SED1500 Series

CMOS DOT MATRIX LCD CONTROLLER DRIVER

■ DESCRIPTION

The SED1500 Series is a dot matrix LCD driver CMOS LSI with the ability of alpha-numeric and graphic

display. The device stores the parallel data that is sent from the microcomputer in a built-in data RAM and

generates a liquid drive signal. The LSI can be connected directly to the 4-bit/8-bit microcomputer. The

SED1500 Series is suitable to applications involving low speed, large capacity. The device consumes only

a little current because it is operated by a low-frequency clock so that, by combining it with a CMOS

microcomputer unit, a battery driven, long life system can be built at low cost.
