RFID Reader/Writer 32-Pin VQFN EP T/R

The TRF7964A device is an integrated analog front end and data-framing device for a 13.56-MHz RFID system. Built-in programming options make the device suitable for a wide range of applications for proximity and vicinity identification systems. Built-in user-configurable programming options make the device suitable for a wide range of applications. The TRF7964A device 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. Documentation, reference designs, EVM, and source code TI MSP430 MCUs or ARM MCUs are available.
