S730
Radiation Tolerant SpaceWire PMC

• Designed to operate and host on the S950 Single Board Computer (SBC)
• Three SpaceWire full duplex ports – all three ports are brought out of the front panel in the 100-series engineering model
• All SpaceWire ports are ESA ECSS-E-50-12C compliant
• DMA engine for data transfer to and from the SBC via the local PCI bus
• Each SpaceWire port can be enabled or disabled independently
• Each SpaceWire port can independently receive and transmit packets to the SBC
• Each SpaceWire can be configured with selectable clock frequencies of up to 100 MHz
• Timecode can be responded to or generated by each SpaceWire port
• Rear I/O via the SBC to the cPCI backplane for the conduction-cooled configuration
• 32-bit PCI 2.2 compliant PCI Master/Slave interface at 33.333 MHz
• Nominal power consumption is estimated at less than 5 Watts (for SpaceWire only)
  
• Designed to operate with a minimum TID of over 100 krad (Si) in the flight model
