The VPX6-187 VPX Single Board Computer is based on the NXP (formerly Freescale) Power Architecture QorIQ P4040/4080 SOC multi-core processor. Available in versions with 4 or 8 Power Architecture cores running up to 1.5 GHz, and up to 8 GB of high-bandwidth DDR3 SRAM, the VPX6-187 Single Board Computer provides high-performance processing and a long list of features and I/O interfaces to satisfy the most demanding requirements of embedded computing. The VPX6-187 Single Board Computer features a large number of I/O interfaces including EIA-232, EIA-422/485 serial, USB, Ethernet, MIL-STD-1553, SATA, TTL and differential and discrete I/O. It is equipped with two mezzanine sites. One mezzanine is capable of supporting a IEEE 1386 PMC or VITA 42.3 XMC module with 64-bits of Pn4 I/O and 12-pairs of differential Pn6 I/O from that site to the backplane connectors as per VITA 46.9. The second mezzanine is designed to support only an XMC with maximum I/O providing 20 differential pairs and 38 single-end signals routed as per VITA 46.9.
