For engineers reviewing the NT2H1611G0DUDV datasheet, NT2H1611G0DUDV pinout, NT2H1611G0DUDV application, or NT2H1611G0DUDV equivalent, this page provides verified technical context, memory architecture details, RF interface behavior, locking mechanisms, and real-world deployment constraints specific to the NT2H1611G0DUDV variant.

Technical Context

The NT2H1611G0DUDV implements a full ISO/IEC 14443 Type A RF interface with 106 kbit/s data transfer, 16-bit CRC per block, odd parity, and bit coding for robust communication. Its Digital Control Unit manages anticollision, command interpretation (READ, FAST_READ, PWD_AUTH), and state transitions between IDLE, READY1/2, ACTIVE, AUTHENTICATED, and HALT.

This variant uses a 924-byte EEPROM organized in 231 pages of 4 bytes each, with 888 bytes user memory (pages 04h–E1h), static lock bytes at page 02h, dynamic lock bytes at page E2h, and pre-programmed 7-byte UID with BCC0/BCC1 checksums - all optimized for field-programmable read-only protection and NDEF message segmentation.

Key Specifications

Pinout & Package

NT2H1611G0DUDV is supplied as a bare die in FFC Bump format: 8-inch wafer, 120 µm thickness, Au bumps, on film frame carrier with SECS-II electronic fail die marking. It has no conventional pins - connection is made via two antenna terminals (LA and LB) bonded directly to an external coil.

FAQ

What is the exact user memory size of NT2H1611G0DUDV, and how is it structured?

The NT2H1611G0DUDV provides 888 bytes of user Read/Write memory, organized across 222 pages of 4 bytes each (pages 04h to E1h). This memory is distinct from reserved areas: 26 bytes for manufacturer data and configuration, 4 bytes for the Capability Container, and dynamic lock bytes at page E2h. The structure supports NDEF message segmentation and multi-application use without overlap or conflict.

Does NT2H1611G0DUDV support password protection, and how is it implemented?

Yes, NT2H1611G0DUDV supports 32-bit password protection to prevent unauthorized memory operations. Password verification is required before accessing password-protected pages, and the IC enters the AUTHENTICATED state upon successful PWD_AUTH command execution. The password itself is stored in dedicated configuration pages and can be programmed during initialization - with optional limits on unsuccessful attempts to deter brute-force attacks.

How does the dynamic lock mechanism work on NT2H1611G0DUDV?

NT2H1611G0DUDV implements dynamic locking via three lock bytes located at page E2h, covering memory pages starting from 10h onward in 16-page blocks (e.g., pages 10h–1Fh, 20h–2Fh). Each lock bit controls read/write access to its assigned block; once set to logic 1, the lock is irreversible. This enables fine-grained, field-programmable protection of sensitive NDEF payloads without requiring factory reprogramming.

Is NT2H1611G0DUDV compatible with standard NFC smartphones and readers?

Yes, NT2H1611G0DUDV is fully compliant with NFC Forum Type 2 Tag and ISO/IEC 14443 Type A specifications. It operates at 13.56 MHz with 106 kbit/s data transfer and supports standard commands (READ, FAST_READ, PWD_AUTH, GET_VERSION) - ensuring interoperability with all certified NFC smartphones, point-of-sale terminals, and industrial readers without proprietary drivers or firmware.

What is the role of the 7-byte UID and ECC originality signature in NT2H1611G0DUDV?

The NT2H1611G0DUDV features a manufacturer-programmed 7-byte UID (with two BCC checksum bytes) and an ECC-based originality signature. The UID enables unique device identification and NDEF serialization; the ECC signature provides cryptographic proof of genuine NXP silicon - both are read-only, unalterable, and used by host systems to verify tag authenticity and prevent counterfeiting in high-value authentication workflows.
