DLR-TL001 Memory Description
Address space
The DLR-TL001 TAG implements a standard Gen2 memory map; it has 4
memory banks: EPC - TID - RESERVED - USER. Below is a brief explanation of
memory banks' content (all the address are specified 16 bit word bounded):
EPC.
This bank contains 16 bit CRC-16 and 16 bit PC field according to the
standard and additional 496 bit for EPC storing. The EPC bank contains the
EPC of the DLR-TL001 product that is composed by the Datalogic company
prefix, the DLR-TL001 object type and a serial number. The EPC is formatted
as a SGTIN-96 code.
TID.
This bank contains the Class Identifier, the Mask-Designer Identifier,
the Model Number of the chip as requested by the standard, plus a 32 bit
long Serial Number (see below for details) and the assembly and chip revi-
sion. Total size of the TID field is 64 bits. Th
e TID memory bank contains
also a 32 bit SAM field used to store the address of the sensor characteris-
tics table as defined by th
e ISO18000 6REV1 draft standard and additional
110 bytes for user purposes. The TID and SAM fields are "permalocked" by
the manufacturer while the additional user space is not locked by default but
it can be locked using the standard Gen2 lock mechanism.

RESERVED. This bank contains the 32 bit Kill password and the 32 bit Access
password according to the EPC Class 1 Gen 2 standard. The RESERVED mem-
ory bank contains additional 56 bytes for user purposes. The locking mech-
anism of the user data field in a RESERVED me
mory bank is linked to the
locking of the Access password field (i.e. user data is locked when the access
password is locked). Data stored in these 56 bytes are protected also for
reading as the password fields are, when locked.
