Major Chips Description
2-41
The C&T65550 offers a variety of programmable features to optimize display quality. Vertical
centering and stretching are provided for handling modes with less than 480 lines on 480-line
panels. Horizontal and vertical stretching capabilities are also available for both text and graphics
modes for optimal display of VGA text and graphics modes on 800x600 and 1024x768 panels.
Three selectable color-to-gray scale reduction techniques and SMARTMAP™ are available for
improving the ability to view color applications on monochrome panels. CHIPS' polynomial FRC
algorithm reduces panel flicker on a wider range of panel types with a single setting for a particular
panel type.
LOW POWER CONSUMPTION
The C&T65550 employs a variety of advanced power management features to reduce power
consumption of the display sub-system and extend battery life. Although optimized for 3.3V
operation, The C&T65550 controller's internal logic. memory interface, bus interface, and panel
interfaces can he independently configured to operate at either 3.3V or 5V.
SOFTWARE COMPATIBILITY/FLEXIBILITY
The C&T65550 are fully compatible with VGA at the register, and BIOS levels. CHIPS and third-
party vendors supply fully VGA-compatible BIOS, end-user utilities and drivers for common
application programs
