-V version), 2.5 V (for the -W version), and down
to 1.8 V (for the -R version of each device).
The M95256 and M95128 are available in Plastic
Dual-in-Line, Plastic Small Outline and Thin Shrink
Small Outline packages.
Each memory device is accessed by a simple
serial interface that is SPI bus compatible. The bus
signals are C, D and Q, as shown in Table 1 and
Figure 3.
The device is selected when the chip select input
(S) is held low. Communications with the chip can
be interrupted using the hold input (HOLD).
