1 INTRODUCTION
1.1 Scope
This is the Functional Specification for the S1D13503 Dot Matrix Graphic Color LCD Controller. 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
This device is designed for products where low cost, low power consumption, and low component count are the major
design considerations. This chip operates from 2.7 Volts to 5.5 Volts and up to 25MHz to suit different power consumption,
speed and cost requirements. The S1D13503 offers a flexible microprocessor interface, and is pin compatible with the
S1D13502 within the same package types (e.g. the 13503D0A is pin compatible with the 13502; the 13503 is pin
compatible with the 13502).
The S1D13503 is capable of displaying a maximum of 16 levels of gray shade or 256 simultaneous colors. In gray shade
modes, a 16x4 Look-Up Table is provided to allow remapping of the 16 possible gray shades displayed on the LCD panel.
In color modes, three 16x4 Look-Up Tables are provided to allow remapping of the 4096 possible colors displayed on the
LCD panel. The S1D13503S1D13503 can interface to an MC68000 family microprocessor or an 8/16-bit MPU/Bus with
minimum external “glue” logic. This device can directly control up to 128K bytes of static RAM with a 16-bit data path,
or up to 64K bytes with an 8-bit data path.
