1 INTRODUCTION
1.1 Scope
This is the Functional Specification for the SED1352 Dot Matrix Graphic Display LCD 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; Graphics 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 SED1352 offers a flexible microprocessor interface.
The SED1352 is capable of displaying a maximum of 16 levels of gray. A 16x4 Look-Up Table is provided to allow
remapping of the 16 possible gray shades displayed on the LCD panel. The SED1352 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.
