INTRODUCTION
The ST7528 is a driver & controller LSI for 16-level gray scale graphic dot-matrix liquid crystal display systems. It contains
2 Mode (160X100,132X128) for Segment and Common driver circuits. This chip is connected directly to a microprocessor,
accepts Serial Peripheral Interface (SPI), IIC or 8-bit parallel display data and stores in an on-chip display data RAM of 160
x 129 x 4 bits. It performs display data RAM read/write operation with no external operating clock to minimize power
consumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a
display system with the fewest components.

... The ST7528 Series can be connected to either60X86 Series MPUs or to 6800Series MPUs. Moreover, using the serial interface it is possible to operate the ST7528 series chips with fewer signal lines. The display area can be enlarged by using multiple ST7528 Series chips. When this is done, the chip select signal can be used to select the individual ICs to access. ...
