Hitachi HD66765
The HD66765’s bit-operation functions, 16rbit high-speed bus interface, and high-speed RAM-write functions enable efficient data transfer and ahigh-speed rewriting of data to the graphics RAM. The HD66765 has a low-voltage operation (1.8 V min.) and an internal RAM to display a maximum of 132RGB-by-176-dot color, and the HD66764 has a step-up circuit to generate the LCD- edrive voltage, a bleeder resistor for the drive interface with the LCD, and voltage-followers.| Part No. | HD66765 |
