SED1353 GRAPHICS LCD CONTROLLER

The SED1353 is a dot matrix graphic LCD controller supporting resolutions up to 1024x1024. It is

capable of displaying a maximum of 256 simultaneous colors out of a possible 4096 or 16 gray shades.

Design flexibility allows the SED1353 to interface to either an MC68000 family microprocessor or an

8/16-bit MPU/bus with minimum external logic. The Static RAM (SRAM) interface used for the display buffer

is optimized for speed and performance, supporting up to 128K bytes.

Two power save modes, combined with operating voltages of 2.7 volts through 5.5 volts, allow for a wide

range of applications while providing minimum power consumption.
