www.DataSheet4U.com NJU6678V 104-common x 132-segment BIT MAP LCD DRIVER GENERAL DESCRIPTION The NJU6678V is a 104-common x 132-segment bit map LCD driver to display graphics or characters. It contains 21,120 bits display data RAM, microprocessor interface circuits, instruction decoder, and common and segment drivers. An image data from CPU through the serial or 8-bit parallel interface are stored into the 21,120 bits internal display data RAM and are displayed on the LCD panel through the commons and segments drivers. The NJU6678V displays 104 x 132 dots graphics or 8-character 6-line by 16 x 16 dots character. The NJU6678V contains a built-in OSC circuit for reducing external components. And it features Partial Display Function containing selectable active display block(s) (two blocks max.) and optimizing the duty cycle ratio. This function dramatically reduces the operating current, setting the optimum boosted voltage combined with a programmable voltage booster circuit and an electrical variable resister. As result, it reduces the operating current. The operating voltage from 2.5V to 3.3V and low operating current are suitable for small size battery operation items.
