Identification page

The M24M02-A125 offers an Identification Page (256 byte) in addition to the 2 Mb memory.

The Identification page contains two fields:

•

Device identification code: the first three bytes are programmed by STMicroelectronics

with the Device identification code, as shown in Table 4.

•

Application parameters: the bytes after the Device identification code are available for

application specific data.

Note:

If the end application does not need to read the Device identification code, this field can be

overwritten and used to store application-specific data. Once the application-specific data

are written in the Identification page, the whole Identification page should be permanently

locked in Read-only mode.

The instructions Read, Write and Lock Identification Page are detailed in Section 4:

Instructions.
