160-common x 132-segment
DOT MATRIX LCD DRIVER FOR 4 GRAY SCALE
sGENERAL DESCRIPTION
The NJU6682 is a bit map LCD driver to display graphics or characters.
It contains 84,480 bits display data RAM, microprocessor interface circuits,
instruction decoder, and 160-common and 132-segment drivers.
The bit image data is transferred to the internal display data RAM by
serial interface or 8-bit/16-bit parallel interface.
The NJU6682 features 4-gray scale function which creates 4 types gray
scale (for example : white/light gray/dark gray/black) or black & white with
displays 160 x 132 dots graphics or 8-caracter 10line by 16 x 16 dots
characters.
It oscillates by built-in OSC circuit without any external components.
Furthermore, the NJU6682 features Partial Display Function which
creates up to 2 blocks of active display area and optimizes duty cycle ratio.
This function sets optimum boosted voltage by the combination with both
of programmable voltage booster circuit and electrical variable resister. As
result, it reduces the operating current.
The operating voltage from 2.4V to 3.3V and low operating current are
useful for small size battery operating items.
