HD66766
(132 x 176-dot Graphics LCD Controller/Driver for 65K Colors)
Rev.1.0
November, 2001
Description
The HD66766, color-graphics LCD controller and driver LSI, displays 132-by-176-dot graphics for 65K
STN colors. A 16-bit high-speed bus interface and high-speed RAM write function enable efficient data
transfer and high-speed rewriting of data to the graphics RAM.
The HD66766 has various functions for reducing the power consumption of a LCD system, such as low-
voltage operation of 2.2 V/min., a step-up circuit to generate a maximum of 12-times the LCD drive
voltage from the supplied voltage, and voltage-followers to decrease the direct current flow in the LCD
drive bleeder-resistors. Combining these hardware functions with software functions, such as a partial
display with low-duty drive and standby and sleep modes, allows precise power control. The HD66766
is suitable for any mid-sized or small portable battery-driven product requiring long-term driving
capabilities, such as digital cellular phones supporting a WWW browser, bi-directional pagers, and small
PDAs.
Features
• 132RGB x 176-dot graphics display LCD controller/driver for 65K STN colors
• low voltage drive and flickerless PWM grayscale drive
• 16-/8-bit high-speed bus interface and Clock Synchronized Serial 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.

• Various color-display control functions
- 65K out of 140K possible colors can be displayed at the same time (grayscale palette
incorporated)
- Vertical scroll display function in raster-row units
• Low-power operation supports:
- Vcc = 2.2 to 3.6 V (low-voltage)
- Common driving voltage = 8 to 44 V
- Segment driving voltage = 2 to 4 V
- VOUT power voltage = 4.5V to 5.5 V
- Maximum 12-times step-up circuit for liquid crystal drives voltage and voltage inverting circuit
- 128-step contrast adjuster and voltage followers to decrease direct current flow in the LCD drive
bleeder-resistors
- Power-save functions such as the standby mode and sleep mode
- Partial LCD drive of two screens in any position
- Programmable drive duty ratios (1/8–1/176) and bias values (1/2–1/13) displayed on LCD
• Internal RAM capacity: 46,464 bytes
• 396-segment × 176-common liquid crystal display driver
• n-raster-row AC liquid-crystal drive (C-pattern waveform drive)
• Internal oscillation and hardware reset
• Shift change of segment and common drivers
• COM positioned on both sides in one chip for COG
