ST7522

17 x 96 Dot Matrix LCD Controller/Driver

OVERVIEW

FEATURES

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.

Fast 8-bit MPU interface compatible with 80- and

68- family microcomputers and serial interface

Clock synchronous serial interface

Many command set

Display data Read/Write, display ON/OFF,

Normal/Reverse display mode, page address set ,

column address set , status read , display all

points ON/OFF, LCD bias set, electronic volume,

read/modify/write, segment driver direction select,

power saver, static indicator, adjustable OSC

frequency, booster input voltage select, follower

input voltage and amplified ratio selectable

4 static indicator and 96 icon available

Total 118 (segment + common + static) drive sets

Wide range of supply voltages
