(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating

Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

All voltages are referenced to VSS.

(3)

For soldering during board manufacturing, it is required to follow the current JEDEC J-STD-020 specification with peak reflow

temperatures not higher than classified on the device label on the shipping boxes or reels.

(1)

JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(2)

JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

(2)

Tank quality factor

(1)

The coil inductance of the antenna LRES with the external capacitance CTune plus the device internal capacitance CIN is a resonant

circuit. The resonant frequency of this LC circuit must be close to the carrier frequency fc:

fRES = 1 / [2π(LRESCRES)

1/2] = 1 / [2π(L

RES(CIN+CTune))

1/2] ≈ f

(2)

For CIN refer to Section 4.9.3.
