HITAG μ
Transponder IC
11. State diagram
11.1 General description of states
RF Off
The powering magnetic field is switched off or the HITAG μ transponder IC is out of the
field.
WAIT
After start up phase, the HITAG μ transponder IC is ready to receive the first command.
READY
The HITAG μ transponder IC enters this state after a valid command, except of the STAY
QUIET, SELECT or WRITE-ISO11785 command. If there are several HITAG μ
transponder ICs at the same time in the field of the RWD antenna, the anticollision
sequence can be started to determine the UID of every HITAG μ transponder IC.
SELECTED
The HITAG μ transponder IC enters the Selected state after receiving the SELECT
command with a matching UID. In the Selected state the respective commands with
SEL=1 are valid only for selected transponder.
Only one HITAG μ transponder IC can be selected at one time. If one transponder is
selected and a second transponder receives the SELECT Command, the first transponder
will automatically change to Quiet state.
QUIET
The HITAG μ transponder IC enters this state after receiving a STAY QUIET command or
when he was in selected state and receives a SELECT command addressed to another
transponder.
In this state, the HITAG μ transponder IC reacts to any request commandos where the
ADR flag is set.
ISO 11785 STATE
In this state the HITAG μ transponder IC replies according to the ISO 11785 protocol.
Remark:
In case of an invalid command the transponder will remain in his actual state.
