IZD1520

CMOS DOT MATRIX LCD DRIVER IZD1520 FEATURES CMOS LSI chips Connection with CPU Can be directly coupled with 80-port or 68-port system Available in chip form or in 100-pin plastic QFP Pin-to-Pin Replacement for SED1520 Series Many command set Total 80 (segment+common) drive sets Low power consumption - 30µW maximum at 2kHz external clock Power supply VDD - VSS : 2.4 to -7.0V VDD - V5 : 3.5 to -13.0V DESCRIPTION The IZD1520 family of dot matrix LCD (Liquid Crystal Display) 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 IZD1520 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 IZD1520 which is able to drive two lines of twelve characters each. The IZD1521 which is able to drive 80 segments for extension.
