1.3 Description
The TRF7963A is an integrated analog front end and data-framing device for a 13.56-MHz RFID
reader/writer system. Built-in programming options make it suitable for a wide range of applications for
proximity identification 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.
Comprehensive documentation, reference designs, evaluation modules, and TI microcontrollers (based on
MSP430™ or ARM™ technology) source code are available.
The TRF7963A is a high-performance 13.56-MHz HF RFID reader IC comprising an integrated analog
front end (AFE) and a built-in data framing engine for ISO14443A/B and FeliCa. It supports data rates up
to 848 kbps for ISO14443 with all framing and synchronization tasks on board (in ISO Mode, default). The
TRF7963A also supports NFC Forum Tag Types 1, 2, 3, and 4 operations (as reader/writer only). This
architecture enables the customer to build a complete and cost-effective yet high-performance HF
RFID/NFC reader/writer using a low-cost microcontroller (for example, an MSP430).
Other standards and even custom protocols can be implemented by using two of the Direct Modes the
device offers. These Direct Modes (0 and 1) allow the user to fully control the analog front end (AFE) and
also gain access to the raw subcarrier data or the unframed, but already ISO formatted data and the
associated (extracted) clock signal.
