SED1330 Datasheet | EPSON

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 microputer, 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 mands 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 - Selectable MPU interface is patible with both the Intel family and the Motorola 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 × 8 or 8 × 16 pixel characters Allows mixing of ROM and RAM character sets - Supports 64K bytes of memory: 2 of 32K × 8 100ns SRAM or 8 of 8K × 8 100ns SRAM - Display duty 1/2 to 1/256 - Low power dissipation 5m A (typical) 0.05µA (typical), standby - Logic power supply 4.5 to 5.5V - Package Plastic QFP5-60 pin (FBA) Plastic QFP6-60 pin (FBB) s SYSTEM BLOCK DIAGRAM DATA CPU CONTROL SED1330F 68xx 80xx SRAM VA0 to VA15 VCE VR/W VD0 to VD7 YSCL,YDIS LP, WF XSCL, XECL XD0 to XD3 SED1330 s BLOCK DIAGRAM Video RAM CG RAM External CG ROM VRAM...
