The NJU6673 is a 25-common x 100-segment bit map LCD driver to display graphics or characters.
NJU6673 contains 2,500 bits display data RAM, microprocessor interface circuits, instruction decoder, and common and segment drivers.
An image data from MPU NJU6673 through the serial or 8-bit parallel interface are stored into the 2,500 bits internal displayed on the LCD panel through the commons and segments drivers.
The NJU6673 displays 25 x 100 dots graphics or 7-character 2-line by 12 x 13 dots character.
The NJU6673 contains a built-in OSC circuit for reducing external components. And it features an electrical variable resistor. As result, it reduces the operating current.
The operating voltage from 2.4V to 5.5V and low operating current are suitable for small size battery operation items.
