1.0 GENERAL DESCRIPTION
1.1 DESCRIPTION
The SED1520 is a dot matrix LCD driver LSI intended for display of characters and graphics. The
bit-addressable display data, which is sent from a microcomputer, is stored in a built-in display data
RAM and generates the LCD drive signal.
The SED1520 incorporates innovative circuit design strategies to assure very low current dissipa-
tion and a wide range of operating voltages. With these features, the SED1520 permits the user to
implement high-performance handy systems operating from a miniature battery.
In order for the user to adaptively configure his system, the SED1520 family offers two application
forms. One form allows an LCD display of 12 characters × 2 lines with an indicator with a single
chip. The other is dedicated to driving a total of 80 segments, enabling a medium-size display to
be achieved by using a minimum number of drivers.
