From the time the VCD has generated the rising edge of an EOF:

•

If this EOF is 100% modulated, the VCD waits for a time at least equal to t3min for 100%

modulation before sending a new EOF.

•

If this EOF is 10% modulated, the VCD waits for a time at least equal to t3min for 10%

modulation before sending a new EOF.

1. The tolerance of specific timings is ± 32/fC.

2. VCD request will not be interpreted during the first milliseconds following the RF field rising.

3. t1max does not apply for write-alike requests. Timing conditions for write-alike requests are defined in the

command description.

4. tSOF is the time taken by the ST25DVxxx to transmit an SOF to the VCD. tSOF depends on the current data

rate: High data rate or Low data rate.

5. tNRT is the nominal response time of the ST25DVxxx. tNRT depends on VICC to ST25DVxxx data rate and

subcarrier modulation mode.
