The Ultra Temperature format extends the standard industrial-grade maximum temperature. The series, says the company, brings extra features to the table, opens the doors for new industrial applications, and passes multiple strict tests to prove its resilience:

  • For example, self-driving vehicles must deal with heat-generating intensive computing and data processing in closed installation spaces, especially in SAE level 2 vehicles (and above) that use data-intensive self-adjusting cruising and lane departure.
  • Fanless embedded systems with increasingly compact mechanical designs face internal space constraints that are a big headache for cooling.
  • Mission-critical applications must be reliable in environments that are often inhospitable to electronics where temperature issues can hinder the effectiveness of detecting and identifying objects.

The Ultra Temperature series offers 3200MHz/s high speed and is available in SODIMM and ECC SODIMM with 16GB and 32GB capacity. Value-added extras are designed to toughen the DRAM and give maximum resilience in any industry:

  • First, a robust 45mu” gold finger provides a tougher, more reliable connection than the typical 30mu” gold finger found on most industrial-grade DRAM.
  • There’s also side fill technology that protects and strengthens delicate solder joints against thermal and mechanical stress.
  • Anti-sulfuration is an additional protective layer on vulnerable parts, protecting them against silver alloy corrosion caused by sulfur.
  • Finally, there’s a built-in thermal sensor that accurately measures and tracks component temperature.

With the original IC and components that meet AEC-Q200 automotive qualification, Innodisk Ultra Temperature series is verified by third-party testers who perform a whole battery of rigorous tests, including:

  • vibration test (MIL-STD-810G 514.7)
  • thermal shock test (MIL-STD-810G 503.6)
  • drop test (ISTA-1A)
  • bending test (EIAJ-4072)
  • gold finger insert and extract tests (100 cycles)

The Ultra Temperature series is now available for sample distribution.
