SED1278

OVERVIEW

FEATURES

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.

• Interface for 4- and 8-bit MPUs

• Display RAM – 80 bytes (80 characters)

• Character generator ROM – 240 characters
