Aitech's S950 3U cPCI Radiation Tolerant PowerPC® Single Board Computer (SBC) is a powerful rugged cPCI board, specifically designed to operate in the harsh space radiation environment for mission-critical applications such as redundant mission computer, flight guidance and navigation computer, command and data handling computer, solid state recorder, video controller and manipulator controller.
The S950 board is powered by IBM’s 750FX high performance, low power, and Silicon on Insulator (SOI) PowerPC® microprocessor running at 733MHz (upgraded version S950-02 available with 1GHz option). The SOI technology reduces power consumption, and significantly increases processor speed and radiation tolerance. The optional 750GX processor provides additional performance. On-board memory resources are protected from radiation effects utilizing a number of strategies: SDRAM is triple redundant, with a voting mechanism incorporated in a radiation tolerant FPGA. Boot flash integrity is guaranteed by dual redundancy (i.e. two independent banks of boot Flash) in combination with a watchdog mechanism.
Complimentary memory resources consist of 64 MB ECC-protected user flash. The user flash has an optional Flash FileSystem Driver (FFD) software package to implement a file-system for up to 60 MB. Designed to endure in space environment, the S950 design utilizes radiation tolerant devices for implementing all on board resources such as System Controller (PCI bridge and Memory Controller), cPCI Bridge and other critical system functions including reset mechanism, interrupt controller, two serial ports, four timers/counters and watchdog timer.
To expedite the transition from development to deployment, Aitech provides 100% software compatible development boards and a 10/100BaseT Ethernet interface is provided for software development only. Designed to withstand the rigors of space environments, the S950 ’s highly integrated design guarantees the highest performance and versatility available on any rugged conduction cooled cPCI PowerPC® SBC.
