IZD1520U MATRIX LIQUID CRYSTAL DISPLAY CONTROLLER DRIVER
CMOS chips Connection with directly coupled with 80-port 68-port system Available chip form 100-pin plastic Pin-to-Pin Replacement SED1520 Series Many command Total (segment+common) drive sets power consumption 30µW maximum 2kHz external clock Power supply -7.0V -13.0V
DESCRIPTION IZD1520 family matrix (Liquid Crystal Display) drivers designed display characters graphics. drivers generate drive signals derived from mapped data stored internal RAM. IZD1520 family drivers incorporate innovative circuit design strategies achieve very power dissipation wide range operating voltages. These features give designer flexible means implementing small medium size displays compact, power systems. IZD1520 which able drive lines twelve characters each. IZD1521 which able drive segments extention. ABSOLUTE MAXIMUM RATINGS
Characteristic Supply Voltage Supply Voltage Supply Voltage Input Voltage Output Voltage Power Dissipation Operating Temperature Storage Temperature Soldering temperature time max) Symbol Tstg Tsol Value 16.5 Unit
Notes:
voltages specified relative following relation must always hold Exceeding absolute maximum ratings cause permanent damage device. Functional operating under these conditions implied.
