Note: These are stress ratings only. Stresses exceeding the range specified under “Absolute Maximum
Ratings” may cause substantial damage to the device. Functional operation of this device at other
conditions beyond those listed in the specification is not implied and prolonged exposure to extreme
conditions may affect device reliability.
Specifications apply for VDD = 3.0V, Ta = 25°C, Freq X’talOSC = 13.560MHz, EN = VDD. Bold values indicate
–20°C to70°C unless otherwise noted. 1kbps data rate 50% duty cycle. RL 50ohm load (matched)
