S1D13505 EMBEDDED RAMDAC LCD/CRT CONTROLLER October 2001

■DESCRIPTION
The S1D13505 is a color/monochrome LCD/CRT graphics controller interfacing to a wide range of CPUs and display
devices. The S1D13505 architecture is designed to meet the low cost, low power requirements of the embedded
markets, such as Mobile Communications, Hand-Held PCs, and Office Automation.
The S1D13505 supports multiple CPUs, all LCD panel types, CRT, and additionally provides a number of
differentiating features. Products requiring a “Portrait” mode display can take advantage of the SwivelView feature.
Simultaneous, Virtual and Split Screen Display are just some of the display modes suppor ted, while the Hardware
Cursor, Ink Layer, and the Memory Enhancement Registers offer substantial performance benefits. These features,
combined with the S1D13505’s Operating System independence, make it an ideal display solution for a wide variety
of applications.
