The cPCI-690 is a 6U CompactPCI single-board computer built around the PowerPC 750FX processor for embedded systems requiring high availability and flexible deployment in telecommunications, data communications, and industrial control environments. Operating at 700 MHz or higher with a 133 MHz frontside bus and up to 1 GB of high-speed SDRAM, the cPCI-690 delivers computing performance suitable for multiprocessor architectures. The board’s Sentinel universal PCI-to-PCI bridge enables operation as either a system controller or intelligent peripheral card without hardware or software reconfiguration—eliminating design constraints in complex backplane systems.
