Datasheet in PDF for the SED1560, a 286 KB document. The SED15xx series are Epson LCD controller and driver chips used in dot-matrix graphic display modules. The sheet normally covers pin functions, the parallel and serial microcontroller interface, command set, internal power circuit and timing diagrams. It is useful when a module shows no contrast or garbage, letting a technician check bias voltages, reset and interface lines. Confirm the chip marking on the module or COG glass before relying on pin numbers.
