Explorer Kit, Android, NFC tag
This User Manual describes the functionalities and how to use the
Android and PC application of the NTAG I
2
C
plus
Explorer kit. Both
applications provide the same functionality and have the same look and
feel so this User Manual is valid for both.

NTAG I²C plus Explorer Kit - Android Demo
1. Object
NTAG I
2
C
plus
Explorer kit is an all-in-one demonstration and development resource to
demonstrate the unique properties of the NTAG I
2
C
plus
connected tag. By including a
full complement of hardware and software tools, users can investigate the capabilities of
the chip through the various demonstrations, develop and test their own applications
(with additional LPC-Link2 debug probe
1
).
This User Manual explains how to use the NTAG I
2
C
plus
demo application for Android.
The Windows app is not detailed in this User Manual since it provides identical
functionalities as the Android app, therefore the same User Manual is valid.
Technical aspects related to the IC features are beyond the scope of this document. To
get further technical details please consult the dedicated Datasheet “NTAG I
2
C
plus,
NFC
Forum Type 2 Tag compliant IC with I
2
C interface” (refer to [NTAGI2Cplus]).

NTAG I²C plus Explorer Kit - Android Demo
2. NTAG I
2
C
plus
introduction
The NTAG I
2
C
plus
part of NXP’s NTAG family offering both contactless and contact
interfaces. In addition to the passive NFC Forum compliant RF interface, the NTAG I
2
C
plus
provides an I
2
C interface that allows the IC to communicate with the microcontroller
when the chip is powered by an external device, i.e. a NFC mobile phone.
The NTAG I
2
C
plus
operating in energy harvesting mode provides the possibility to
supply external low power devices (e.g. microcontrollers) with the energy generated from
the RF field of the external NFC device.

NTAG I
2
C
plus
The NTAG I
2
C
plus
product has two types of memories:
1. EEPROM memory compliant with the NFC Forum Type 2 Tag implementation.
2. 64-byte SRAM memory, which is mapped to the EEPROM memory and it is
externally powered.
The NTAG I
2
C
plus
features a pass-through mode that allows fast download and upload
of data from the RF interface to the I
2
C interface and vice versa. This functionality makes
use of the SRAM memory that allows fast data transfer between interfaces without the
EEPROM performance limitations.
In addition to the I
2
C interface functionality, the NTAG I
2
C
plus
product features an Event
Detection pin for waking up the connected host devices or synchronizing the data
transfer between the two interfaces.
The NTAG I
2
C
plus
offers the possibility to protect the memory access. This protection is
done by authenticating the tag with a password. When the tag is protected,
authentication is needed to access the memory. The NTAG I
2
C
plus
also improves the
speed when writing into the SRAM memory.
