Stratix V Military Temperature Range Support Technical Brief
As part of the Altera® initiative to provide enhanced commercial off-the-shelf (COTS) devices for military
applications, the temperature range for the Stratix® V device family has been extended to enable operation across the
military temperature range (–55°C to 125°C). This extension allows military programs to benefit from the new
technology and economies of scale by using commercially available Stratix V FPGAs. Stratix V FPGAs are extremely
robust and capable of operating across a wide temperature range with excellent reliability.
Military Temperature Support
The switching characteristic for the Stratix V military temperature grade devices are as follows:
–3 speed grade for transceiver specification
–4 speed grade for core and periphery performance
Stratix V military temperature grade device supports the following:
Internal temperature sensing diode (TSD) range from –40°C to 125°C
Selected transceiver configuration:
Gbps Ethernet (Gbe)
Interlaken for SerialLite III—up to 6 Gbps
JESD204 A/B—up to 6.375 Gbps
Serial RapidIO (SRIO)
Military temperature operation requires additional timing margin over industrial temperature operation to
compensate for the potentially increased variation of delay across temperature.
Altera recommends that you to use military temperature grade devices for production. However, you may
substitute industrial temperature grade for military temperature grade devices during the prototyping phase because
of the shorter lead times of the industrial temperature grade devices.
Use the following guidelines to compile your design using industrial or military devices:
When using military models through industrial devices, select an applicable I4 part code and update the
Operating Settings and Conditions dialog box to reflect –55°C (Minimum) and 125°C (Maximum) junction
temperatures before compiling or recompiling your design.
When using military models through military devices, select an applicable M4 part code and compile or
recompile your design.
