Key Features
- Dual-interface NFC Forum Type 4 tag with simultaneous I2C (400 kHz) and 13.56 MHz RF access for seamless host-to-reader data sharing
- 2 Kbit EEPROM organized in 256 x 8-bit pages with RF-field energy harvesting enabling battery-less passive operation
- Configurable write-protection and RF-disable locks via I2C commands, providing hardware security for sensitive configuration data
Applications
The M24SR02 is ideal for IoT asset tracking, smart packaging, and consumer electronics pairing applications where an embedded host microcontroller writes configuration or telemetry data over I2C and an NFC-enabled smartphone reads it contactlessly at 13.56 MHz. Its 1.8 V to 5.5 V wide supply range suits both coin-cell-powered wearables and USB-powered accessories. Logistics labels and medical-device authentication tags benefit from the RF-disable feature that prevents unauthorized readout when the product is in transit.

Frequently Asked Questions
How much data can the M24SR02 store, and how is its memory organized for NFC tag applications?
The M24SR02 contains 2 Kbit (256 bytes) of EEPROM organized as a single NFC Data Exchange Format (NDEF) file, with up to 246 bytes available for user payload after system file overhead, and each byte endures at least 200,000 write cycles at 25°C for reliable field-update applications.
What I2C speed does the M24SR02 support, and can it communicate simultaneously over RF and I2C?
The M24SR02 supports I2C at up to 400 kHz (Fast mode) and uses an RF anti-collision arbitration mechanism so that when a 13.56 MHz NFC reader accesses the tag, the I2C bus is held off via a busy flag, ensuring data integrity across both 1.8 V to 5.5 V supply rail access paths.
Which supply voltage range does the M24SR02 require, and does it operate without a battery when powered by an NFC field?
When accessed by a host MCU via I2C, the M24SR02 requires a VCC supply of 1.8 V to 5.5 V; in RF-only mode it harvests energy from the 13.56 MHz field and operates without any VCC connection, enabling completely battery-less passive NFC tag deployments in packaging and asset-tracking labels.
For a compact wearable design, how much board space does the M24SR02 SO8 package require?
The SO8 package measures approximately 4.9 mm x 3.9 mm with a 1.27 mm pitch, occupying under 20 mm² of PCB area, making it straightforward to integrate alongside a microcontroller and NFC antenna coil on a single-layer flexible substrate for wristband or smart-label wearable products.
When is the M24SR02 preferred over a standalone EEPROM for a Bluetooth accessory pairing workflow?
For accessories that need out-of-box NFC tap-to-pair without firmware running, the M24SR02 pre-stores a 246-byte NDEF URI record readable at 13.56 MHz before Bluetooth is active, eliminating the host MCU wake cycle, reducing pairing latency by several seconds compared to a software-only Bluetooth advertising flow on a coin-cell 3 V supply.
