ST25 NFC/RFID Reader and Dynamic Tag Solutions

ST Microelectronics' ST25R and ST25DV offer a comprehensive set of NFC and RFID solutions

Image of STMicrolectronics' ST25 NFC/RFID Reader and Dynamic Tag Solution ST Microelectronics offers the ST25R NFC high-performance reader with unique features such as automatic antenna tuning, capacitive and inductive wake-up, very high and dynamic output power, and high sensitivity. It communicates with the ST25D dynamic NFC and RFID tags accessible by either RF or I2C bus, capable of fast transfer mode and energy harvesting.

ST25R: High-Performance HF Reader/NFC Initiator

The ST25R HF RFID/NFC reader series provides multiprotocol support for 13.56 MHz NFC/RFID communications such as ISO 14443 Type A or B, ISO 15693, ISO 18092, FeliCa, and NFC Forum protocols. ST Microelectronics' NFC reader ICs and chips integrate a serial peripheral interface (SPI) to communicate with a host microcontroller.

Thanks to its outstanding performances and unique features, the NFC universal device ST25R3916 is ideal for payment applications and is a perfect fit for a large variety of consumer and industrial applications, including access control, gaming, IoT, pairing, brand protection, product configuration, authentication, traceability, among others.

ST25DV: Dynamic NFC and RFID Tags IC - ISO15693 and NFC Forum Type 5 Compliant

The ST25DV series of dynamic NFC/RFID tags offer a 13.56 MHz long-range interface compatible with NFC phones and readers. Based on an ISO/IEC 15693 and NFC Forum Type 5 tag, ST25DV tag ICs can be operated from an RFID reader or an NFC phone. They include an I2C interface that lets them connect to a host, such as MCU or MPU. These tags feature an innovative fast transfer mode between an embedded host and an NFC phone or reader thanks to their half-duplex 256-byte buffer. ST25DV dynamic NFC/RFID tags can be used in a wide variety of applications, including consumer electronics, industrial, metering, electronic shelf labels, IoT objects, and more.
