Absolute Maximum Ratings

Logic Supply Voltage ....................................................................................................... 2V to 3.6V

Logic Input Voltage ........................................................................................VSS-0.3V to VDD+0.3V

Storage Temperature ..................................................................................................-55°C to 150°C

Operating Temperature ................................................................................................-40°C to 85°C

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)
