Near field communication interface for a packet-based serial data transmission using a dual interface EEPROM

A new application for a wireless packet-based serial data transmission using an EEPROM with an I2C and a NFC interface will be presented in this paper. Our system allows the secure exchange of a large amount of data compared to classical NFC appliances. A protocol handles the fragmentation, encryption, error handling, session handling and authentication. A brief description of the used ST M24SR64-Y EEPROM including the memory layout and the used special hardware features will be discussed. In addition, a new kind of antenna for such an application with respect to a reduced footprint is presented. Our target is an implementation for industrial or medical applications to write a configuration or firmware or to read parameters from the device with no direct electro-mechanical connection.

I. Introduction

Near Field Communication has a growing impact on the everyday life for lots of people. Since the underlying Radio-Frequency Identification (RFID) technology is frequently used for many years and applications, NFC - as a special implementation - is currently applied in mobile payment, authentication and access systems. Thus, this technology has proven to be stable and reliable on consumer electronics.
