Single Board Computer for Space - Board Level Products

The SCS750® single board computer for space is Maxwell's answer to the space industry's need for medium- to high-performance computing.  The SCS750 combines the latest generation of IBM PowerPC® processor with large amounts of volatile and non-volatile storage and a variety of interfaces in an industry standard 6u cPCI form factor.

Any radiation upset (SEU) is transparently corrected.  The user never has to worry about executing a bad instruction or accessing corrupt information.  Software development is simplified by using the industry standard VxWorks operating environment.  The SCS750’s powerful processing capability and high availability make it the ideal choice for data processing or spacecraft control applications.
