Product details
Overview
M24LR16E-RMC6T/2 from STMicroelectronics is a dual-interface Dynamic NFC/RFID tag IC integrating 16-Kbit EEPROM, ISO 15693 RF interface, I²C bus (400 kHz), energy harvesting analog output, and RF busy indicator pin. It operates from 1.8 V to 5.5 V, supports 6.6 kbit/s and 26 kbit/s RF data rates, and delivers 4 configurable sink current ranges for harvested power management. Used in smart packaging, asset tagging, and industrial maintenance logs where battery-free operation and wired/wireless dual access are required.
For engineers reviewing the M24LR16E-RMC6T/2 datasheet, M24LR16E-RMC6T/2 pinout, M24LR16E-RMC6T/2 application, or M24LR16E-RMC6T/2 equivalent, key selection criteria include ISO 15693 compliance, I²C + RF coexistence, energy harvesting capability, UID-based authentication, and dual-password security (RF multi-sector, I²C single).
Technical Context
The M24LR16E-RMC6T/2 implements a true dual-interface architecture: its I²C port enables direct microcontroller read/write at up to 400 kHz, while its contactless interface complies fully with ISO 15693 and ISO 18000-3 Mode 1, supporting both 10% and 100% ASK modulation and Manchester load modulation with 423 kHz/484 kHz subcarriers.
It features on-chip tuning capacitance (27.5 pF), field detection (FIELD_ON bit), and configurable RF WIP/BUSY pin behavior-enabling host systems to synchronize I²C access with ongoing RF transactions and avoid data corruption during concurrent operations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-interface NFC tag applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST25DV16K-IER | Same ST25 family; 16-Kbit EEPROM, ISO 15693, I²C, but adds dynamic registers and NDEF support; no energy harvesting output pin. | Better suited for NFC smartphone interaction (NDEF messaging), less optimal for self-powered sensor nodes. | Select when NDEF compatibility or dynamic register mapping is required over harvested power delivery. |
| NXH3670UK/N1 | NXP part; 2-Kbit EEPROM, ISO 15693, I²C, integrated RF frontend, but lacks energy harvesting sink control and UID uniqueness guarantee. | Lower memory density and no programmable Vout limits use in high-data logging or autonomous sensor scenarios. | Choose only for cost-sensitive, low-memory applications where external energy harvesting circuitry is acceptable. |
Compared with ST25DV16K-IER, M24LR16E-RMC6T/2 provides dedicated energy harvesting control essential for battery-free sensing, while NXH3670UK/N1 trades memory and power management for lower BOM cost and simplified RF matching - making M24LR16E-RMC6T/2 the sole choice for field-powered, high-integrity dual-access tagging.

FAQ
What is the purpose of the RF WIP/BUSY pin?
The RF WIP/BUSY pin signals whether the IC is actively processing an RF command (e.g., block write or inventory). When asserted, it warns the I²C host to defer writes to prevent data corruption during concurrent RF/I²C access. Its behavior is user-configurable via the control register to indicate either "write in progress" or "RF powered and ready."
How does energy harvesting work on this device?
Energy harvesting uses the AC0/AC1 pins to capture RF field energy from an ISO 15693 reader, rectify it internally, and deliver it as a regulated DC voltage on the Vout pin. The sink current is software-selectable across four ranges (10 µA to 1 mA), allowing optimization for powering external sensors, comparators, or low-leakage logic without external regulators.
Can the M24LR16E-RMC6T/2 be used with standard NFC smartphones?
Yes - it fully complies with ISO 15693, which is supported natively by Android devices with NFC and many iOS devices via Core NFC APIs. It supports standard commands (Read Single Block, Write Single Block) and Fast variants, enabling smartphone-based configuration, diagnostics, and data retrieval without proprietary middleware.
What security mechanisms protect data in RF and I²C modes?
In RF mode, security uses per-sector 32-bit passwords (up to 16 sectors), enforced before write or read access. In I²C mode, a single global password protects all writes via the I2C_Write_Lock bit. Both modes support UID-based authentication and DSFID/AFI filtering, and the system memory area includes CRC-protected configuration bytes to prevent tampering.
