SED1335
CMOS GRAPHIC LCD CONTROLLER
For Medium-Scale LCD
Low Operating Voltage 2.7 to 5.0V
On-Chip Character Generator ROM
s DESCRIPTION
The SED1335 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 SED1335 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.
