NJU6631A
PRELIMINARY
16-CHARACTER 1-LINE DOT MATRIX
LCD CONTROLLER DRIVER
s
GENERAL DESCRIPTION
The
NJU6631A
is a 1 Chip Dot Matrix LCD controller
driver for up to 16-character 1-line or 8-character 2-line
display.
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 4bit/8bit
microprocessor.
The character generator consists of 9,600 bits ROM
and 32 x 5 bits RAM. The standard version ROM is
coded with 192 characters including capital and small
letter fonts.
The 16-common and 40-segment drives up to 16-
character 1-line LCD panels which divided two common
electrode blocks.
The rectangle outlook is very applicable to COG or
Slim TCP.
