NT3H2111/NT3H2211
NFC Forum Type 2 Tag compliant IC with I²C interface
10. NFC Command
NTAG activation follows the ISO/IEC 14443-3 Type A specification. After NTAG I²C plus
has been selected, it can either be deactivated using the ISO/IEC 14443 HALT command,
or NTAG commands (e.g. READ_SIG, PWD_AUTH, SECTOR_SELECT, READ or
WRITE) can be performed. For more details about the card activation refer to Ref. 2.

[1] Unless otherwise specified, all commands use the coding and framing as described in Ref. 1.
10.2 Timing
The command and response timing shown in this document are not to scale and values
are rounded to 1 s.
All given command and response times refer to the data frames, including start of
communication and end of communication. They do not include the encoding (like the
Miller pulses). An NFC device data frame contains the start of communication (1
“start bit”) and the end of communication (one logic 0 + 1-bit length of unmodulated
carrier). An NFC tag data frame contains the start of communication (1 “start bit”) and the
end of communication (1-bit length of no subcarrier).
The minimum command response time is specified according to Ref. 1 as an integer n,
which specifies the NFC device to NFC tag frame delay time. The frame delay time from
NFC tag to NFC device is at least 87 s. The maximum command response time is
specified as a time-out value. Depending on the command, the T_ACK value specified for
command responses defines the NFC device to NFC tag frame delay time. It does it for
either the 4-bit ACK value specified or for a data frame.
