1.3 Description
The TRF7964A is an integrated analog front end and data-framing device for a 13.56-MHz RFID system.
Built-in programming options make it suitable for a wide range of applications for proximity and vicinity
identification systems.
Built-in user-configurable programming options make it suitable for a wide range of applications. The
TRF7964A 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 TI MCU (MSP430, ARM) source code are available.
