Product details
Overview
HT2ICS2002W/V6F/RZ from NXP Semiconductors is a contactless 125 kHz HITAG 2 transponder IC with 256-bit EEPROM (128-bit user memory), mutual authentication, and configurable public-mode A/B/C operation for animal ID (ISO 11784/11785) and PIT-compatible applications. It requires no internal battery, draws power via inductive coupling, and supports encrypted read/write in crypto mode.
For engineers reviewing the HT2ICS2002W/V6F/RZ datasheet, HT2ICS2002W/V6F/RZ pinout, HT2ICS2002W/V6F/RZ application, or HT2ICS2002W/V6F/RZ equivalent, key selection criteria include non-volatile data retention (10 years), 100,000 write cycles, Biphase/Manchester coding support, ASK modulation, and wafer-level packaging for embedding in RFID tags and industrial identification modules.
Technical Context
The HT2ICS2002W/V6F/RZ implements a fully integrated analog RF interface with on-chip voltage regulation, charge pump, and demodulation circuitry - enabling passive operation from a 125 kHz magnetic field. Its digital control block manages half-duplex communication, memory access sequencing, and cryptographic operations using dedicated secret key pages (Pages 1–2 in crypto mode).
Memory organization is mode-dependent: in password mode, Page 1 stores the RWD password; in crypto mode, Pages 1–2 hold the 48-bit secret key; Page 3 contains the 8-bit configuration byte and 24-bit tag password. All eight 32-bit pages support selective read/write protection via memory flags.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
HT2ICS2002W/V6F/RZ is supplied as a sawn wafer on FFC (flexible film carrier), 150 µm thick, 8-inch diameter, UV-treated and inkless - designated MOA4 package per NXP documentation. No discrete pins; terminals LA and LB connect directly to the external resonant coil.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LA | RF antenna input terminal A | Connects to one end of external LC resonator; forms part of 125 kHz tank circuit with LB. |
| LB | RF antenna input terminal B | Connects to other end of external LC resonator; completes inductive coupling path for power and data transfer. |
Key Features
| Feature | Design Value |
|---|---|
| Mutual authentication | Prevents unauthorized access via challenge-response protocol using stored secret key - essential for secure casino and high-value asset tagging. |
| Configurable public modes | Three factory-selectable read-only modes (A/B/C) enable drop-in replacement for µEM H400x, ISO-compliant animal ID tags, and PCF793x-based PIT systems. |
| Selective memory protection | Per-page read/write flags allow granular access control - e.g., lock serial number (Page 0) while permitting updates to user data (Pages 4–7). |
| No internal power source | Full energy harvesting from 125 kHz RF field eliminates battery dependency - critical for maintenance-free, multi-decade deployments in gas cylinder ID. |
| HALT function for multi-tag operation | Enables collision avoidance in dense RFID environments by allowing readers to selectively disable transponders after initial response. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HT2DC20S20/F/R | SOT385-1 plastic leadless module carrier package; same die, different form factor and thermal profile. | Requires PCB mounting instead of wafer embedding; better suited for surface-mount tag assemblies than implantables. | Choose HT2DC20S20/F/R when mechanical robustness and automated assembly are prioritized over minimal thickness or direct coil integration. |
| HT2MOA4S20/E/3/R | SOT500-2 PLLMC tape-and-reel package; identical wafer die but pre-mounted on 35 mm wide carrier tape. | Optimized for high-volume automated tag manufacturing with pick-and-place; lacks direct FFC flexibility of HT2ICS2002W/V6F/RZ. | Choose HT2MOA4S20/E/3/R for reel-fed production lines where wafer handling and singulation are already integrated into the process flow. |
Compared with HT2DC20S20/F/R and HT2MOA4S20/E/3/R, the HT2ICS2002W/V6F/RZ offers direct wafer-level integration for ultra-thin, custom-shaped RFID tags - making it optimal for applications demanding minimal profile, environmental sealing, or direct coil bonding without intermediate substrates.

FAQ
What is the operating frequency and modulation type supported by HT2ICS2002W/V6F/RZ?
The HT2ICS2002W/V6F/RZ operates exclusively at 125 kHz using ASK (Amplitude Shift Keying) modulation for backscatter communication. It supports both Biphase and Manchester coding schemes for read operations, ensuring compatibility with legacy and modern RWDs. This frequency and modulation combination enables reliable short-range inductive coupling without external power sources - a defining feature of the HT2ICS2002W/V6F/RZ.
Does HT2ICS2002W/V6F/RZ require an external power supply or battery?
No, the HT2ICS2002W/V6F/RZ is a fully passive transponder that derives all operating power from the 125 kHz magnetic field generated by the Read Write Device. Its integrated rectifier, voltage regulator, and charge pump convert RF energy into stable DC supply - eliminating the need for batteries or wiring. This self-powered operation is fundamental to the HT2ICS2002W/V6F/RZ's use in maintenance-free, long-lifecycle applications like livestock tags and gas cylinder ID.
How is memory organized and protected in HT2ICS2002W/V6F/RZ?
The HT2ICS2002W/V6F/RZ contains 256 bits of EEPROM organized into eight 32-bit pages. Access rights (read-only, read/write, or locked) are controlled per page via configuration flags. In crypto mode, Pages 1–2 store the 48-bit secret key; Page 3 holds the configuration byte and tag password. This structure allows selective protection - for example, locking Page 0 (serial number) while enabling updates to Pages 4–7 (user data) - a capability confirmed in the HT2ICS2002W/V6F/RZ functional description.
Which ISO standards does HT2ICS2002W/V6F/RZ support for animal identification?
The HT2ICS2002W/V6F/RZ supports ISO 11784 and ISO 11785 through its factory-configurable public-mode B. This mode delivers standardized 64-bit animal identification codes with built-in error detection, enabling direct interoperability with certified livestock readers and national traceability databases. Public-mode B is explicitly documented as a core feature of the HT2ICS2002W/V6F/RZ in NXP's short data sheet.
What package type is HT2ICS2002W/V6F/RZ delivered in, and how is it mounted?
The HT2ICS2002W/V6F/RZ is delivered as a sawn wafer on flexible film carrier (FFC), 150 µm thick, 8-inch diameter, UV-treated and inkless - also referenced as MOA4 package. It has no leads or solder pads; instead, terminals LA and LB are bonded directly to an external resonant coil using conductive adhesive or wire bonding. This wafer format enables ultra-thin, custom-shaped RFID tags - a key differentiator of the HT2ICS2002W/V6F/RZ versus module-based alternatives.
