HD66765
396-channel Segment Driver with Internal RAM for 4096-color
Displays
Target Specification
Rev.0.1
January, 2001
Description
The HD66765, 396-channel segment driver LSI, displays 132RGB-by-176-dot graphics on STN
displays in 4096 colors. It is for driving STN color LCD displays to a maximum of 132RGB by 176
dots, in combination with the HD66764 common driver. The HD66765'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 HD66765 and HD66764 have various functions for reducing the power consumption of an LCD
system. 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-
drive voltage, a bleeder resistor for the drive interface with the LCD, and voltage-followers. Since the
HD66765 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.
Features
132RGB x 176-dot graphics display LCD controller/driver for 4,096 STN colors (when HD66764
is used)
Low-voltage drive and flickerless PWM grayscale drive
16-/8-bit high-speed bus interface and serial peripheral interface (SPI)
High-speed burst-RAM write function
Writing to a window-RAM address area by using a window-address function
Bit-operation functions for graphics processing:
Write-data mask function in bit units
Logical operation in pixel unit and conditional write function
