SUMMARY DESCRIPTION
These electrically erasable programmable memo-
ry (EEPROM) devices are accessed by a high
speed SPI-compatible bus.
The
M95320-S are 32Kbit devices organized as 4096
x 8 bits. The M95640, M95640-W, M95640-R and
M95640-S are 64Kbit devices organized as 8192
x 8 bits.

The device is accessed by a simple serial interface
that is SPI-compatible. The bus signals are C, D
and Q, as shown in
The device is selected when Chip Select (S) is tak-
en Low. Communications with the device can be
interrupted using Hold (HOLD).
The devices are available in three different ver-
sions identified by a specific marking (see
2.).
