TRF7970A Description

Short technical summary and product information.

The TRF7970A from Texas Instruments is a highly integrated analog front-end and data-framing device designed for 13.56-MHz NFC and RFID systems. It supports multiple NFC operation modes, including reader/writer, peer-to-peer, and card emulation, adhering to standards such as ISO/IEC 14443 A and B, Sony FeliCa, ISO/IEC 15693, NFCIP-1 (ISO/IEC 18092), and NFCIP-2 (ISO/IEC 21481).

 

Key features include integrated encoders, decoders, and data framing for NFC initiator, active, and passive target operations across three bit rates (106 kbps, 212 kbps, 424 kbps). The device offers programmable output power up to +23 dBm (200 mW) and programmable I/O voltage levels from 1.8 VDC to 5.5 VDC. It operates within a wide input voltage range of 2.7 VDC to 5.5 VDC and features programmable power modes for ultra-low-power system design, with power down consumption less than 1 µA.

 

The TRF7970A includes a dual receiver architecture with RSSI for improved performance and an RF field detector for collision avoidance and passive transponder emulation. It is available in a 32-pin QFN package measuring 5 mm x 5 mm, suitable for compact designs. The operating temperature range is -40°C to 110°C.

 

This transceiver IC is well-suited for applications such as mobile devices, secure pairing, ticketing systems, payment readers, product identification, access control, and sharing electronic business cards.
