Product details
Overview
M24LR04E-RMC6T/2 from STMicroelectronics is a dual-interface Dynamic NFC/RFID tag IC integrating 4-Kbit EEPROM, ISO 15693 RF interface, I²C bus (400 kHz), and energy harvesting capability. It operates from 1.8 V to 5.5 V, supports RF write-in-progress indication via RF WIP/BUSY pin, and delivers 53 kbit/s fast-mode RF data rate. Used in smart packaging, asset tagging, and industrial maintenance logs where battery-free operation and dual-access memory are required.
For engineers reviewing the M24LR04E-RMC6T/2 datasheet, M24LR04E-RMC6T/2 pinout, M24LR04E-RMC6T/2 application, or M24LR04E-RMC6T/2 equivalent, key selection criteria include ISO 15693 compliance, I²C + RF concurrent access, 4-Kbit EEPROM organization (512 bytes I²C / 128×32-bit RF blocks), energy harvesting analog output (Vout), and ECOPACK2® UFDFPN8 package compatibility.
Technical Context
The M24LR04E-R implements a dual-protocol architecture: ISO 15693-compliant 13.56 MHz RF interface with Manchester-coded load modulation (423/484 kHz subcarriers) and standard two-wire I²C interface supporting 400 kHz clock rate. Its internal tuning capacitance (27.5 pF) enables direct antenna coupling without external matching components.
Memory is partitioned into RF-accessible 32-bit blocks and I²C-addressable byte space, with independent password protection schemes-single password for I²C writes and multi-sector password control for RF mode. The RF WIP/BUSY pin provides real-time status feedback during contactless write operations, while Vout supplies harvested RF energy to external circuitry at configurable sink current ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dynamic NFC/RFID tag applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST25DV04K-IER | Same ST25 family; identical 4-Kbit EEPROM, ISO 15693, I²C, and energy harvesting-but adds I²C interrupt (INT) pin and extended RF command set (e.g., Fast Write). | Supports interrupt-driven host wake-up and faster bulk RF writes; better suited for high-throughput logistics scanning. | Select when requiring hardware interrupt signaling or >53 kbit/s RF throughput; pinout differs (INT added, Vout repurposed). |
| NXH3670UK | NXP HF RFID tag IC with 2-Kbit EEPROM, ISO 15693, and energy harvesting-but no I²C interface; RF-only access with proprietary command extensions. | Lacks dual-interface capability; relies entirely on RF for all memory access-no local MCU co-processing support. | Choose only for pure-contactless applications where local microcontroller integration is unnecessary and cost sensitivity outweighs flexibility. |
Compared with ST25DV04K-IER, M24LR04E-RMC6T/2 offers simpler system integration without interrupt handling overhead but lacks fast-write acceleration. Versus NXH3670UK, it enables hybrid wired/wireless architectures critical for edge intelligence in industrial IoT nodes.

FAQ
What is the maximum RF data rate supported by M24LR04E-RMC6T/2?
The M24LR04E-RMC6T/2 supports up to 53 kbit/s using Fast commands (e.g., Fast Read Single Block), enabled by optimized Manchester coding with dual subcarriers. Standard ISO 15693 modes deliver 6.6 kbit/s (low rate) and 26 kbit/s (high rate). This 53 kbit/s capability is confirmed in Section 9.3 and Table 20 of the official datasheet (DocID022208 Rev 11).
Can the I²C and RF interfaces operate simultaneously without conflict?
Yes-the M24LR04E-RMC6T/2 uses physically separate memory maps: I²C accesses 512-byte linear address space, while RF accesses 128×32-bit blocks. No arbitration logic is required, and concurrent access is electrically isolated. This architecture is explicitly defined in Sections 3 and 7 of the datasheet and verified in application note AN4914.
How is energy harvesting implemented, and what load can Vout drive?
Vout is an analog output pin delivering harvested RF energy from the AC0/AC1 antenna terminals. It supports four configurable sink current ranges (1.5 mA, 3 mA, 6 mA, 12 mA) set via the Control Register (Section 4.3.2). The pin is not intended to power high-current peripherals but reliably biases low-power sensors or resets companion logic-validated per Figure 27 in the datasheet.
Is the 64-bit UID truly unique and factory-programmed?
Yes-the 64-bit UID is laser-trimmed during final test and permanently stored in ROM. It is read-only, cannot be altered by I²C or RF commands, and serves as a cryptographic anchor for authentication. UID format and read procedure are fully specified in Section 13 and Table 21 of DocID022208 Rev 11.
