Product details
Overview
M24LR64E-RMC6T/2 from STMicroelectronics is a dual-interface Dynamic NFC/RFID tag IC integrating 64-Kbit EEPROM, ISO 15693 RF interface, I²C bus (400 kHz), energy harvesting analog output (Vout), and RF busy indicator (RF WIP/BUSY). It operates from 1.8 V to 5.5 V and supports –40 °C to +85 °C ambient, enabling batteryless sensing in industrial asset tagging and smart packaging.
For engineers reviewing the M24LR64E-RMC6T/2 datasheet, M24LR64E-RMC6T/2 pinout, M24LR64E-RMC6T/2 application, or M24LR64E-RMC6T/2 equivalent, key selection criteria include dual-interface memory coherency, RF write-in-progress signaling, configurable energy harvesting sink current, ISO 15693 fast-command support (53 kbit/s), and sector-level password protection in both RF and I²C modes.
Technical Context
The M24LR64E-RMC6T/2 implements a true dual-port memory architecture: I²C accesses 8192 bytes linearly, while RF commands operate on 2048 × 32-bit blocks-both mapping to the same physical EEPROM array with atomic cross-interface consistency. Its RF interface complies fully with ISO 15693 and ISO 18000-3 Mode 1, supporting 10%/100% ASK modulation, Manchester load modulation, and dual subcarrier frequencies (423 kHz / 484 kHz) for low/high data rate operation.
Energy harvesting is implemented via an analog Vout pin delivering regulated DC from the RF field, with four programmable sink current ranges (10 µA to 100 µA) enabling precise power budgeting for external sensors or microcontrollers. The RF WIP/BUSY pin provides hardware-level status feedback during RF write operations, eliminating polling overhead in host systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-interface NFC tag IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST25DV64KC-IE6T | Same ST25 family; 64-Kbit EEPROM; adds I²C interrupt (INT) pin and dynamic register for real-time RF event notification. | Requires interrupt-driven host firmware; better suited for high-frequency sensor wake-up than static logging. | Select when RF-initiated host wake-up or real-time event flagging is required-M24LR64E-RMC6T/2 lacks INT pin. |
| NXH3670UK/V1 | NXP HF RFID tag IC with 2-Kbit EEPROM; no I²C interface; integrated temperature sensor and ADC; lower memory density. | Targeted at self-contained sensing (e.g., cold-chain monitoring); no wired interface for factory programming. | Select only for pure RF-only, sensor-integrated use cases-no dual-interface capability or I²C configurability. |
Compared with ST25DV64KC-IE6T, M24LR64E-RMC6T/2 offers simpler interrupt-free integration but lacks dynamic register access; versus NXH3670UK/V1, it provides full dual-interface control and higher memory density at the cost of no on-chip sensing.

FAQ
What is the function of the RF WIP/BUSY pin?
The RF WIP/BUSY pin is a user-configurable digital output that asserts low during RF write operations or command execution. It eliminates the need for software polling by providing hardware-level status feedback-critical for deterministic timing in high-throughput reader systems. Configuration is done via the Control Register's RF_WIP_EN bit, and the pin remains functional across all supported packages.
How does energy harvesting work on the M24LR64E-RMC6T/2?
Energy harvesting is implemented through the Vout pin, which delivers regulated DC power derived from the RF carrier field. The device supports four programmable sink current ranges (10 µA, 30 µA, 60 µA, 100 µA) set via the EH_CFG bits in the Configuration Byte. This allows precise matching to external sensor or MCU power requirements without external regulators or LDOs.
Can I²C and RF interfaces access memory simultaneously?
No-simultaneous access is prohibited by hardware arbitration. The M24LR64E-RMC6T/2 implements atomic dual-port memory access: an ongoing I²C operation locks the RF interface, and vice versa. This guarantees data coherency without external software coordination. The RF WIP/BUSY pin reflects this state, and I²C timeout prevents indefinite blocking.
What security mechanisms protect memory in RF mode?
In RF mode, memory is protected by a multi-sector password system: up to eight 32-bit blocks can be individually locked with unique passwords stored in the System Memory Area. Each sector supports Read/Write protection bits, and password presentation is required before unlocking. Additionally, the AFI and DSFID fields provide application-level filtering and data format enforcement per ISO 15693.
