Description
The M95512-W, M95512-R and M95512-DR are electrically erasable programmable
memory (EEPROM) devices accessed by a high-speed SPI-compatible bus. In the rest of
the document these devices are referred to as M95512, unless otherwise specified.
The memory array is organized as 65536 × 8 bit. The device is accessed by a simple serial
interface that is SPI-compatible. The bus signals are C, D and Q, as shown in
Figure
The device is selected when Chip Select (S) is taken low. Communications with the device
can be interrupted using Hold (HOLD).
