SED1565 Series
THE MPU INTERFACE (REFERENCE EXAMPLES)
The SED1565 Series can be connected to either 80 × 86 Series MPUs or to 68000 Series MPUs. Moreover, using the
serial interface it is possible to operate the SED1565 series chips with fewer signal lines.
The display area can be enlarged by using multiple SED1565 Series chips. When this is done, the chip select signal can
be used to select the individual ICs to access.
