ON Semiconductor


ON Semiconductor has released the N24RF family of NFC EEPROM products, providing a scalable design solution which combines conventional EEPROM functionality with an integrated NFC interface for contactless reading and writing of data.

Like a conventional non-volatile EEPROM device, the N24RF includes a digital I2C interface. The NFC interface provides an additional option for contactless reading and writing via an NFC reader such as a smartphone equipped with an NFC radio. The device can communicate with a reader over a range of up to 1.5m.

The N24RF can power itself from the energy of the reader’s RF field during communication, which enables the implementation of batteryless designs.

The N24RF is available in two package options: a SOIC-8 measuring 4mm x 5mm x 1.75mm, and a TSSOP-8, which is 3.1mm x 4.5mm x 1.2mm.
