Overview

The CL-GD6410 is a high-integration LCD VGA controller designed specifically for notebook computers, focusing on reducing form factor and minimizing power consumption. This single-chip VGA controller delivers outstanding LCD image quality, supports simultaneous CRT and LCD operation (SimulSCAN™), and offers advanced power-saving features.

Key Features:

• Single-chip VGA controller
• IBM VGA hardware-compatible
• Simultaneous CRT and LCD (SimulSCAN™) operation
• Two 256K x 4 DRAM video memory for small form factor
• Integrated RAMDAC and LCD panel interface
• Direct connection to ISA (PC AT) Bus
• Frame-Accelerator for low-active power
• Standby and Suspend Modes to save power
• Expanded operational range: 5V + 10%, low-voltage (4.5V) operation saves power
• 64-shade grayscale on monochrome STN LCD with NTSC sum-to-gray color mapping and multiple sum-to-gray weighting options
• Direct connection to 512-color TFT LCD
• Graphics and text expansion and compression maps
• CRT modes to fixed-resolution LCD
• 800 x 600 x 16 color on analog CRT
• 8- or 16-bit CPU interface
• 160-pin (EIAJ-standard) QFP package with optimized pinout for efficient board layout

The CL-GD6410 offers a complete motherboard VGA controller solution, requiring only four or five ICs and fitting within four square inches. By using Cirrus Logic's Frame-Accelerator technique, this controller provides a high vertical refresh rate for dual-scan LCD panels while operating at half the clock speed of other LCD controller solutions, reducing full-active power consumption and extending battery life. The CL-GD6410 supports Standby and Suspend Modes for further power management and offers excellent display quality on a variety of panels. With SimulSCAN™ operation, the portable computer can become a key part of presentation environments for sales force automation, field service, and educational organizations.
