The SED1355 is a color/monochrome LCD/CRT graphics controller interfacing to a wide range of
CPUs and display devices. The SED1355 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 SED1355 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 supported, while the Hardware Cursor, Ink Layer, and the Memory Enhancement
Registers offer substantial performance benefits. These features, combined with the SED1355’s
Operating System independence, make it an ideal display solution for a wide variety of applications.
