GENERAL DESCRIPTION
s
PACKAGE
The NJU6676 is a bit map LCD driver to display
graphics or characters. It contains 8,580 bits display data
RAM, microprocessor interface circuits, instruction
decoder, 132-segment drivers, 64-common drivers and 1-
icon drivers.
The bit image display data is transferred to the display
data RAM by serial or 8-bit parallel interface.
65 x 132 dots graphics or 8-character 4-line by 16 x 16
dots character with icon are displayed by NJU6676 itself.
The wide operating voltage from 2.2 to 5.5V and low
operating current are useful for small size battery
operating items.
The build-in Electrical Variable Resistance is very
precision, furtheremore the rectangle outlook is very
applicable to COG or Slim TCP.
