NJU6655
Preliminary
64-common X 160-segment + 1-icon common
Bitmap LCD Driver
!
GENERAL DESCRIPTION
The
NJU6655
is a bitmap LCD driver to display graphics or
characters.
It contains 10,400 bits display data RAM, microprocessor
interface circuits, instruction decoder, 64-common and
160-segment + 1-icon-common drivers.
The bit image display data is transferred to the display data
RAM by serial or 8-bit parallel interface.
65 x 160 dots graphics or 10-character 4-line by 16 x 16 dots
character with icon are displayed by
NJU6655
itself.
The wide operating voltage from 2.4 to 5.5V and low operating
current are suitable for battery-powered applications.
The build-in Electrical Variable Resistance is very precision,
furthermore the rectangle outlook is very applicable to COG or
Slim TCP.
