M95020-DWDW4TP/K

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 device is selected when Chip Select is taken Low. Communications with the device can be interrupted using Hold . WRITE instructions are disabled by Write Protect (W).
