Product details

Overview

M24LR16E-RMN6T/2 from STMicroelectronics is a dual-interface Dynamic NFC/RFID tag IC integrating 16-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 64-bit UID and multi-level password security for industrial asset tagging and smart packaging applications.

For engineers reviewing the M24LR16E-RMN6T/2 datasheet, M24LR16E-RMN6T/2 pinout, M24LR16E-RMN6T/2 application, or M24LR16E-RMN6T/2 equivalent, key selection criteria include RF data rate (up to 53 kbit/s with Fast commands), EEPROM endurance (1M cycles at 25°C), energy harvesting sink current configurability, ISO 15693 compliance, and dual-mode memory organization (2048 bytes I²C / 512 × 32-bit RF blocks).

Technical Context

The M24LR16E-R implements a true dual-interface architecture: its I²C port enables direct microcontroller read/write access to EEPROM while the contactless interface complies fully with ISO 15693 and ISO 18000-3 Mode 1 standards. The RF path uses load modulation with Manchester coding and supports both low (6.6 kbit/s) and high (26 kbit/s) data rates, plus 53 kbit/s in Fast command mode.

Internally, it features separate memory mapping for I²C (byte-addressable) and RF (32-bit block-oriented) access, with independent password protection schemes-single password for I²C writes and multiple sector-level passwords for RF operations. The integrated 27.5 pF tuning capacitance simplifies antenna matching for 13.56 MHz operation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-interface NFC/RFID tag applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ST25DV16K-IER	Same ST25 family; 16-Kbit EEPROM; adds I²C interrupt pin and dynamic register for enhanced event handling	Better suited for real-time host notification (e.g., RF write completion interrupt); requires additional GPIO	Select when system demands deterministic host response to RF events rather than polling RF WIP/BUSY
NXH3670UK/N1	NXP HF RFID tag IC with 2-Kbit EEPROM; no I²C interface; supports ISO 14443-A only (not ISO 15693)	Limited to contactless-only use; lacks local MCU interface and energy harvesting output	Choose only for pure NFC Forum Type 2 tag applications where I²C access and power harvesting are unnecessary

Compared with ST25DV16K-IER, M24LR16E-RMN6T/2 offers simpler GPIO usage and proven energy harvesting but lacks interrupt-driven host signaling; versus NXH3670UK/N1, it provides full dual-interface flexibility and field-powered operation at the cost of higher pin count and complexity.

FAQ

What is the maximum RF data rate supported by the M24LR16E-RMN6T/2?

The M24LR16E-RMN6T/2 supports three RF data rates: 6.6 kbit/s (low), 26 kbit/s (high), and 53 kbit/s using Fast commands. The 53 kbit/s mode requires compatible ISO 15693 readers and reduces inventory time significantly compared to standard modes, as confirmed in Section 9 and Table 20 of the official datasheet.

How does the energy harvesting function work, and what are its design limits?

The Vout pin delivers harvested RF energy from the 13.56 MHz field, with sink current configurable in four ranges (1.5 mA, 3 mA, 6 mA, or 12 mA). It powers external circuitry such as sensors or signal conditioners without batteries. Maximum output depends on field strength and antenna coupling - typical usable power is ≤1 mW under standard reader conditions.

Can the M24LR16E-RMN6T/2 be used with standard ISO 15693 readers without firmware modification?

Yes. The M24LR16E-RMN6T/2 is fully compliant with ISO 15693 and ISO 18000-3 Mode 1 standards, including mandatory commands (Inventory, Read Single Block, Write Single Block) and optional ones (Fast Inventory, Fast Read). No reader firmware changes are needed for basic operation, though Fast command support requires reader-side enablement.

What memory protection mechanisms are implemented in I²C and RF modes?

In I²C mode, a single password protects all write operations (I2C_Write_Lock bit area). In RF mode, sector-level security allows up to eight independent 32-bit blocks to be individually locked with unique passwords. Both schemes are enforced in hardware and survive power cycles, as defined in Sections 4.1–4.2 and Tables 9–10 of the datasheet.
