Overview
ST Sitronix OVERVIEW The ST7522 family of dot matrix LCD 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 drivers are available in two configurations The ST7522 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 ST7522 which is able to drive 1 line of 6 Chinese characters or 2 lines of 12 Chinese characters each line with two ST7522.
