OVERVIEW
The CL-GD62XX (CL-GD6205/’6215/’6225/’6235) family of advanced single-chip flat panel VGA controllers are designed for use in portable systems with stringent power consumption and form-factor requirements. Product family pin compatibility provides easy upgrade capability to color or higher-performance systems. Integration of the frequency synthesizer, RAMDAC, monochrome and color STN/TFT panel interfaces minimizes the form-factor requirement for color and monochrome graphics subsystems. All necessary panelpower sequencing logic has been integrated into the CL-GD62XX family, and a complete graphics subsystem can be built using only two active components (in less than three square inches). The CL-GD62XX family uses a single 256K x 16 DRAM (or four 256K x 4 DRAMs) for video memory. For added flexibility, dual-CAS*-DRAM and dual-WE*-DRAM configurations are supported. With integrated Frame-Accelerator technology, the CL-GD62XX controllers feature low-power LCD operation, yet support high LCD panel vertical-refresh rates. No additional DRAMs are required for frame (cont.)
