Description
The M95128 devices are Electrically Erasable PROgrammable Memories (EEPROMs)
organized as 16384 x 8 bits, accessed through the SPI bus.
The M95128-W can operate with a supply voltage from 2.5 V to 5.5 V, the M95128-R can
operate with a supply voltage from 1.8 V to 5.5 V, and the M95128-DF can operate with a
supply voltage from 1.7 V to 5.5 V, over an ambient temperature range of -40 °C / +85 °C.
The M95128-DF offers an additional page, named the Identification Page (64 bytes). The
Identification Page can be used to store sensitive application parameters which can be
(later) permanently locked in Read-only mode.

The SPI bus signals are C, D and Q, as shown in
selected when Chip Select (S) is driven low. Communications with the device can be
interrupted when the HOLD is driven low.
