NTAG213F/216F
NXP Semiconductors
NFC Forum T2T IC with 144/888 bytes user memory and field detection
The following conditions apply if part of the memory is password protected for read
access:
• if NTAG21xF is in the ACTIVE state
– if any requested page address is equal or higher than AUTH0 a NAK is replied
• if NTAG21xF is in the AUTHENTICATED state
– the FAST_READ command behaves like on a NTAG21xF without access
protection
Remark: PWD and PACK values can never be read out of the memory. When reading
from the pages holding those two values, all 00h bytes are replied to the NFC device
instead.
Remark: The FAST_READ command is able to read out the whole memory with one
command. Nevertheless, receive buffer of the NFC device must be able to handle the
requested amount of data as there is no chaining possibility.
