SED1336
s DESCRIPTION
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.
