Epson Research and Development Page 7 Vancouver Design Center 1 Introduction 1.1 Scope 1.2 Overview Description This is the Hardware Functional Specification for the S1D13700F00 Embedded Memory Graphics 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. This document is updated as appropriate. Please check the Epson Research and Development Website at www.erd.epson.com for the latest revision of this document before beginning any development. We appreciate your comments on our documentation. Please contact us via email at documentation@erd.epson.com. The S1D13700F00 Embedded Memory Graphics LCD Controller can display both text and graphics on an LCD panel. The S1D13700F00 allows layered text and graphics, scrolling of the display in any direction, and partitioning of the display into multiple screens. It includes 32K bytes of embedded SRAM display memory which is used to store text, character codes, and bitmapped graphics. The S1D13700F00 handles display controller functions including: transferring data from the controlling microprocessor to the buffer memory, reading memory data, converting data to display pixels, and generating timing signals for the LCD panel. The S1D13700F00 is designed with an internal character generator which supports 160, 5x7 pixel characters in internal mask ROM (CGROM) and 64, 8x8 pixel characters in character generator RAM (CGRAM). When the CGROM is not used, up to 256, 8x16 pixel characters are supported in CGRAM. Hardware Functional Specification S1D13700F00 Issue Date: 2004/10/18 X42A-A-001-04 Revision 4.0
