1. General description
NXP Semiconductors has developed NTAG203F - NFC Forum Type 2 Tag compliant IC -
to be used with NFC enabled devices according to NFC Forum technical specifications
(see Ref. 8 and Ref. 9), according to NFC Forum recommendations or Proximity Coupling
Devices (PCD), according to ISO/IEC 14443A (see Ref. 1). The communication layer (RF
Interface) complies to parts 2 and 3 of the ISO/IEC 14443A standard. The NTAG203F is
primarily designed for NFC Forum Type 2 Tag applications in electronics (i.e. connection
handover, Bluetooth simple pairing, Wi-Fi Protected set-up, device authentication, gaming
and others).
1.1 Contactless energy and data transfer
Communication to NTAG 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. For details on
how to design antennas see Ref. 6.
When the NTAG 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.

7. Functional description
7.1 Block description
The NTAG203F chip consists of the 168 bytes of the total EEPROM memory organized in
42 pages each 4 bytes. 144 bytes (36 pages) are available for the user defined data.
Along with the memory, NTAG203F contains the RF-Interface and the Digital Control Unit.
Energy and data are transferred via an antenna, which consists of a coil with a few turns
directly connected to the LA and LB of the NTAG203F (see Section 5 for details). No
further external components are necessary. (For details on antenna design please refer to
the document Ref. 6 “AN11276 NTAG Antenna Design Guide”.)

For locking of pages starting at page address 10h onwards, lock bytes located in page
28h are used. Those two lock bytes cover the memory area of 96 data bytes together with
configuration area from page address 28h onwards. Therefore, the granularity is larger
then for the first 64 bytes as shown in Figure 7 “Lock bytes 2 and 3”.
The functionality beyond page address 28h which can be locked read-only is:
• the counter
• the lock bytes themselves
