What are the key features of M24LR64E-RDW6T/2?
- 64 Kbit EEPROM accessible via both ISO 15693 NFC/RFID wireless interface and 400 kHz I2C bus, enabling simultaneous wireless and wired data access
- Energy harvesting capability extracts power from the RF field to supply connected external circuits without a battery during NFC reads
- Dual 8-bit and 32-bit memory width modes with 8-pin SOIC package for flexible data formatting in asset tracking and smart label applications
What is M24LR64E-RDW6T/2 used for?
The M24LR64E-RDW6T/2 is designed for smart labels, NFC-enabled product authentication tags, and asset tracking systems where wireless configuration via a smartphone or NFC reader and wired I2C access from a host microcontroller are both required. Its energy harvesting feature allows it to power small external sensors or indicator circuits from the NFC field, enabling batteryless sensor data logging in pharmaceutical cold-chain monitoring and industrial asset management. The 64 Kbit EEPROM capacity supports storing product lifecycle records, firmware configuration blobs, or sensor history that NFC-equipped mobile devices can read and update in the field.

Frequently Asked Questions
How does the M24LR64E-RDW6T/2 allow both NFC wireless and wired microcontroller access to its memory?
The M24LR64E-RDW6T/2 provides dual-port access to its 64 Kbit EEPROM: the ISO 15693 NFC/RFID interface allows wireless read/write from any compatible reader or NFC-enabled smartphone, while the I2C bus at up to 400 kHz enables a host microcontroller to read and write the same memory. Both interfaces can operate simultaneously, with the IC managing access arbitration internally.
What energy harvesting capability does the M24LR64E-RDW6T/2 provide, and how can it power external circuits?
The M24LR64E-RDW6T/2 can extract energy from the ISO 15693 RF field and output it on a dedicated pin to power small external circuits during NFC communication sessions. This harvested energy — typically in the microwatt to milliwatt range depending on field strength and antenna size — is sufficient to drive low-power sensors or LEDs, enabling batteryless NFC sensor tag designs in pharmaceutical cold-chain or IoT asset tracking applications.
How much EEPROM storage does the M24LR64E-RDW6T/2 offer, and what data can realistically be stored in 64 Kbit?
The M24LR64E-RDW6T/2 integrates 65536 bits (64 Kbit or 8 KB) of EEPROM, accessible as 32-bit words or 8-bit bytes. This capacity is sufficient to store hundreds of timestamped sensor readings, a full product lifecycle event log with 1000+ entries, or an NFC Data Exchange Format (NDEF) record containing URLs, text strings, and binary configuration data for smart label and authentication tag applications.
For a cold-chain pharmaceutical label, what NFC standard does the M24LR64E-RDW6T/2 use and what reader devices are compatible?
The M24LR64E-RDW6T/2 communicates over the ISO 15693 vicinity NFC/RFID standard at 13.56 MHz, which is supported by dedicated ISO 15693 RFID readers, NFC Forum-compliant smartphones (Android 4.1+ and iPhone 7+ with Core NFC), and handheld industrial scanners. The ISO 15693 protocol's longer read range — up to 1 metre in ideal conditions compared to the 4 cm of ISO 14443 — makes it practical for scanning labels on shelves or pallets without precise alignment.
