STMicroelectronics & SAG launch tiny NFC tag for IoT

STMicroelectronics  and Securitag Assembly Group (SAG), a leading supplier of RFID transponders announced a tiny NFC Ferrite Tag that uses STMicroelectronics’ ST25 NFC tag IC for IoT (Internet of Things) data-transmission applications.

Small, light, and thin, the NFC Ferrite Tag can be surface-mounted during production through the metal pad that can be directly soldered to the PCB surface. In addition, the NFC Ferrite tag can function when placed on metal products because of its anti-metallic interference characteristics. These features make it highly attractive for IoT data-transmission applications in consumer electronics, wearable devices, and smart healthcare products. The tiny NFC Ferrite Tag perfectly suits the need for smaller, thinner, and lighter design for wearable products where compactness is critical.

Along with its small dimensions (4.9 x 3.0 x 2.5 mm), the NFC Ferrite Tag with an embedded antenna demonstrates outstanding RF performance, benefiting from ST’s state-of-the-art ST25TA02K NFC Forum Type 4 tag IC with built-in NDEF (NFC Data Exchange Format) message support. This allows the NDEF data to be directly executed through an Android NFC phone without any dedicated application software. In addition to NDEF support, the ST25TA02K features a 20-bit counter and 128-bit password to protect read / write access to the 2Kbit EEPROM memory.

With ST’s global reach and semiconductor leadership, combined with SAG’s professional manufacturing of RFID tags, the two companies aim to accelerate innovation and new product development that strengthens the competitiveness of their customers’ final products.
