1.2 Overview 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.
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 LCDs, 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. Flexible operating voltages from 2.7V to 5.5V provide for very low power consumption.
