20-Byte ROM for EUI/MAC Addresses, Serial Numbers and Configuration Data

SerialStore is a low cost read-only memory which may be used to store up to 20 bytes of data. The host processor reads the data via an SPI interface. It is extremely low power, consuming nanoWatts when not in use.

SerialStore provides a secure repository for configuration information, serial numbers, MAC addresses, etc. A MAC/EUI allocation service is available. SerialStore is firmware for the PIC10F200 microcontroller and is available as a firmware download from www.hexwax.com. Individual devices are programmed in-circuit using the TEAclipper programming clip. Applications include:

  • Serial number storage
  • MAC / EUI address storage
  • Random number seeds
  • Configuration data storage
  • Calibration data storage
