13 / 86 page  LRI1K Description Doc ID 17170 Rev 3 13/86 1.3 Initial dialogue for vicinity cards The dialog between the vicinity coupling device (VCD) and the vicinity integrated circuit card or VICC (LRI1K) takes place as follows: ● activation of the LRI1K by the RF operating field of the VCD ● transmission of a command by the VCD ● transmission of a response by the LRI1K These operations use the RF power transfer and communication signal interface described below (see Power transfer, Frequency and Operating field). This technique is called RTF (reader talk first). 1.3.1 Power transfer Power is transferred to the LRI1K by radio frequency at 13.56 MHz via coupling antennas in the LRI1K and the VCD. The RF operating field of the VCD is transformed on the LRI1K antenna as an AC voltage which is rectified, filtered and internally regulated. The amplitude modulation (ASK) on this received signal is demodulated by the ASK demodulator. 1.3.2 Frequency The ISO 15693 standard defines the carrier frequency (fc) of the operating field as 13.56 MHz ±7 kHz. 1.3.3 Operating field The LRI1K operates continuously between Hmin and Hmax. ● The minimum operating field is Hmin and has a value of 150 mA/m rms. ● The maximum operating field is Hmax and has a value of 5 A/m rms. A VCD must generate a field of at least Hmin and not exceeding Hmax in the operating volume. |
