| SED1330 CMOS GRAPHIC LCD CONTROLLER This part is replaced by SED1335. Some pin differences between SED1330 and SED1335 exist. Please check SED1335 data sheet. S-MOS Systems, Inc., will continue to support existing designs which use SED1330. s 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. s FEATURES * CMOS low-power graphic and character display controller interface is compatible * Selectable MPUand the Motorola family with both the Intel family * Smooth scrolling support: * * Horizontal and vertical scroll Scrolling of selected areas of the display Multimode display: 2 layers of overlapping character and graphics 3 layers of overlapping graphics Selectable display synthesis: Inverse video Flashing display, cursor on/off/blink Under and bar cursor, block cursor Simple animation * Programmable cursor * Internal character generator ROM * Supports external character generator ROM: * * * * * 8 x 8 or 8 x 16 pixel characters Allows mixing of ROM and RAM character sets Supports 64K bytes of memory: 2 of 32K x 8 100ns SRAM or 8 of 8K x 8 100ns SRAM Display duty .................................. 1/2 to 1/256 Low power dissipation ................ 5mA (typical) 0.05A (typical), standby Logic power supply ........................ 4.5 to 5.5V Package ................
