Application family identifier (AFI)
The AFI (application family identifier) represents the type of application targeted by the VCD
and is used to identify, among all the M24LR04E-Rs present, only the M24LR04E-Rs that
meet the required application criteria.
Figure 47. M24LR04E-R decision tree for AFI
The AFI is programmed by the M24LR04E-R issuer (or purchaser) in the AFI register. Once
programmed and locked, it can no longer be modified.
The most significant nibble of the AFI is used to code one specific or all application families.
The least significant nibble of the AFI is used to code one specific or all application
subfamilies. Subfamily codes different from 0 are proprietary.
(See ISO 15693-3 documentation.)
