HF NTAG203 NFC Forum Type 2 Tag

NXP Semiconductors has developed NTAG203 - NFC Forum Type 2 Tag compliant IC - to be used with NFC enabled devices according to NFC Forum technical specifications (see Ref. 9 and Ref. 10), according to NFC Forum recommendations or Proximity Coupling
Devices (PCD), according to ISO/IEC 14443A (see Ref. 2). The communication layer (RF Interface) complies to parts 2 and 3 of the ISO/IEC 14443A standard. The NTAG203 is primarily designed for NFC Forum Type 2 Tag applications (i.e. Smart Advertisement,
connection handover, Bluetooth simple pairing, WiFi Protected set-up, call request, SMS, goods and device authentication and others).

Features and benefits

1 RF Interface (ISO/IEC 14443A)

 Contactless transmission of data and supply energy (no battery needed)
 Operating distance: up to 100 mm (depending on field strength and antenna geometry)
 Operating frequency: 13.56 MHz
 Fast data transfer: 106 kbit/s
 High data integrity: 16-bit CRC, parity, bit coding, bit counting
 True anticollision
 7 byte serial number (cascade level 2 according to ISO/IEC 14443-3)

2 EEPROM

 168 bytes of total memory, divided in 42 pages (4 bytes each)
 144 bytes of user r/w memory area, divided in 36 pages (4 bytes each)
 Field programmable read-only locking function per page for first 64 bytes
 Field programmable read-only locking function per block
 32-bit user definable One-Time Programmable (OTP) area
 16-bit counter
 Data retention of 5 years
 Write endurance 10000 cycles

3 NFC Forum Tag 2 Type compliance

NTAG203 IC provides full compliance to the NFC Forum Tag 2 Type technical specification (see Ref. 9) and enables NDEF data structure configurations (see Ref. 10).

4 Security

 Anti-cloning support by unique 7-byte serial number for each device
 32-bit user programmable OTP area
 Field programmable read-only locking function per page for first 512 bits
 Read-only locking per block for rest of memory

5 Cascaded UID

The anticollision function is based on an IC individual serial number called Unique IDentifier. The UID of the NTAG203 is 7 bytes long and supports cascade level 2 according to ISO/IEC 14443-3.

6 Anticollision

An intelligent anticollision function according to ISO/IEC 14443 allows to operate more than one card in the field simultaneously. The anticollision algorithm selects each card individually and ensures that the execution of a transaction with a selected card is
performed correctly without data corruption resulting from other cards in the field.
