10.1 Waiting time before transmitting a response after an EOF from the
For requests where an EEPROM erase and/or programming operation is required, the
transponder IC returns its response when it has completed the write/lock operation. This
will be after 20 ms upon detection of the last falling edge of the interrogator request or
after the interrogator has switched off the field.
RWD
When the HITAG advanced/advanced+ in data exchange mode has detected an EOF of a
valid RWD request or when this EOF is in the normal sequence of a valid RWD request, it
waits for T
to the next slot in an inventory process.
T
Remark: The synchronization on the falling edge from the RWD to the EOF of the HITAG
µ transponder ICs is necessary to ensure the required synchronization of the HITAG µ
transponder IC responses.
