Datasheet PDF for the SED1330, around 388 KB, an Epson LCD controller from the same family as the SED1335. It is used in graphic monochrome display modules to handle display memory and panel timing from a host microcontroller. Expect pin definitions, command descriptions, bus timing diagrams and external RAM wiring guidance. Technicians use it to probe the data bus, clock and control lines when a module stays blank. Check the chip marking first, as the newer SED1335 is often substituted and has small differences.
