NTAG213F/216F
NXP Semiconductors
NFC Forum T2T IC with 144/888 bytes user memory and field detection
A roll-over mechanism is implemented to continue reading from page 00h once the end of
the accessible memory is reached. Reading from address 2Ah on a NTAG213F results in
pages 2Ah, 2Bh, 2Ch and 00h being returned.
The following conditions apply if part of the memory is password protected for read
access:
• if NTAG21xF is in the ACTIVE state
– addressing a page which is equal or higher than AUTH0 results in a NAK response
– addressing a page lower than AUTH0 results in data being returned with the
roll-over mechanism occurring just before the AUTH0 defined page
• if NTAG21xF is in the AUTHENTICATED state
– the 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.
