9.2 System Overview
Figure 84 shows the SED1330F/1335F/1336F in a
typical system. The microprocessor issues instruc-
tions to the 1330F/SED1335F/1336F, and the
SED1330F/1335F/1336F drives the LCD panel and
may have up to 64Kbytes of display memory.
Since all of the LCD control circuits are integrated
onto the SED1330F/1335F/1336F, few external com-
ponents are required to construct a complete me-
dium-resolution liquid crystal display.
