DESCRIPTION
Power supply VDD - VSS : 2.4 to -7.0V
VDD - V5 : 3.5 to -13.0V
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 extention.

Notes:
1. All voltages are specified relative to VDD = 0V.
2. The following relation must be always hold
VDD V1 V2 V3 V4 V5.
3. Exceeding the absolute maximum ratings may cause permanent damage to
the device. Functional operating under these
conditions is not implied.
