(1)  The absolute maximum ratings under any condition is limited by the constraints of the silicon process. 
      Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions
      for extended periods may degrade device reliability. These are stress ratings only and functional operation of
      the device at these or any other conditions beyond those specified are not implied
(2) The maximum junction temperature for continuous operation is limited by package constraints. Operation
     above this temperature may result in reduced reliability and/or lifetime of the device.


Description

The TRF7960/61 is an integrated analog front end & data framing system for a 13.56 MHz RFID reader  system. Built-in programming options make it suitable for a wide range of applications both in  proximity and vicinity RFID systems.

The reader of TRF7960 TRF7960 is configured by selecting the desired  protocol in the control registers. Direct access to all  control registers allows fine tuning of various reader  parameters as needed.
