Supermicro AOC-IBUTTON68


SKU: AOC-IBUTTON68 Category:




  • Unique, factory-lasered and tested
    64-bit registration number (8-bit family code + 48-bit serial number
    + 8-bit CRC tester) assures absolute traceability because no two
    parts are alike

  • Multidrop controller for 1-Wire

  • Digital identification and
    information by momentary contact

  • Chip-based data carrier compactly
    stores information

  • Data can be accessed while affixed
    to object

  • Button shape is self-aligning with
    cup-shaped probes

  • Stainless steel case engraved with
    registration number withstands harsh environments

  • Easily affixed with self-stick
    adhesive backing, latched by its flange, or locked with a ring
    pressed onto its rim

  • Presence detector acknowledges
    when reader first applies voltage



  • 1128 bits of 5V EEPROM memory
    partitioned into four pages of 256 bits, a 64-bit write-only secret
    and up to five general purpose read/write registers

  • Write access requires knowledge of
    the secret and the capability of computing and transmitting a
    160-bit MAC as authorization

  • Secret and data memory can be
    write-protected (all or page 0 only) or put in EPROM-emulation mode
    (“write to 0”, page 1)

  • On-chip 512-bit SHA-1 engine to
    compute 160-bit MAC and to generate secrets

  • Reads and writes over a wide
    voltage range of 2.8V to 5.25V from -40°C to +85°C

  • Communicates to host with a single
    digital signal at 14.1kb per second using 1-Wire protocol

  • On-chip 16-bit CRC generator for
    safeguarding data transfers

  • Overdrive mode boosts
    communication speed to 125kbps

  • Operating temperature range from
    -40°C to +85°C

  • Minimum 10 years of data retention
    at 85°C
