Description
The M95256, M95256-W, M95256-R and M95256-DR are electrically erasable
programmable memory (EEPROM) devices. They are accessed by a high speed SPI-
compatible bus. Their memory array is organized as 32768 × 8 bits.
The M95256-DR also offers an additional page, named the Identification Page (64 bytes)
which can be written and (later) permanently locked in Read-only mode. This Identification
Page offers flexibility in the application board production line, as the Identification Page can
be used to store unique identification parameters and/or parameters specific to the
production line.
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 taken low. Communications with the device
can be interrupted using Hold (HOLD).

As EEPROM cells loose their charge (and so their binary value) when exposed to ultra violet
(UV) light, EEPROM dice delivered in wafer form or in WLCSP package by
ST Microelectronics must never be exposed to UV light.
