NJU6678 - 104-common x 132-segment BIT MAP LCD DRIVER

General Description

The NJU6677 is a bit map LCD driver to display graphics or characters.

It contains 15,840 bits display data RAM, microprocessor interface circuits, instruction decoder, 132-segment and 88-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 2.4V to 3.6V and low operating current are useful for small size battery operating items.

NJU6677 PRELIMINARY 88-common x 132-segment BIT MAP LCD DRIVER GENERAL DESCRIPTION The NJU6677 is a bit map LCD driver to display graphics or characters. It contains 15,840 bits display data RAM, microprocessor interface circuits, instruction decoder, 132-segment and 88-common drivers. The bit image display data is transferred to the display data RAM by serial or 8-bit parallel interface. The NJU6677 displays 88 x 132 dots graphics or 8-character 5-line by 16 x 16 dots character. It oscillates by built-in OSC circuit without any external components. Furthermore, the NJU6677 features Partial Display Function which creates up to 2 blocks of active display area and optimizes duty cycle ratio.
