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.
