HITAG μ
ISO 18000 transponder IC
8.2 Memory configuration
The User Configuration Bock consists of one configurable byte (Byte0) and three reserved
bytes (Byte1 to Byte3)
The bits in the User Configuration Block enable a customized memory configuration of the
HITAG μ ISO 18000 transponder ICs.
Three areas (1 to 127bit, 1 to 511 bits and upper memory) can be restricted to read/write
access.
The User Configuration Block (User Config) is programmable by using WRITE SINGLE
BLOCK command at address FFh. Bits 7 to 31 (Byte1 to Byte3) are reserved for further
usage.
The user configuration block (block address FFh) and the password block (block address
FEh) can be locked with the LOCK BLOCK command.
Attention:
The lock of the blocks is permanently and therefore irreversible!

General requirements
The HITAG
μ
ISO 18000 transponder IC is compatible with the ISO 18000-2 standard.
At the time a HITAG
μ
ISO 18000 based transponder is in the interrogator field it doesn’t
respond until it receives a request from the RWD.
All communication from reader to HITAG μ ISO 18000 transponder ICs and vice versa and
the CRC error detection bits (if applicable) are transmitted starting with LSB first.
In the case that multiple HITAG μ ISO 18000 based transponders are in the interrogation
field which cause collisions the RWD has to start the anticollision procedure as described
in this document.
