DESCRIPTION
The S1D13704 is a color/monochrome LCD graphics controller with an embedded 40K Byte SRAM display buffer.
The high integration of the S1D13704 provides a low cost, low power, single chip solution to meet the require-
ments of embedded markets such as Office Automation equipment, Mobile Communications devices, and Palm-
size PCs where board size and battery life are major concerns.
Products requiring a “Portrait” display can take advantage of the Hardware Portrait Mode feature of the S1D13704.
Virtual and Split Screen are just some of the display modes supported. The above features, combined with the
Operating System independence of the S1D13704, make it the ideal solution for a wide variety of applications.
