ISO/IEC 16353:2011 specifies commands for the Near Field Communication Wired Interface (NFC-WI) specified in ISO/IEC 28361. The commands allow exchange of control and state information between the transceiver and the front-end.

Overview

ISO/IEC 16353:2011 specifies the front-end configuration command set for the Near Field Communication Wired Interface (NFC-WI) defined in ISO/IEC 28361. Commonly referred to as NFC-FEC, this standard defines the command and response formats, state machine extensions, checksum rules, frame encoding and timing required to exchange control and state information between a transceiver and an RF front-end.

This standard was prepared by Ecma International (as ECMA-390) and adopted by ISO/IEC JTC 1. Conformance requires implementation of the mandatory parts of ISO/IEC 16353 and the referenced NFC-WI specification (ISO/IEC 28361).

Key Topics

States and sub-states: NFC-FEC extends NFC-WI with Escape, Command Ready, Command Busy and Quit sub-states to manage command submission and response handling.

Command & response format: An 8-bit header, optional data field (arbitrary length) and an 8-bit checksum. The checksum is the bytewise XOR of the initialization vector (0xFF), the header and data.

Command set: Includes control commands such as CMD_QUIT, CMD_NOP; RF commands CMD_RF_ON and CMD_RF_OFF; mode selection commands (Initiator passive/active and Target modes at various data rates); register/block read and write (CMD_WR, CMD_RR, CMD_WB, CMD_RB); and status query (CMD_GS).

Responses: Defined headers for RES_ACK (ACK), RES_NACK (NACK) and RES_DATA (data). If a response other than ACK is received where ACK/NACK is expected, it is treated as NACK. The response timeout for all commands is 2 ms.

Information transfer & framing:

Transceiver frames use Manchester encoding and f/128 bit coding as per ISO/IEC 28361; Start-of-communication is ONE and End-of-communication is HIGH for one bit duration.
Front-end frames use Modified Miller encoding and f/128 bit coding; Start-of-communication is ZERO and End-of-communication is ZERO followed by no gating for two bit durations.

Parity: An odd parity bit is used so that the number of ONEs in each transmitted byte plus parity is odd.

Applications

Implementers and integrators use ISO/IEC 16353 to:

Control RF field state (RF on/off) from a host or transceiver

Switch communication modes and data rates between transceiver and front-end

Perform register and block read/write operations for configuration and diagnostics

Exchange status and diagnostic data using RES_DATA and CMD_GS

This standard is relevant for NFC chipset vendors, firmware engineers, module integrators and test labs implementing NFC-WI wired interfaces.

Related Standards

ISO/IEC 28361:2007 - Near Field Communication Wired Interface (NFC-WI) - normative reference for encoding, bit coding and base conventions.

ECMA-390 - Origin of the NFC-FEC specification; ISO/IEC 16353 was prepared by Ecma and adopted under a fast-track procedure.

For implementation, follow the mandatory command encodings, checksum calculation and the 2 ms response timeout. Adherence ensures reliable control and state exchange between transceiver and front-end across NFC-WI implementations.
