1.2 Overview Description
The S1D13705 is a color / monochrome LCD graphics controller with an embedded 80K
byte SRAM display buffer. The high integration of the S1D13705 provides a low cost, low
power, single chip solution to meet the requirements of embedded markets such as Office
Automation equipment, Mobile Communications devices, and Hand-Held PCs where
board size and battery life are major concerns.
Products requiring a “Portrait” display can take advantage of the SwivelView™ Mode
feature of the S1D13705. Virtual and Split Screen are just some of the display modes
supported. The above features, combined with the Operating System independence of the
S1D13705, make it the ideal solution for a wide variety of applications.
