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
Pin names in parentheses (...) indicate alternate functions.
