New Japan Radio NJU6657
NJU6657
Preliminary
88-common x 272-segment
Bitmap LCD Driver
GENERAL DESCRIPTION
The NJU6657 is a bitmap LCD driver to display graphics or
characters.
It contains 23,936 bits display data RAM, microprocessor
interface circuits, instruction decoder, 88-common and
272-segment drivers.
The bit image display data is transferred to the display data
RAM by serial or 8-bit parallel interface.
88 x 272 dots graphics or 17-character 5-line by 16 x 16 dots
character with icon are displayed by NJU6657 itself.
The NJU6657 contains a built-in OSC circuit for reducing
external components.
The wide operating voltage from 2.7 to 5.5V and low operating
current are suitable for battery-powered applications.
