Description
The M95M02-DR devices are electrically erasable programmable memory (EEPROM)
devices. They are accessed by an SPI-compatible bus. Their memory array is organized as
262 144 × 8 bits. It can also be seen as 1024 pages of 256 bytes each.
The M95M02-DR devices also offer an additional page, named the Identification Page
(256 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.
Figure 1.
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).
