General description
Designed to be the perfect enabler for NFC in home-automation and consumer
applications, this feature-packed, second-generation connected NFC tag is the fastest,
least expensive way to add tap-and-go connectivity to just about any electronic device.
NXP NTAG I C
plus
is a family of connected NFC tags that combine a passive NFC
2
interface with a contact I C interface. As the second generation of NXP’s industry leading
connected-tag technology, these devices maintain full backward compatibility with first-
2
generation NTAG I C products, while adding new, advanced features for password
protection, full memory-access configuration from both interfaces, and an originality
signature for protection against cloning.
The second-generation technology provides four times higher pass-through performance,
2
along with energy harvesting capabilities, yet NTAG I C
plus
devices are optimized for
use in entry-level NFC applications and offer the lowest BoM of any NFC solution.
I C and NFC communications are based on simple, standard command sets, and are
augmented by the demo board OM5569/NT322E, which includes online reference source
code. All that is required is a simple antenna design (see
Ref. 5),
with no or only limited
extra components, and there are plenty of reference designs online for inspiration. NTAG

I C
plus
development board is certified as NFC Forum Type 2 Tag (Certification ID:
58514).
