SUMMARY DESCRIPTION
The M95040 is a 4 Kbit (512 x 8) electrically eras-
able programmable memory (EEPROM), access-
ed 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 inter-
face that is SPI-compatible. The bus signals are C,
D and Q, as shown in
Table 2.
and
Figure 2.
.
The device is selected when Chip Select (S) is tak-
en Low. Communications with the device can be
interrupted using Hold (HOLD). WRITE instruc-
tions are disabled by Write Protect (W).
