The bit image display data is transferred to the display data RAM by The bit image display data is transferred to the display data RAM by serial or 8-bit parallel interface. serial or 8-bit parallel interface. The NJU6677 displays 88 x 132 dots graphics or 8-character 5-line by The NJU6677 displays 88 x 132 dots graphics or 8-character 5-line by 16 x 16 dots character. 16 x 16 dots character. It oscillates by built-in OSC circuit without any external components. It oscillates by built-in OSC circuit without any external components. Furthermore, the NJU6677 features Partial Display Function which Furthermore, the NJU6677 features Partial Display Function which creates up to 2 blocks of active display area and optimizes duty cycle creates up to 2 blocks of active display area and optimizes duty cycle ratio. This function sets optimum boosted voltage by the combination ratio. This function sets optimum boosted voltage by the combination with both of programmable 5-time voltage booster circuit and 201- with both of programmable 5-time voltage booster circuit and 201- step electrical variable resistor. As result, it reduces the operating cur- step electrical variable resistor. As result, it reduces the operating cur- rent. rent. The operating voltage from 2.4V to 3.6V and low operating current are The operating voltage from 2.4V to 3.6V and low operating current are useful for small size battery operating items. useful for small size battery operating items.
