SED1520 Series

OVERVIEW

The SED1520 family of dot matrix LCD drivers are designed for the display of characters and graphics. The drivers generate LCD drive signals derived from bit mapped data stored in an internal RAM.

The drivers are available in two configurations

The SED1520 family drivers incorporate innovative circuit design strategies to achieve very low power dissipation at a wide range of operating voltages.

These features give the designer a flexible means of implementing small to medium size LCD displays for compact, low power systems.

•The SED1520 which is able to drive two lines of twelve characters each.

•The SED1521 which is able to drive 80 segments for extention.

•The SED1522 which is able to drive one line of thirteen characters each.

FEATURES

•Fast 8-bit MPU interface compatible with 80- and 68- family microcomputers

•Many command set

•Total 80 (segment + common) drive sets

•Low power — 30 μW at 2 kHz external clock

•Wide range of supply voltages

VDD – VSS: –2.4 to –7.0 V

VDD – V5: –3.5 to –13.0 V

• Low-power CMOS
