M95020 General 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 1Kbit, 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 2.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).
