The Curtiss-Wright VPX6-1957-A01A1650 is a 6U VPX single board computer built on the Intel Core i7-3612QE quad-core processor, delivering 2.1 GHz per core with 6 MB L3 cache and Intel AVX support. Engineered for aerospace and defense embedded systems, this SBC operates in air-cooled, conduction-cooled, and Air Flow Through configurations. The platform integrates 8 GB or 16 GB DDR3 SDRAM with ECC protection, 32 GB NAND flash storage using SLC technology rated for 20-year data retention at +85°C, and Intel HD Graphics 4000 capable of driving three independent displays. Connectivity spans quad 1 GbE ports, dual 10 GbE backplane links, 16 lanes of PCIe Gen2 configurable as 4×4, 2×8, or 1×16, four SRIO Gen2 ports, two VITA 42 XMC mezzanine sites, five serial channels, and four SATA 2.0 interfaces. Supports Windows WES7, Linux, and VxWorks operating systems.
