Texas Instruments: TRF7960AEVM Evaluation Module for the TRF7960A Multi-Protocol Fully Integrated 13.56-MHz RFID Writer/Reader IC

The Texas Instruments TRF7960AEVMTRF7960AEVM (Evaluation Module) allows the software application developer to get used to the different functionalities of TRF7960/1 Multi-Standard Fully Integrated 13.56 MHz RFID analog front end and data framing reader system.

• The Texas Instruments multiProductLinkTRF7960 evaluation module (EVM) helps designers evaluate the performance of the TRF7960TRF7960 multiple-protocol RFID transceiver.
• The EVM is used to demonstrate the capabilities of the device (32 pin QFN) and help aid the user in the development process.
• The device incorporates an analog front end, protocol handling, framing, error checking, and multiple integrated voltage regulators with other features that allow the reader to be customized/configurable for the end application.

TheTRF7960TRF7960 Multi-Standard Fully Integrated 13.56-MHz RFID AFE and Data Framing Reader System:

• 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 implemented for communication between the MCU and reader.
• Transmit and receive functions use internal encoders and decoders with 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.
• The transmitter has selectable output power levels of 100 mW (20 dBm) or 200 mW (23 dBm) into a 50- load (5 -V supply) and is capable of ASK or OOK modulation. Integrated voltage regulators ensure power-supply noise rejection for the complete reader system.
• Data transmission comprises low-level encoding for ISO15693, modified Miller for ISO14443-A, high-bit-rate systems for ISO14443 and Tag-it coding systems. Included with the data encoding is automatic generation of SOF, EOF, CRC, and / or parity bits.
• The receiver system enables AM and PM demodulation using a dual-input architecture.
• The receiver system also includes a framing system. This system performs CRC and / or parity check, removes the EOF and SOF settings, and organizes the data in bytes. Framed data is then accessible to the MCU via a 12-byte FIFO register and MCU interface. The framing supports ISO14443 and ISO15693 protocols.
• The TRF7960TRF7960/61 supports data communication levels from 1.8 V to 5.5 V for the MCU I/O interface, while also providing a data synchronization clock. An auxiliary 20-mA regulator (pin 32) is available for additional system circuits.

The TRF7960A Multi-Protocol Fully Integrated 13.56-MHz RFID Writer/Reader IC:
