■ DESCRIPTION

The SED1330 is a CMOS low-power dot matrix liquid crystal graphic display controller. The device stores in external RAM display data sent by an 8-bit microcomputer, and generates all the signals required by the LCD drivers. The LSI incorporates an internal character generator ROM which supports user-defined characters (also an external CGROM can be supported).

The SED1330 can be interfaced to high-speed microprocessors such as the Intel family or Motorola family. The controller supports a set of rich commands that will allow the user to create a layered display of characters and graphics.

Also, the controller functions as a pipeline buffer between the MPU and display memory so that low-cost, medium-speed SRAM can be used.
