HITAG μ
Transponder IC
8.
General requirements
The HITAG
μ
transponder ICs are compatible with ISO 11785. At the time a HITAG
μ
transponder IC is in the interrogator field it will respond according to ISO 11785.
A HITAG
μ
advanced/advanced+ can be identified as a transponder being in the data
exchange mode (advanced mode) by the type information in the reserved bit field sent to
the RWD.
Bit 15 of the ISO 11784 frame shall be set to ’1’ indicating that this is an HITAG μ
advanced/advanced+ in data exchange mode.
Bit 16 of the ISO 11784 frame (additional data flag set to ’1’, indicating that the
HITAG μ advanced/advanced+ in data exchange mode contains additional data in the
user memory area.
To bring the HITAG μ transponder ICs into the data exchange mode, the RWD needs to
send a valid request or a valid switch command within the defined listening window.
A HITAG μ transponder IC in data exchange mode only responds when requested by the
RWD (RTF mode).
The identification code, all communication from reader to HITAG μ 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 advanced/advanced+ in data exchange mode are in the
interrogation field which cause collisions the RWD has to start the anticollision procedure
as described in this document. Depending in which part of the ISO 11785 timing frame the
collision is detected the RWD will start with the anticollision request.
The HITAG
μ
transponder IC in data exchange mode switches back to the standard
ISO 11785 mode when it :
is no longer in the interrogation field
has terminated the data exchange mode operations and the interrogation field was
switched off for at least 5 ms afterwards

HITAG
μ
transponder IC air interface
9.1 Downlink description
To transfer the HITAG μ transponder ICs into the data exchange mode, the RWD's
interrogation field needs be switched off. After this off-period, the interrogation field is
switched on again, and either the SOF at the start of a valid request or the special switch
command needs to be sent to the HITAG μ transponder IC within the specified switch time
window. The HITAG μ transponder IC switches itself into the data exchange mode upon
reception of any of the switch commands. In this mode, the HITAG μ transponder IC
respond when requested by the RWD (reader driven protocol).
The HITAG μ transponder IC in data exchange mode switches back to the ISO 11785
mode after the interrogation field has been switched off for at least 5 ms.
