SED1336
SED1336 is CMOS GRAPHIC LCD/TV CONTROLLER manufactured by EPSON.
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 microputer, 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 mands that allow the user to create a layered display of characters and graphics. s FEATURES
