... The ST7556 Series can be connected to either 80X86 Series MPUs or to 6800 Series MPUs. Moreover, using the serial interface it is possible to operate the ST7556 series chips with fewer signal lines. The display area can be enlarged by using multiple ST7556 Series chips. When this is done, the chip select signal can be used to select the individual ICs to access. ...
