DESCRIPTION
The KKD1520 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 KKD1520 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 KKD1520 which is able to drive two lines of twelve characters each.
The IZD1521 which is able to drive 80 segments for extension.

Notes:
1.
All voltages are specified relative to V_DD = 0V.
2.
The following relation must be always hold
V_DD ≥ 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.
