SED1352 GRAPHICS LCD CONTROLLER

■DESCRIPTION

The SED1352 is a graphics display LCD controller capable of displaying a maximum of 16 levels of gray on single and dual

scan Liquid Crystal Displays. A 16x4 lookup table is provided to allow remapping of the 16 possible gray shades displayed on

the LCD panel. The SED1352 can interface to the MC68000 microprocessor and 8/16 bit MPUs with READY (WAIT#) signal

with minimum external “glue” logic. This chip can directly control up to 128 Kbytes of static SRAM.

Optimized for cost and power savings, the SED1352 can operate from 2.7 volts to 5.5 volts and up to 25MHz.

■FEATURES

•16-bit 16 MHz MC68000 MPU interface

•8/16-bit MPU interface controlled by a READY (or

WAIT#) signal

•option to use built-in index register or direct-mapping to

access one of fifteen internal registers

•2-terminal crystal input for internal or external

crystal oscillator

•8/16-bit SRAM interface configurations

•two software power-save modes

•low power consumption

•display modes:

2 bit/pixel, 4-level gray-scale display

4 bit/pixel, 16-level gray-scale display

•virtual display support

•display memory interface:

one 1 Mbit SRAM(64Kx16)

one or two 32Kbyte SRAM(s)

one or two 8Kbyte SRAM(s)

one 8Kbyte and one 32Kbyte SRAM

•LCD panel configurations:

single-panel, single-drive display

dual-panel, dual-drive display

•maximum number of vertical lines:

1,024 lines (single-panel, single-drive display)

2,048 lines (dual-panel, dual-drive display)

•split screen display support at single-panel mode

•package:

QFP5-100-S2 package (F0B)

or QFP15-100-STD package (F1B)
