Description

The N24RF16E is a RFID/NFC tag with a 16 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 16 Kb EEPROM array is internally organized as 512 x 32 bits in

RF mode and as 2048 x 8 bits when accessed from the I2C interface.
