13.56MHz NXP Plastic NFC Smart Card Ntag203 , 0.7mm Substrate Thickness

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 , according to NFC Forum recommendations or Proximity Coupling Devices (PCD), according to ISO/IEC 14443A. 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).

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. 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

4. 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.
