DSFID
Default Storage Scheme for the Tag_ID Page
The Application Family Identifier (AFI) supports a common group-selection mechanism. It is an
8-bit value. The structure and the function are described in ISO 18000-6, and based on ISO/IEC
15962.
The AFI frame shall be used as a low-level hierarchical selection mechanism to separate RF
tags. ATA5590 supports this mechanism as a first group-selection mechanism, including a joker
mechanism. Therefore, the reader can select a tag using this special family structure code. The
joker mechanism is based on the value 00h. If this code is received by the tag, it is selected
automatically.
The data storage format is defined within an 8-bit value. The structure is defined in ISO/IEC
15962 section 7.2.5.
Table 3-1.
Numbering of the access method is defined in ISO/IEC 15961, section 7.1.2.4. The data struc-
ture describes a method, whether or not there is a directory structure on-chip, or how the data is
organized.
The first 13 values for the data format are described in ISO/IEC 15961, section 7.1.2.5.
The DSFID is a special output of this common definition, describing only the Tag_ID structure.
The DSFID information links the data format on a one-to-one basis with the AFI structure, which
enables higher-level and lower-level selection processes.
ATA5590 supports a DSF mechanism according to ISO/IEC 15962 and ISO/IEC 15961 to define
the structure of the ID (DSFID). The 8-bit value is stored by default in the lower byte of the upper
block of the Tag_ID page.
Different Tag_ID structures are supported by ATA5590. These structures can be defined by the
DSFID information. Arbitration, non-unique and private structures are also supported.
ATA5590 supports anticollision procedures which are based on this Tag_ID, whereas the default
anticollision procedure starts with the DSFID information.
The Tag_ID is stored in a 128-bit page of the control memory at page address 00h. It can also
be addressed by a symbolic addressing mechanism (symbolic address 0h). The MSB of the
Tag_ID is located at the MSByte of block 2. In some cases, it contains the header information of
the Tag_ID.
The Tag_ID, the AFI, and the DSFID values have to be set via the system provider or in cooper-
ation with the label or IC manufacturer, and can be protected by a lock bit. The default structure
of the ID page is shown in
