Newport Thermal Ratings

Gateworks pre-installs a heatsink on the CPU for all Newport boards. This heatsink provides basic cooling for the board during development but customers need to design their own thermal solution based on their particular enclosure, environment and operating conditions.

The Cavium CN80xx Octeon TX CPU is rated at:

  • 800MHz Dual Core (CN8020 - BGA676)
    • Max: 100C Tj (Junction Temp), 95C Tc (Case Temp)
    • Min: -40C Tj (Junction Temp), -40C Tc (Case Temp)
  • 1.5GHz Quad Core (CN8030 - BGA676)
    • Max: 95C Tj (Junction Temp), 90C Tc (Case Temp)
    • Min: -40C Tj (Junction Temp), -40C Tc (Case Temp)

Newport Power Dissipation

The following table provides typical power consumption for the various Newport board models without any attached peripherals.
