Summary 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 Table 2 and Figure 1.

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).

In order to meet environmental requirements, ST offers these devices in ECOPACK®

packages.

ECOPACK® packages are Lead-free and RoHS compliant.

ECOPACK is an ST trademark. ECOPACK specifications are available at: www.st.com.
