Color Graphics LCD/CRT Controller
I
DESCRIPTION
The SED1354 is a low cost, low power color/monochrome LCD/CRT controller interfacing to a wide range of CPUs and
LCDs. The SED1354 architecture is designed to meet the requirements of embedded markets such as Office Automation
equipment, Mobile Communications devices and Hand-Held PCs where Windows CE may serve as a primary operating
system.
The SED1354 supports LCD interfaces with data widths up to 16 bits. Using Frame Rate Modulation (FRM), it can display
16 shades of gray on monochrome LCD panels, up to 4096 colors on passive color LCDs, and 64K colors on active matrix
TFT LCD panels. CRT support is handled through the use of an external RAMDAC interface allowing simultaneous display
of both the CRT and LCD panel. A 16-bit memory interface supports up to 2M bytes of FPM-DRAM or EDO-DRAM.
Flexible operating voltages from 2.7V to 5.5V provide for very low power consumption.
