Integral IZ6570
The IZ6570 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 IZ6570 family drivers incorporate innovative circuit design strategies to achieve very low power dissipation at a wide range of operating voltages.FEATURES
