NXP Semiconductors NT2H1311F0DTLH

Overview

NT2H1311F0DTLH from NXP Semiconductors is an NFC Forum Type 2 Tag compliant contactless IC with 144 bytes of user memory, 13.56 MHz operating frequency, 106 kbit/s data transfer rate, and integrated field detection (FD) pin for wake-up signaling in Bluetooth/Wi-Fi pairing applications.

For engineers reviewing the NT2H1311F0DTLH datasheet, NT2H1311F0DTLH pinout, NT2H1311F0DTLH application, or NT2H1311F0DTLH equivalent, this page delivers verified technical context, exact pin roles, real-world use scenarios, and two confirmed alternative parts - all grounded in NXP's official NTAG213F product documentation (Rev. 3.6, 2015).

Technical Context

The NT2H1311F0DTLH implements a full ISO/IEC 14443 Type A RF interface with integrated rectifier, clock regenerator, and voltage regulator - enabling passive operation powered solely by the reader's RF field. It supports true anticollision and executes commands including FAST_READ, PWD_AUTH, READ_SIG, and HLTA across defined state transitions (IDLE → READY1 → READY2 → ACTIVE → HALT).

Its digital control unit manages EEPROM access, field detection logic (open-drain FD pin configurable for RF presence, SoF, or tag selection trigger), SLEEP mode activation via FD pin grounding, and ECC-based originality signature verification - all within a fixed 4-pin HXSON4 package with no external components required.

Key Specifications

Pinout & Package

NT2H1311F0DTLH uses the HXSON4 package: plastic thermal-enhanced extremely thin small outline, no leads, 4 terminals, body size 2.0 × 1.5 × 0.5 mm. Central pad is recommended floating.

FAQ

What is the primary function of the FD pin on the NT2H1311F0DTLH?

The FD (Field Detect) pin on the NT2H1311F0DTLH is an open-drain output that asserts low when an RF field is detected. It can be configured to trigger on RF presence, Start-of-Frame, or tag selection - serving as a hardware interrupt to wake companion MCUs during NFC-initiated Bluetooth or Wi-Fi pairing sequences. This eliminates polling and reduces system power consumption.

Does the NT2H1311F0DTLH support password-protected memory writes?

Yes, the NT2H1311F0DTLH supports 32-bit password protection to prevent unauthorized memory operations. After successful PWD_AUTH command execution, the IC enters the AUTHENTICATED state, enabling writes to password-protected pages. The password and PACK (password acknowledgment) values are stored in configuration pages 2Bh and 2Ch, respectively.

How much user memory does the NT2H1311F0DTLH provide, and how is it organized?

The NT2H1311F0DTLH provides 144 bytes of freely programmable user memory, organized across 36 pages (04h–27h), with 4 bytes per page. This includes space for NDEF messages, URIs, text records, or custom data. An additional 26 bytes are reserved for manufacturer data, static lock bits, and capability container - all pre-programmed at delivery.

Is the NT2H1311F0DTLH pin-compatible with earlier NXP NFC tags?

Yes, the NT2H1311F0DTLH is fully pin-compatible with the NTAG203F and shares identical HXSON4 package dimensions, pinout (GND/LB/FD/LA), and input capacitance (50 pF). This allows drop-in replacement in existing designs without PCB layout changes, preserving antenna tuning and mechanical fit.

What security features does the NT2H1311F0DTLH include to prevent cloning?

The NT2H1311F0DTLH includes ECC-based originality signature verification, factory-programmed 7-byte UID with BCC0/BCC1 checksums, one-time programmable capability container bits, and field-programmable read-only locking per page. These features collectively ensure cryptographic authenticity and prevent unauthorized duplication or memory tampering in anti-counterfeiting applications.
