NTAG213 KEY FOB

NTAG213, NTAG215 and NTAG216 have been developed by NXP Semiconductors as
standard NFC tag ICs to be used in mass market applications such as retail, gaming and
consumer electronics, in combination with NFC devices or NFC compliant Proximity
Coupling Devices. NTAG213, NTAG215 and NTAG216 (from now on, generally called
NTAG21x) are designed to fully comply to NFC Forum Type 2 Tag (Ref. 2) and
ISO/IEC14443 Type A (Ref. 1) specifications.
Target applications include Out-of-Home and print media smart advertisement, SoLoMo
applications, product authentication, NFC shelf labels, mobile companion tags.
Target use cases include Out-of-Home smart advertisement, product authentication,
mobile companion tags, Bluetooth or Wi-Fi pairing, electronic shelf labels and business
cards. NTAG21x memory can also be segmented to implement multiple applications at
the same time.
Thanks to the high input capacitance, NTAG21x tag ICs are particularly tailored for
applications requiring small footprints, without compromise on performance. Small NFC
tags can be more easily embedded into e.g. product labels or electronic devices.
The mechanical and electrical specifications of NTAG21x are tailored to meet the
requirements of inlay and tag manufacturers.
1.1 Contactless energy and data transfer
Communication to NTAG21x can be established only when the IC is connected to an
antenna. Form and specification of the coil is out of scope of this document.
When NTAG21x is positioned in the RF field, the high speed RF communication interface
allows the transmission of the data with a baud rate of 106 kbit/s.
