Description
The M95040 is a 4 Kbit (512 x 8) electrically erasable programmable memory (EEPROM),
accessed by a high speed SPI-compatible bus. The other members of the family (M95020
and M95010) are identical, though proportionally smaller (2 and 1 Kbit, respectively).
Each device is accessed by a simple serial interface that is SPI-compatible. The bus signals
are C, D and Q, as shown in
The device is selected when Chip Select (S) is taken low. Communications with the device
can be interrupted using Hold (HOLD). WRITE instructions are disabled by Write Protect
(W).
