Description

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

The reader 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.

A parallel or serial interface can be used for communication between the MCU and reader. When hardware encoders and decoders are used (accelerators for different standards), transmit and receive functions use a 12-byte FIFO register. For direct transmit or receive functions, the encoders/decoders can be bypassed so the MCU can process the data in real time.
