STMicroelectronics M24LR16E Dynamic NFC/RFID Tag

STMicroelectronics M24LR16E Dynamic NFC/RFID Tag features a dual-interface EEPROM, energy harvesting, I2C bus, and an ISO 15693 RF interface. This device is a contactless memory powered by the received carrier electromagnetic wave. The M24LR16E is organized as 2048 × 8 bits in the I2C mode and 512 × 32 bits in the ISO 15693 and ISO 18000-3 mode 1 RF mode. The M24LR16E also features an energy-harvesting analog output and a user-configurable digital output pin toggling during either RF write-in progress or RF busy mode.

The STMicroelectronics M24LR16E Dynamic NFC/RFID Tag is available in a compact ECOPACK2® package and is RoHS-compliant and Halogen-free.
