GR718 is a radiation tolerant 18 port standalone SpaceWire router component that has been developed by Aeroflex Gaisler together with IMEC (BE), in an activity initiated by the European Space Agency under ESTEC contract 4000105402/12/NL/Cbi.No. Out of the 18 SpaceWire ports, 16 use on-chip LVDS transceivers, and two use LVTTL signaling. Included also is the mandatory configuration port, as well as an internal port for system level testing. All ports are capable of operating in 200 Mbit/s. UART and JTAG interfaces, that gives access to the on-chip AMBA AHB bus, are provided for configuration and debugging. SPI and GPIO interfaces are accessible through the configuration port, which allows SPI devices to be accessed and general purpose signaling to be performed through RMAP commands. In addition to the mandatory features in the current ECSS SpaceWire standard, GR718 supports group adaptive routing for path addresses, and packet distribution. It also includes support for the incoming SpaceWire standard revision 1 (ECSS-E-ST-50-12C Rev.1), the SpaceWire-D protocol, and the SpaceWire Plug-and-Play protocol currently being developed for ECSS. The technology used is UMC 180 nm, using the DARE library from IMEC, and the package is a 256 pin CQFP. A development board for evaluation and software development has been manufactured as well.
