Write Identification Page (M24C64-D only)
The Identification Page (32 bytes) is an additional page which can be written and (later)
permanently locked in Read-only mode. The Identification Page is written by issuing an
Write Identification Page instruction. This instruction uses the same protocol and format as
Page Write (into memory array), except for the following differences:
●
●
LSB address bits A4/A0 define the byte address inside the Identification Page.
If the Identification Page is locked, the data bytes transferred during the Write Identification
Page instruction are not acknowledged (NoAck).
