Product details

Overview

M24LR64E-RDW6T/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, and RF busy indicator pin. It operates from 1.8 V to 5.5 V, supports 6.6–53 kbit/s RF data rates, and delivers 27.5 pF internal tuning capacitance for antenna matching - deployed in smart packaging, industrial asset tagging, and battery-free sensor nodes.

For engineers reviewing the M24LR64E-RDW6T/2 datasheet, M24LR64E-RDW6T/2 pinout, M24LR64E-RDW6T/2 application, or M24LR64E-RDW6T/2 equivalent, key selection criteria include ISO 15693 compliance, dual I²C/RF memory access, energy harvesting sink current configurability, UID-based authentication, and ECOPACK2® package options (SO8/TSSOP8/UFDFPN8).

Technical Context

The M24LR64E-RDW6T/2 implements a true dual-port architecture: the I²C interface enables host MCU read/write control of EEPROM at up to 400 kHz with byte/page write and automatic address incrementing, while the contactless interface complies fully with ISO 15693 and ISO 18000-3 Mode 1, supporting ASK modulation (10%/100%), Manchester load modulation, and Fast command extensions for 53 kbit/s throughput. Its RF WIP/BUSY pin provides real-time status feedback during RF write operations.

Memory is partitioned into 8192 bytes accessible via I²C and 2048 × 32-bit blocks via RF, with independent security schemes: single password protection in I²C mode and multi-sector password locking in RF mode. The integrated energy harvesting analog output (Vout) supports four configurable sink current ranges, enabling direct power extraction from RF fields for ultra-low-power peripherals.

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
ST25DV64KC-IE6T	Same ST25 family; 64-Kbit EEPROM; adds I²C interrupt pin and enhanced RF security (AES-128); no energy harvesting Vout	Preferred where secure cloud authentication and host interrupt signaling are required, but external power is available	Select when AES encryption and deterministic interrupt-driven host response are mandatory; reject if energy harvesting is essential
NXH3670UK/V1	NXP NTAG I2C plus; 1-Kbyte EEPROM; I²C + ISO 14443A; no RF write capability; no energy harvesting	Targeted at consumer NFC tap-to-connect use cases (e.g., smart posters), not industrial dual-port applications	Choose only for cost-sensitive, low-memory, ISO 14443A-only designs requiring simple NDEF messaging - not a functional replacement

Compared with ST25DV64KC-IE6T, M24LR64E-RDW6T/2 offers native energy harvesting but lacks AES; versus NXH3670UK/V1, it delivers full ISO 15693 bidirectional RF write and 64× more memory - making it uniquely suited for battery-free industrial tagging with host-controlled configuration.

FAQ

What is the maximum RF data rate supported by the M24LR64E-RDW6T/2?

The M24LR64E-RDW6T/2 supports 53 kbit/s using Fast commands (e.g., Fast Read Single Block, Fast Inventory Initiated), which is enabled by ISO 15693 extension protocols. Standard high-data-rate mode operates at 26 kbit/s with Manchester coding and 423/484 kHz subcarriers; low-data-rate mode runs at 6.6 kbit/s. All rates are confirmed in Section 9 and Table 20 of ST's DocID022712 Rev 12.

Can the M24LR64E-RDW6T/2 operate without a battery using only RF energy harvesting?

Yes - the Vout pin delivers harvested DC power from the 13.56 MHz RF field, with four user-configurable sink current ranges (1 mA, 3 mA, 6 mA, 10 mA) set via the Control Register. This enables direct powering of external low-power sensors or logic, eliminating batteries in applications like passive environmental monitors or tool calibration tags.

How does RF and I²C memory addressing differ on this device?

I²C access uses linear byte addressing across 8192 bytes (0x0000–0x1FFF), supporting byte and page writes. RF access organizes memory into 2048 × 32-bit blocks (0x0000–0x07FF), with all read/write commands operating on full 32-bit blocks. Security and password controls are implemented separately per interface - no shared address mapping or automatic synchronization between domains.

Which packages are offered for the M24LR64E-RDW6T/2, and are they pin-compatible?

The M24LR64E-RDW6T/2 is offered in SO8 (MN), TSSOP8 (DW), and UFDFPN8 (MC) ECOPACK2® packages. All share identical pinout, signal definitions, and electrical characteristics per STMicroelectronics documentation (Sections 31.1–31.3, DocID022712 Rev 12). Mechanical dimensions and thermal profiles differ, but PCB footprint design must follow each package's specific land pattern.
