OVERVIEW
The SED1278 is a dedicated character display controller/
driver which, when used with the SED1181F or the
SED1681 segment drivres, is able to display up to 80
characters under 4- or 8-bit MPU control.
The internal character generator (CG) ROM has an
extended 240, 5
×10 pixel, character set, plus CGRAM
space for an additional eight user definable 5

characters. These memory features combined with the
rich set of control instructions offer the potential for a
highly flexible character display system.
The SED1278 features a guaranteed minimum LCD
drive voltage of 3 V making it suitable for use with low
voltage LCD panels.
