HD66766R Datasheet, PDF (2/97 Pages) Hitachi Semiconductor – 132 x 176-dot Graphics LCD Controller/Driver for 65K Colors

HD66766R
Rev. 1.0-1 / September 2002
• 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
- Partial LCD drive of two screens in any position
• 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 = 4.0V to 5.75 V
- Power-save functions such as the standby mode and sleep mode
- Internal power supply circuit
- Programmable drive duty ratios (1/8–1/176) and bias values (1/2–1/13) displayed on LCD
- 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
• 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
