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. |
