fonts.
The 16-common and 80-segment drive up to
16-character 2-line LCD panel which divided two
common electrode blocks.
The rectangle outlook is very applicable to COG.
