TRF7970AEVM: RFID and NFC

The Texas Instruments TRF7970A evaluation module (EVM) is intended to be used by to demonstrate the capabilities of the TRF7970A and help aid in the development process by providing a working hardware / firmware reference example for traditional HF (13.56 MHz) RFID and also NFC Forum operations.

The TRF7970A EVM features include:

Support for:

• ISO15693 standard based transponders

• ISO14443 standard based transponders (Types A and B)

• NFC Forum modes (RFID reader\writer, peer to peer, and card emulation)

FeliCa™ based transponders (UID read only)

Standalone polling mode for quick demonstration of transponder detection

Communication with host software graphical user interface (GUI) via USB VCP

The TRF7970A EVM also has the following hardware features specifically for development purposes:

MSP430F2370 ultra-low power microcontroller with JTAG connectivity to development environment for custom firmware development.

Parallel or SPI connectivity via 0-? jumpers

Logic analyzer/oscilloscope test points for relevant signal observation during code development

SMA (edge mount and through-hole) pads for connecting customer designed magnetic dipole circuit
