Engineering Brief
The M24SR64-Y is a dual-interface dynamic NFC tag IC featuring 64 Kbit of EEPROM accessible via both 13.56 MHz NFC/RFID (ISO 14443-A Type 4 and ISO 15693) and I2C interfaces simultaneously. The chip supports energy harvesting from the RF field, allowing battery-free operation for contactless applications while maintaining I2C connectivity for host processor integration. It includes configurable memory access rights, password protection, and an RF management feature that enables the host to control wireless access, making it ideal for secure IoT applications requiring both wireless provisioning and wired system integration.
Typical Applications
- Consumer electronics pairing and configuration
- Industrial equipment setup and maintenance logging
- Medical device tracking and authentication
- Smart home appliance configuration
- Product authentication and anti-counterfeiting
- Wireless sensor node data collection
