NTAG ( 10 )

Building on NXP’s long-standing leadership in NFC, our NTAG21x passively powered IC solutions work seamlessly with our NFC reader ICs, which are used in more than 90 percent of all NFC-equipped mobile handset models. NTAG21x NFC solutions can store NDEF-formatted data, making them compatible with every NFC-enabled phone and the entire ISO/IEC 14443 infrastructure for contactless smartcards. Our NTAG21x IC portfolio features best-in-class RF performance, a range of memory sizes and smart built-in features - ready for the next generation of inlays and tags. Fast, seamless and easy to use RF interfaces make the NTAG21x IC portfolio particularly well suited for the many new smart media and marketing mass applications being launched worldwide.

The NTAG21xF products offer - on top of the functionality of NTAG21x products - field detection and SLEEP mode, as well as a small footprint package that focuses particularly on electronic applications (i.e. connection handover, Bluetooth simple pairing, Wi-Fi protected set-up, device authentication, gaming and others).

The NTAG I²C is the first product of NXP’s NTAG family offering both contactless and contact interfaces. In addition to the passive NFC Forum compliant contactless interface, the IC features an I²C contact interface which can communicate with a microcontroller. An additional externally powered SRAM mapped into the memory allows fast data transfer between the RF and I²C interfaces and vice versa, without the write cycle limitations of the EEPROM memory. Additionally, the NTAG I²C product can also supply power to external (low power) devices (e.g., a microcontroller) via the embedded energy harvesting circuitry.

NXP’s NTAG family fully complies to NFC Forum Tag specifications, ensuring universal interoperability with NFC devices (e.g., mobile phones, tablet PCs, and fixed readers). Moreover, NXP based NTAG on the ISO 14443A standard, thus allowing easy integration into existing infrastructures using MIFARE and SmartMX. The NTAG family provides varying memory sizes and other special features to allow the user to select the best cost-benefit option for a particular application.
