BAE Systems has produced a radiation-hardened, single-chip SpaceWire interface that performs the functions of multiple chips at a fraction of the size. This saves cost, space, weight, and power. BAE Systems is the first company to produce a chip that is fully compliant to SpaceWire standards. SpaceWire is a spacecraft communication network coordinated by the European Space Agency and is also used in some NASA spacecraft.
The BAE Systems interface chip is radiation-hardened to 200 krad(Si) total dose, measures less than 1E-9 upsets/bit-day SEU, and is latch-up immune. The chip consists of four SpaceWire ports and two peripheral component interconnect busses. They are connected by a six-port router, a multi-gigabyte memory interface supported by a direct memory access controller, and an embedded microcontroller usable for packet processing or standalone operation—Manassas, Virginia
