ST7565S
THE MPU INTERFACE (REFERENCE EXAMPLES)
The ST7565S Series can be connected to either 80X86 Series MPUs or to 68000 Series MPUs. Moreover, using the serial
interface it is possible to operate the ST7565S series chips with fewer signal lines.
The display area can be enlarged by using multiple ST7565S Series chips. When this is done, the chip select signal can be
used to select the individual ICs to access.
