Note:
Identification page
The M24C02-DRE offers an Identification Page (16 bytes) in addition to the 2-Kbit 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.
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.
