CMOS DOT MATRIX LCD CONTROLLER/DRIVER
SED1540
s DESCRIPTION
The SED1540 is an LCD driver-controller intended mainly for segment type liquid crystal displays. The
device communicates with a host microprocessor through an 8-bit parallel data. The SED1540 stores
the data that is sent from the microcomputer in the built-in data display RAM, and generates a liquid
drive signal.
The device is manufactured with a low power consumption CMOS process. These features give the designer
a flexible means of implementing a small to medium size LCD display for a compact, low power system.
