Description
GR718B is a radiation tolerant 18 port standalone SpaceWire router component that has been developed by Cobham Gaisler together with imec (BE), in an activity initiated by the European Space Agency under ESTEC contract 4000105402/12/NL/CBi.No. All ports are capable of operating in 200 Mbit/s. UART and JTAG interfaces, that gives access to the on-chip 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, GR718B 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´s CMOS 180 nm, using the DARE library from imec, and the package is a 256 leads CQFP. The GR718B router is expected to withstand 300krad(Si) and is single event latch-up immune for linear energy transfer values above 118 MeVcm2/mg. The GR718B is currently being qualified for space applications following an ESCC9000 lot validation approach. Flight units will be available from January 2017. Prototypes and evaluation boards are already available.
