SED1336
s DESCRIPTION
CMOS GRAPHIC LCD/TV CONTROLLER
For Medium-Scale LCD
Output to LCD-Screen
Virtual Screen Display RAM
Enhanced Control Function
•• Simultaneous LCD & TV Display
The SED1336 is a CMOS low-power dot matrix liquid crystal graphic display controller with built-in TV
support. The built-in TV support IC is capable of displaying characters and graphic images simultaneously
on TV monitors and flat panels.
The SED1336 has a built-in TV control circuit that generates either NTSC or PAL system synchronous
signals, memory. The device stores the display data in external SRAM that is sent by an 8-bit microcomputer,
and generates all the control signals required by the LCD drivers.
The controller incorporates an internal character generator ROM which supports user-defined characters. An
external CG ROM can also be supported to provide additional characters.
The SED1336 can be interfaced to high-speed microprocessors such as the Intel 80xx family or the Motorola
68xx family. The controller supports a set of commands that allow the user to create a layered display of
characters and graphics.

1. The humidity resistance of the flat package may be reduced if the package is immersed in solder. Use a soldering technique
that does not heatstress the package.
2. If the power supply has a high impedance, a large voltage differential can occur between the input and supply voltages. Take
appropriate care with the power supply and the layout of the supply lines.
3. All supply voltages are referenced to VSS = 0V.
