1.1 Scope

This is the Functional Speciﬁcation for the S1D13504 Color Graphics LCD/CRT Controller Chip.

Included in this document are timing diagrams, AC and DC characteristics, register descriptions, and

power management descriptions. This document is intended for two audiences: Video Subsystem

Designers and Software Developers.

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.

The S1D13504 supports LCD interfaces with data widths up to 16 bits. Using Frame Rate Modula-

tion (FRM), it can display 16 shades of gray on monochrome LCD panels, up to 4096 colors on pas-

sive 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. Flexi-

ble operating voltages from 2.7V to 5.5V provide for very low power consumption.
