NXP Semiconductors HT2ICS2002W/V6F:00

Overview

HT2ICS2002W/V6F:00 from NXP Semiconductors is a contactless 125 kHz HITAG 2 transponder IC with 256-bit EEPROM (128-bit user memory), supporting password and crypto authentication modes, and configurable public-mode A/B/C for industrial and animal ID applications. It operates without internal battery via inductive RF coupling and enables bidirectional half-duplex communication with RWDs.

For engineers reviewing the HT2ICS2002W/V6F:00 datasheet, HT2ICS2002W/V6F:00 pinout, HT2ICS2002W/V6F:00 application, or HT2ICS2002W/V6F:00 equivalent, key selection criteria include non-volatile data retention (10 years), 100,000 write cycles, selective memory protection, ASK modulation, and compliance with ISO 11784/11785 in public-mode B.

Technical Context

The HT2ICS2002W/V6F:00 integrates analog RF interface (ASK demodulation/modulation), charge pump, VREG, EEPROM controller, and digital sequencer - all powered solely by the 125 kHz magnetic field. Its digital control block implements half-duplex handshake, reverse-data integrity checking, and mode-dependent memory mapping (e.g., secret key storage in pages 1–2 under crypto mode).

Memory access is governed by configuration byte settings: public-mode A supports MIRO/μEM H400x emulation; public-mode B enables ISO-compliant animal identification; public-mode C provides PIT-compatible PCF793x behavior. All modes support Biphase or Manchester coding for read operations.

FAQ

What is the operating frequency and interface type of HT2ICS2002W/V6F:00?

HT2ICS2002W/V6F:00 operates at 125 kHz using inductive coupling and supports half-duplex ASK-modulated communication. It requires no internal power source - energy and clock are harvested from the reader's magnetic field via an external LC coil connected to LA/LB terminals. The HT2ICS2002W/V6F:00 interface is fully compliant with ISO 11784/11785 in public-mode B and supports Biphase or Manchester coding for read operations.

How is memory organized and protected in HT2ICS2002W/V6F:00?

The HT2ICS2002W/V6F:00 contains 256-bit EEPROM divided into eight 32-bit pages. Pages 0–7 support configurable access: Page 0 holds a read-only 32-bit serial number; Pages 1–2 store secret keys in crypto mode; Page 3 holds configuration and password data; Pages 4–7 are user-programmable. Memory protection is enforced via per-page flags set in the configuration byte - enabling independent read/write locking for security-critical or immutable fields.

Does HT2ICS2002W/V6F:00 support ISO 11784/11785 compliance?

Yes, HT2ICS2002W/V6F:00 achieves full ISO 11784/11785 compliance in public-mode B - the configuration mode explicitly designated for animal identification. This includes standardized 64-bit ID structure, frame format, and modulation timing, ensuring interoperability with certified livestock readers without firmware adaptation. The HT2ICS2002W/V6F:00 datasheet confirms this mode is factory-configurable and functionally validated.

What are the endurance and retention specifications for HT2ICS2002W/V6F:00 EEPROM?

The HT2ICS2002W/V6F:00 EEPROM guarantees 100,000 erase/write cycles and 10 years of data retention at ambient temperatures ≤55 °C. These values are measured and specified in the official NXP short data sheet (Rev. 3.1, 2014) under "Quick reference data" and "Wafer EEPROM characteristics." The HT2ICS2002W/V6F:00 endurance rating applies to all 256 bits, including configuration and secret key pages.

Can HT2ICS2002W/V6F:00 be used in multi-tag environments?

Yes, HT2ICS2002W/V6F:00 supports multi-tag operation through its HALT function - a protocol-level feature that allows a Read Write Device to selectively deactivate addressed transponders after communication. This prevents collisions during inventory reads in dense tag fields, such as palletized logistics or automated gate systems. The HT2ICS2002W/V6F:00 implements this in both password and crypto modes per the functional description in section 7.1.
