SED1353

GRAPHICS SED1353 October 1998 SED1353 GRAPHICS LCD CONTROLLER s DESCRIPTION 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. s FEATURES pin compatible with the SED1352 16-bit 16 MHz MC68xxx 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 sixteen internal registers 2-terminal crystal or external oscillator support 8/16-bit SRAM interface configurations split screen display support allowing two different images to be simultaneously displayed virtual display support (displays images larger than the panel size through the use of panning) display modes: black-and-white display 2/4 bits per pixel, 4/16-level gray-scale display 2/4/8 bits per pixel, 4/16/256-level color display two software power-save modes low power consumption display memory interface: 128K bytes using one...
