USB NFC integrated reader solution

[1]

Ipd is the total currents over all supplies.

[2]

IDD(PVDD) depends on the overall load at the digital pins.

[3]

IDD(SVDD) depends on the overall load on VDD(SVDD) pad.

[4]

IDD(TVDD) depends on VDD(TVDD) and the external circuitry connected to TX1 and TX2.

[5]

During operation with a typical circuitry the overall current is below 100 mA.

10.1.2 Voltage regulator characteristics

[1]

The internal regulator is only enabled when the USB interface is selected by I0 and I1.

10.2 Antenna presence self test thresholds

The values in Table 9 are guaranteed by design. Only functional is done in production for

cases andet_ithl[1:0] = 10b and for andet_ithh[2:0] = 011b.
