NJU6679 - 128-common x 132-segment BIT MAP LCD DRIVER

General Description

The NJU6678 is a bit map LCD driver to display graphics or characters.

It contains 21,120 bits display data RAM, microprocessor interface circuits, instruction decoder, 132-segment and 104-common drivers.

Key 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 5-time voltage booster circuit and 201step electrical variable resistor. As result, it reduces the operating current. The operating voltage from 2.5V to 3.3V and low operating current are useful for small size battery operating items.

NJU6678 PRELIMINARY 104-common x 132-segment BIT MAP LCD DRIVER GENERAL DESCRIPTION The NJU6678 is a bit map LCD driver to display graphics or characters. It contains 21,120 bits display data RAM, microprocessor interface circuits, instruction decoder, 132-segment and 104-common drivers. The bit image display data is transferred to the display data RAM by serial or 8-bit parallel interface. The NJU6678 displays 104 x 132 dots graphics or 8-character 6-line by 16 x 16 dots character. It oscillates by built-in OSC circuit without any external components. Furthermore, the NJU6678 features Partial Display Function which creates up to 2 blocks of active display area and optimizes duty cycle ratio.
