General Description
The NJU6450A 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 NJU6450A can combine with the NJU6450A or NJU6451A to expand the display capacity to 32×122 dots or 16×141 dots of graphics or character display by using the extension function of NJU6350A. Furthermore,the incorporated CR oscillator required minimum external component and the wide operating voltage,low current consumption are useful apply to the small sized battery operated items.
