NXP NTAG203 Datasheet NTAG203

NFC Forum Type 2 Tag compliant IC with 144 bytes user memory
Datasheet: NTAG203.pdf


RF Interface (ISO/IEC 14443 A)
  • 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)
  • 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
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).
  • 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
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
  • 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.
