HD66763

384-channel Segment Driver with Internal RAM for 256-color

Displays

Rev.1.0

July, 2001

Description

The HD66763, 384-channel segment driver LSI, displays 128RGB-by-176-dot graphics on STN

displays in 256 colors. It is for driving STN color LCD displays to a maximum of 128RGB by 176

dots, in combination with the HD66764 common driver. The HD66763’s bit-operation functions, 16-

bit high-speed bus interface, and high-speed RAM-write functions enable efficient data transfer and

high-speed rewriting of data to the graphics RAM.

The HD66763 and HD66764 have various functions for reducing the power consumption of an LCD

system. The HD66763 has a low-voltage operation (1.8 V min.) and an internal RAM to display a

maximum of 128RGB-by-176-dot color, and the HD66764 has a step-up circuit to generate the LCD-

drive voltage, a bleeder resistor for the drive interface with the LCD, and voltage-followers. Since the

HD66763 incorporates a circuit that interfaces with the HD66764, it can set instructions for the

HD66764. In addition, precise power control can be achieved by combining these hardware functions

with software functions, such as a partial display that only requires a low drive-voltage duty, and

standby and sleep modes. This LSI is suitable for any medium-sized or small portable battery-driven

product requiring long-term driving capabilities, such as digital cellular phones supporting a WWW

browser, bidirectional pagers, and small PDAs.
