Introduction

The N24RF04 is a RFID/NFC tag with a 4 Kb EEPROM device, offering both contactless and contact interface. In addition to the ISO/IEC 15693 radio frequency identification (RFID) interface protocol, the device features an I²C interface to communicate with a microcontroller. The I²C contact interface requires an external power supply. The 4 Kb EEPROM array is internally organized as 128x32 bits in RF mode and as 512x8 bits when accessed from the I²C interface.
