NTAG213F/216F
NXP Semiconductors
NFC Forum T2T IC with 144/888 bytes user memory and field detection
8. Functional description
8.1 Block description
NTAG21xF ICs consist of a 180 (NTAG213F) or 924 bytes (NTAG216F) EEPROM, RF
interface and Digital Control Unit. Energy and data are transferred via an antenna
consisting of a coil with a few turns which is directly connected to NTAG21xF. No further
external components are necessary. Refer to Ref. 4 for details on antenna design.
• RF interface:
– modulator/demodulator
– rectifier
– clock regenerator
– Power-On Reset (POR)
– voltage regulator
• Anticollision: multiple tags may be selected and managed in sequence
• Command interpreter: processes memory access commands supported by the
NTAG21xF
• EEPROM interface
• NTAG213F EEPROM: 180 bytes, organized in 45 pages of 4 byte per page.
– 26 bytes reserved for manufacturer and configuration data
– 34 bits used for the read-only locking mechanism
– 4 bytes available as capability container
– 144 bytes user programmable read/write memory
• NTAG216F EEPROM: 924 bytes, organized in 231 pages of 4 byte per page.
– 26 bytes reserved for manufacturer and configuration data
– 37 bits used for the read-only locking mechanism
– 4 bytes available as capability container
– 888 bytes user programmable read/write memory
