Product details
Overview
HT1MOA4S30/E/3J from NXP Semiconductors is a contactless 125 kHz RFID transponder IC implementing the HITAG 1 protocol, featuring 2 kbit EEPROM organized in 64 pages of 4 bytes each, mutual authentication, and AntiCollision (AC) mode for multi-tag operation. It operates without internal battery, deriving power and clock via inductive coupling to a read/write device (RWD), and is used in industrial asset tracking and gas cylinder identification.
For engineers reviewing the HT1MOA4S30/E/3J datasheet, HT1MOA4S30/E/3J pinout, HT1MOA4S30/E/3J application, or HT1MOA4S30/E/3J equivalent, key selection criteria include 125 kHz RF interface compliance, 2 kbit EEPROM endurance (100,000 write cycles), 10-year data retention, selective memory protection, and support for Standard and Advanced protocol modes with 8-bit CRC.
Technical Context
The HT1MOA4S30/E/3J integrates an analog RF interface with rectifier, voltage regulator, and charge pump to generate VDD from the 125 kHz magnetic field; digital control logic handles anticollision sequencing, memory access, and encrypted bidirectional half-duplex communication. Its EEPROM is partitioned into 16 blocks (blocks 0–15), with block 0 containing the configuration page for user-defined memory protection settings.
Advanced Protocol Mode adds extra start bits and appends an 8-bit CRC to read responses-unlike Standard Mode-enhancing data integrity in noisy industrial environments. Memory access supports both page-level (pages 0–63) and block-level (blocks 2–15) operations, while cryptographic functions enable mutual authentication between transponder and RWD.

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 |
|---|---|---|---|
| EM4102 (EM Microelectronic) | Read-only 128-bit ROM; no EEPROM, no encryption, no anticollision - simpler architecture, lower cost. | Limited to static ID applications (e.g., access cards); unsuitable for dynamic logging or secure authentication. | Choose EM4102 only when write capability, memory security, and multi-tag handling are unnecessary. |
| TK4100 (Dongguan Temic) | 125 kHz read/write EEPROM (512 bits), no built-in crypto engine or anticollision - requires external controller for advanced protocols. | Supports basic reprogramming but lacks mutual authentication and AC mode - higher system-level design effort for secure deployments. | TK4100 may reduce unit cost but increases firmware complexity; HT1MOA4S30/E/3J delivers integrated security and protocol handling out-of-box. |
Compared with EM4102 and TK4100, HT1MOA4S30/E/3J provides full protocol stack integration-including anticollision, mutual authentication, and dual-mode operation-reducing host processor overhead and enabling drop-in deployment in regulated industrial tagging systems.

FAQ
What is the operating frequency of the HT1MOA4S30/E/3J transponder IC?
The HT1MOA4S30/E/3J operates at 125 kHz, enabling inductive coupling with standard low-frequency RFID readers and coils. This frequency provides robust performance near metal surfaces and in electrically noisy industrial settings, and is compatible with global LF RFID infrastructure without licensing requirements.
Does the HT1MOA4S30/E/3J require an external power source or battery?
No - the HT1MOA4S30/E/3J is fully passive and derives all operating power from the 125 kHz magnetic field generated by the read/write device (RWD) via its LA/LB coil interface. Its integrated voltage regulator and charge pump condition this harvested energy to power the EEPROM and digital logic during communication.
How is memory organized and protected in the HT1MOA4S30/E/3J?
The HT1MOA4S30/E/3J contains 2 kbit of EEPROM organized into 64 pages (4 bytes each), grouped into 16 blocks. Memory protection is configurable per page or block via the Configuration Page (page 1, block 0), supporting read-only, write-only, one-time-programmable, and secret-key-protected regions - all enforced in hardware.
What distinguishes Standard Mode from Advanced Protocol Mode in the HT1MOA4S30/E/3J?
Advanced Protocol Mode adds extra start bits and appends an 8-bit CRC to read responses - unlike Standard Mode - improving data integrity in EMI-prone environments. Both modes support mutual authentication and anticollision, but Advanced Mode is recommended for industrial automation where read reliability is critical.
Is the HT1MOA4S30/E/3J pin-compatible with other HITAG 1 variants such as HT1ICS3002W/V6F?
No - HT1MOA4S30/E/3J uses the SOT500-2 (MOA4) module carrier package with LA/LB coil terminals, whereas HT1ICS3002W/V6F is a bare die wafer format intended for embedding in custom substrates.
