The switching characteristic of the military-temperature grade Intel® Arria® 10 devices is the same as the devices with -I3 FPGA fabric speed grade and transceiver speed grade 4 as indicated in the Intel® Arria® 10 Device Datasheet, with exceptions described below:

• Supported temperature range:
  • Ambient and junction temperature of –55°C during device power-up and configuration.
  • Ambient temperature of –55⁰C for device functionality support and complies with Intel® Arria® 10 performance specifications using timing model corresponding to temperature junction range from –40°C to 125°C.
• Transceiver capable of driving backplane up to 13 decibels (dB) only.
• DDR4 maximum performance at 800 MHz.
• For military grade devices, the VCCLSENSE and GNDSENSE to the voltage regulators must be connected and used.
• On-chip termination (OCT) calibration resistance tolerances:

  OCT	IO Standard	Tolerances (%)
  RT	POD12	±20
  	SSTL and HSTL	-15 to 40
  RS	All supported I/O standard	±20

  Note: To understand the impact of termination impedance variation, Intel® recommends that you perform signal integrity simulation using the IBIS or HSPICE models.

The military-temperature grade Intel® Arria® 10 devices support the following serial interface IPs:

• PCI Express* ( PCIe* ) IP Gen1 and Gen2 x1, x2, x4, and x8 modes. Gen3 x1 and x2 modes only.
• Triple-Speed Ethernet IP in GXB mode.
• Low Latency Ethernet 10G MAC IP in 10G mode.

For more information about Ethernet IP or other IP-related support, submit a Service Request at the My Intel support page.

Prototyping industrial temperature grade devices may be substituted for military temperature range devices due to the shorter lead time.

Use the following guidelines to compile your design using the Intel® Quartus® Prime Pro Edition software for industrial or military devices:

• When using military models with military devices, select an applicable military speed grade 3 (M3) part code and compile or recompile your design.
• When using military models with industrial devices, select an applicable industrial speed grade 3 (I3) part code and update the Operating Settings and Conditions dialog box to reflect –55°C (Minimum) and 125°C (Maximum) temperatures before compiling or recompiling your design.
