64-Common X 160-Segment + 1-icon Bitmap LCD Driver

Manufacturer's part number :


Manufacturer New Japan Radio

New Japan Radio

Description :

The NJU6655B 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 NJU6655B 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.
