SED1278
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 5×8 pixel
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.
FEATURES
• Interface for 4- and 8-bit MPUs
• Display RAM – 80 bytes (80 characters)
• Character generator ROM – 240 characters
– 5×8 pixel font
• Character genrator RAM – 64 bytes
– 5×8 pixel font, 8 characters.
– 5×10 pixel font, 4 characters.
• Number of characters used
