The TRF7960A device is an integrated analog front-end (AFE) and multiprotocol data-framing device for a 13.56-MHz RFID reader/writer system that supports ISO/IEC 14443 A and B, Sony FeliCa, and ISO/IEC 15693. Built-in programming options make it suitable for a wide range of applications for proximity and vicinity 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.
The TRF7960A device supports data rates up to 848 kbps with all framing and synchronization tasks for the ISO protocols onboard. The device also supports reader/writer mode for NFC Forum tag types 1, 2, 3, 4, and 5. NFC Forum tag types 2, 3, 4, and 5 are supported with the built-in protocol decoders used in Direct Mode 2. NFC Forum tag type 1 requires the use of Direct Mode 0. Other standards and custom protocols can also be implemented by using Direct Mode 0. Direct Mode 0 lets the user fully control the AFE and also gain access to the raw subcarrier data or the unframed, but already ISO-formatted, data and the associated (extracted) clock signal.
The receiver system has a dual-input receiver architecture to maximize communication robustness. The receivers also include various automatic and manual gain control options. The received signal strength from transponders, ambient sources, or internal levels is available in the RSSI register.
A SPI or parallel interface can be used for the communication between the MCU and the TRF7960A reader. When the built-in hardware encoders and decoders are used, transmit and receive functions use a 12-byte FIFO register. For direct transmit or receive functions, the encoders or decoders can be bypassed so the MCU can process the data in real time.
The TRF7960A device supports a wide supply voltage range of 2.7 V to 5.5 V and data communication levels from 1.8 V to 5.5 V for the MCU I/O interface.
The transmitter has selectable output power levels of 100 mW (+20 dBm) or 200 mW (+23 dBm) equivalent into a 50-Ω load when using a 5-V supply and supports OOK and ASK modulation with selectable modulation depth.
The built-in programmable auxiliary voltage regulator delivers up to 20 mA to supply an MCU and additional external circuits within the reader system.
