Manufacturer New Japan Radio

New Japan Radio

Description :

The NJU6452A is a bit map LCD driver to display graphics or characters.

It contains 2, 560 bit display data RAM, microprocessor interface circuits, instruction decoder, and 16-common and 61-segment drivers.

The bit image display data sent from 8- 16-bit MPU are stored in the display data RAM and drivers Dot Matrix LCD Panel by the common and segment drivers.

The 16-common and 61-segment drivers can drive graphics or 12-character 2-line with icon data.

The NJU6452A can combine with the NJU6452A or 6453A to expand the display capacity to 32×122 dots or 16×141 dots of graphics or character display by using the extension function of NJU6452A.

Furthermore, low current consumption due to the external clock input and wide operating voltage are useful apply to the small sized battery operated items.
