Communication

The device communication is done via the CAN-FD. The CAN Bus can be configured to allow for CAN-HS operation only up to 1Mbps.

The device also provides an SPI bus and UART bus to make it suitable for integration by OEMs. It can be integrated into charging stations, access control, system identification devices, etc.

Product Description

The RFID /NFC reader (P3501) is a multiprotocol data-framing device for a 13.56-MHz NFC/RFID system supporting all three NFC operation modes – reader/writer, peer-to-peer, and card emulation according to ISO/IEC 14443 A and B, Sony FeliCa, ISO/IEC 15693, NFCIP-1 (ISO/IEC 18092), and NFCIP-2 (ISO/IEC 21481). Built-in programming options make the device suitable for a wide range of applications for NFC, proximity, and vicinity identification systems.

The device supports data rates up to 848 kbps with all framing and synchronization tasks for the ISO protocols onboard. The TRF7970A device also supports reader and writer mode for NFC Forum tag types 1, 2, 3, 4, and 5. Other standards and even custom protocols can be implemented by using one of the direct modes the device offers. These direct modes let the user fully control the AFE and 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.

The CAN Bus interface can be used for the communication with the module or via SPI bus for OEM integrated application. Transmit and receive functions use a 127-byte FIFO register. For direct transmit or receive functions, the encoders or decoders can be bypassed so the device can process the data in real time.

The transmitter has selectable output power levels of 100 mW (+20 dBm) or 200 mW (+23 dBm). Integrated RF field detector with programmable wake-up levels, eight selectable power modes, and ultralow power operation enable easy development of robust and cost-efficient designs for long battery life.

The internal memory allows for the device to store internally many IDs without the need to check against an external memory.

The nanoSense can bring several benefits to your application by:

·         Reducing the complexity of installing sensors.

·         Improving data accessibility for outside systems.

·         Simplify the integration of sensors into the control chain.

·         Optimize on-board data management

The RFID / NFC reader comes in compact, open or waterproof enclosures that makes it easier to install them in constrained environments. The connection system, identical to all sensors and readers, simplifies the installation and maintenance of systems.

This device can be used inside infrastructure equipment, automotive, robots, maritime or land, hobby, or commercial applications. It can be used to validate design, take punctual measurements, or used a warning or trigger system for an acquisition system or to continuously try new ideas. They can be used in many industries across many disciplines, in the lab, field, classroom, or embedded in machinery.
