1.0 Overview
1.1 Description
The SED1330/1335F/1336F is a family of versatile
LCD controller ICs that can display text and graphics
on a medium size LCD panel. The software is
compatible among all three chips. S-MOS recom-
mends new designs use the SED1335 since the
SED1330 will gradually be replaced by the SED1335.
The SED1336F incorporates a TV sync generator
circuit that is compatible with both NTSC and PAL
systems. The 256 × 200 pixel TV display comprises
three superimposed layers, and is identical to the
simultaneous LCD panel display. When driving an
LCD only, up to 3 overlapping layers can be displayed
on LCD panels up to 640 × 256 pixels in size. The
SED1330/1335F does not incorporate a TV controller.
The SED1330/1335F/1336F can display layered text
and graphics, scroll the display in any direction and
partition the display into multiple screens.
The SED1330/1335F/1336F stores text, character
codes and bit-mapped graphics data in external frame
buffer memory. Display controller functions include
transferring data from the controlling microprocessor
to the buffer memory, reading memory data, convert-
ing data to display pixels and generating timing sig-
nals for the buffer memory, TV monitor and LCD
panel.
The SED1330/1335F/1336F has an internal charac-
ter generator with 160, 5 × 7 pixel characters in
internal mask ROM. The character generators sup-
port up to 64, 8 × 16 pixel characters in external
character generator RAM and up to 256, 8 × 16 pixel
characters in external character generator ROM.
