S1D13504 COLOR GRAPHICS LCD/CRT CONTROLLER
February 2001
■
DESCRIPTION
The S1D13504 is a low cost, low power, color/monochrome LCD/CRT controller interfacing to a wide range of CPUs
and LCDs. The S1D13504 architecture is designed to meet the requirements of embedded markets such as Office
Automation equipment, Mobile Communications devices and Hand-Held PCs where Windows CE may serve as a
primary operating system.
The S1D13504 supports LCD interfaces with data widths up to 16-bits. Using Frame Rate Modulation (FRM), it can
display 16 shades of gray on monochrome LCD panels, up to 4096 colors on passive color LCD, and 64K colors on
active matrix TFT LCD panels. CRT support is handled through the use of an external RAMDAC interface allowing
simultaneous display of both the CRT and LCD panel. A 16-bit memory interface supports up to 2M bytes of FPM-
DRAM or EDO-DRAM. Supports flexible operating voltages from 2.7V to 5.5V.
