Single DRAM LCD/VGA
Controllers for Monochrome/
Color Notebook Computers
OVERVIEW
The CL-GD62XX (CL-GD6205/’6215/’6225/’6235) fam-
ily 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 mini-
mizes the form-factor requirement for color and mono-
chrome graphics subsystems. All necessary panel-
power 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 con-
figurations are supported.
With integrated Frame-Accelerator technology, the
CL-GD62XX controllers feature low-power LCD opera-
tion, yet support high LCD panel vertical-refresh rates.
No additional DRAMs are required for frame
