Engineering Brief

The EM4325 is a UHF RFID tag IC fully compliant with EPC Class-1 Gen-2 and ISO 18000-6C standards, operating across the global UHF RFID band (860–960 MHz). It features an integrated sensor interface capable of connecting external sensors for temperature, pressure, or other environmental measurements, making it ideal for cold chain and condition-monitoring applications. With 512 bits of user memory, standard Gen2 security (access/kill passwords), and extended operating temperature range, the EM4325 enables sensor-augmented RFID solutions for logistics, healthcare, and food safety applications requiring both identification and real-time data acquisition.

Typical Applications

  • Cold chain temperature monitoring and logistics
  • Asset tracking with sensor data logging
  • Supply chain management with environmental sensing
  • Pharmaceutical and food safety tracking
  • Industrial automation with sensor integration
  • Smart packaging with condition monitoring
