- 64 Kbit (8 Kbyte) dual-interface EEPROM combining ISO 15693 RF interface and 400 kHz I2C for contactless and wired access
- 1,000,000 write/erase cycle endurance with 40-year minimum data retention ensures long-term reliability in industrial and consumer applications
- Energy harvesting from RF field powers EEPROM writes without a local battery, enabling passive NFC tag data logging
- 8-pin SOIC package with I2C control byte 1010CDDR supports multiple devices on a single bus for scalable memory expansion
What is M24LR64-RDW6T/2 used for?
The M24LR64-RDW6T/2 is well suited for NFC-enabled asset tracking tags, smart labels, and contactless configuration systems where data must be read and written both wirelessly and via a wired I2C host microcontroller. Its RF energy harvesting capability allows passive RFID tags to store sensor readings or configuration data without an onboard power supply. Industrial equipment, medical device lifecycle tracking, and consumer IoT products benefit from the combination of 64 Kbit capacity, high endurance, and dual-interface access.

Frequently Asked Questions
What memory capacity and interface options does the M24LR64-RDW6T/2 offer for a contactless data logging design?
The M24LR64-RDW6T/2 provides 65,536 bits (8 Kbytes) of EEPROM storage accessible via an ISO 15693 RF interface or a 400 kHz I2C bus. This dual access allows a host MCU to pre-load configuration data over I2C while field personnel read it wirelessly with an NFC reader, eliminating the need to physically connect to the device.
How many write cycles can the M24LR64-RDW6T/2 sustain, and what data retention does it guarantee?
The device is rated for 1,000,000 write/erase cycles per page with a minimum data retention time of 40 years. These figures make it suitable for high-frequency update applications such as asset counters, access logs, and configuration registers in industrial equipment that must survive decades of service without data loss.
Can the M24LR64-RDW6T/2 operate without a battery in a passive NFC tag design?
Yes. The M24LR64-RDW6T/2 harvests energy from the RF field of an ISO 15693-compliant reader, allowing EEPROM writes without a local power supply. This energy harvesting feature operates at the standard 13.56 MHz carrier frequency and supports write operations within the RF power envelope, enabling fully passive NFC tag designs that store up to 8 Kbytes of data.
What package does the M24LR64-RDW6T/2 come in, and how does it fit on a standard PCB?
The M24LR64-RDW6T/2 ships in an 8-pin Small Outline (SOIC) package (JESD-30 code R-PDSO-G8), which is compatible with standard dual-inline PCB footprints and 1.27 mm pitch land patterns. The SOIC body is approximately 5x4 mm, making it easy to place alongside an antenna coil and decoupling capacitors on a compact NFC tag PCB.
