CL-GD6245-65VC-B

The CL-GD6245-65VC-B belongs to CL-GD6245 family, which  is an advanced, single-chip, that panel VGA controller designed for notebook and subnotebook systems with stringent form-factor and power-consumption requirements. The GL-GD6245 combines the RAMDAG, frequency synthesizer, monochromefcolor STNITFF panel interface, panel power-sequencing logic, host bus interface, and all other functional logic necessary to operate a VGA-compatible video subsystem. This video subsystem is completed with the addition of a single 256l-( x 1 6 DRAM. To further minimize board space, the CL-GD5245 controller is packaged in a 176-pin VQFP package, which also features a minimized height for use on boards with two-sided component assembly. The panel and video-memory interlaces are optimized to allow SimulSCAN operation in a single-DRAM confi uration with dualescan panels. This function is implemented without compromising any features of the controller {for specifics of operation, refer to the GL-GD6245 Data Book).

The features of CL-GD6245 can be summarized as (1)176-pin (EIAJ standard) VQFP package: small form factor; thin (1.4 mm) package ; (2)Direct connection to host bus: 32-bit'486 local bus; VESAG VL-Busm; 16-bit' *386 local bus; ISA bus (PC AT); (3)intograted dual-scan color STN LCD support: requires only 1/2 Mbyte of video memory; simul SCANTM available with no feature compromise; integrated frame~aocelerator for less power consumption ; (4)integrated support for other LCD panels: single-scan color STN; single- and dual-scan monochrome STN; 9-,12-, 15-, and 15-bit color TFT; multi-shade monochrome TFT ; (5)up to 256 colors (at 640 x 480) with color STN and TFT; (6)panels ; (7)up to 64 shades (at 640 x 480) with monochrome STN ; (8)and TFT panels ; (9)simultaneous CRT and LCD operation in all configurations ; (10)CRT resolution up to 1024 x 768 with 15 colors; 800 x ; (11)600 with 256 colors: maximum 85-MHz video clock at 5.QV; maximum 40-MHz video clock at 3.3V; 132-column text rnodcs; (12)supports 3.3V and 5.0V mixed-voltage operation.

The CL-GD6245 LCD VGA controller is supported by a complete documentation package, Cirrus logic BIOS kit, software drivers kit, and evaluation board kit.These kits include all necessary documenlation and schematics to facilitate stem evaluation and design.
