Description

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 used for communication between the MCU and reader. When hardware encoders and decoders are used (accelerators for different standards), transmit and receive functions use 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 (at 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 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 also includes an automatic gain control option and selectable gain. Also included is a selectable bandwidth to cover a broad range of input subcarrier signal options. The received signal strength for AM and PM modulation is accessible via the RSSI register. The receiver output is selectable among a digitized subcarrier signal and any of ten integrated subcarrier decoders (two for ISO15693 low bit rate, two for ISO15693 high bit rate, two for ISO14443, three for ISO14443 high bit rates and one for Tag-it systems). Selected decoders also deliver bit stream and a data clock as outputs.

The receiver system also includes a framing system. This system performs the 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 TRF7960/61 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.
