Product details
Overview
HT2ICS2002W/V6F/RV from NXP Semiconductors is a contactless 125 kHz HITAG 2 transponder IC designed for secure RFID identification in battery-free, inductively powered systems. It integrates 256-bit EEPROM (128-bit user memory + 128-bit control/secret memory), supports mutual authentication, and operates in password mode, crypto mode, or three public read-only modes (A/B/C) - including ISO 11784/11785-compliant animal ID and PIT-compatible PCF793x emulation.
For engineers reviewing the HT2ICS2002W/V6F/RV datasheet, HT2ICS2002W/V6F/RV pinout, HT2ICS2002W/V6F/RV application, or HT2ICS2002W/V6F/RV equivalent, key selection criteria include its wafer-level packaging (sawn 8-inch FFC, 150 µm), 10-year data retention, 100,000 write cycles, dual coding support (Manchester/Biphase), and ASK modulation with half-duplex handshake integrity.
Technical Context
The HT2ICS2002W/V6F/RV implements an analog RF interface with integrated rectifier, voltage regulator, and charge pump to derive power and clock from a 125 kHz magnetic field. Its digital core includes a sequencer, EEPROM interface, access control logic, and RF interface control - enabling secure read/write operations without external components beyond the coil.
Memory organization is page-based (8 pages × 32 bits), with configurable access rights per page via configuration byte and secret key storage in Pages 1–2 (crypto mode) or password storage in Page 1 (password mode). The device supports selective read/write protection, HALT functionality for multi-tag operation, and emulates legacy transponders including µEM H400x and PIT PCF793x families.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless 125 kHz transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HT2DC20S20/F/R | SOT385-1 plastic leadless module package (3.2 × 3.2 mm); includes pre-mounted coil and encapsulation - ready-to-use vs. wafer-level HT2ICS2002W/V6F/RV. | Preferred for rapid prototyping or low-volume OEM assemblies where coil integration and mechanical robustness are prioritized over miniaturization. | Select HT2DC20S20/F/R when eliminating coil winding and tuning steps; HT2ICS2002W/V6F/RV suits custom antenna designs and ultra-thin implantables. |
| HT2MOA4S20/E/3/R | SOT500-2 PLLMC tape-and-reel package (35 mm wide tape); same die but in plastic module carrier format - different mechanical mounting and handling than wafer-on-FFC. | Targeted at high-volume automated assembly lines requiring standard SMT-compatible carriers and reel-fed placement. | Choose HT2MOA4S20/E/3/R for SMT production scalability; HT2ICS2002W/V6F/RV requires custom die-bonding and wire bonding processes. |
Compared with HT2DC20S20/F/R and HT2MOA4S20/E/3/R, the HT2ICS2002W/V6F/RV offers maximum design flexibility for custom coil geometry and ultra-low-profile embedding - but requires full RF front-end development, whereas the alternatives integrate mechanical and antenna elements for faster time-to-market.

FAQ
What is the operating frequency and modulation scheme supported by HT2ICS2002W/V6F/RV?
The HT2ICS2002W/V6F/RV operates at 125 kHz using ASK (Amplitude Shift Keying) modulation for uplink communication to the reader. It supports both Manchester and Biphase coding schemes for downlink data reception, ensuring compatibility with diverse RWD platforms and legacy infrastructure. This combination delivers robust performance in noisy industrial settings without requiring an internal clock source.
Does HT2ICS2002W/V6F/RV require external components to function?
No - the HT2ICS2002W/V6F/RV requires only an external LC resonant coil connected between LA and LB terminals. All power regulation, clock generation, demodulation, modulation, EEPROM control, and security logic are fully integrated. This eliminates external capacitors, regulators, crystals, or memory ICs, reducing system BOM and PCB footprint for compact or implantable designs.
How is memory organized and protected in HT2ICS2002W/V6F/RV?
The HT2ICS2002W/V6F/RV contains 256 bits of EEPROM organized into eight 32-bit pages. Access rights (read-only, read/write, or locked) are set per page via configuration flags and secret keys. In crypto mode, Pages 1–2 store 48-bit secret keys; in password mode, Page 1 holds the RWD password. Serial number (Page 0) is factory-programmed and read-only, ensuring unalterable device identity.
What are the environmental and reliability specifications for HT2ICS2002W/V6F/RV?
The HT2ICS2002W/V6F/RV guarantees 10 years of data retention at ambient temperatures ≤55 °C and withstands 100,000 erase/write cycles. Its absolute maximum junction temperature is +140 °C, and it meets MIL-STD-883D ESD testing (2 kV HBM). As a wafer-level device, it relies on end-product encapsulation for mechanical and moisture protection per final application requirements.
Can HT2ICS2002W/V6F/RV emulate legacy transponders?
Yes - HT2ICS2002W/V6F/RV supports three public read-only modes: public-mode A (MIRO/µEM H400x), public-mode B (ISO 11784/11785 for animal ID), and public-mode C (PIT-compatible PCF793x). These modes require no reader firmware changes and deliver identical response formats, enabling seamless migration from older transponders while retaining full read/write capability when needed.
