The GR718B is a standalone, radiation tolerant, 18x-port SpaceWire router, enhanced with support for 64 interrupts, SpaceWire-D and SpaceWire standard revision 1. A brief overview of the design background of this device is provided herein. The main design features of the GR718B are also described in this paper. A short summary of the screening and qualification flows for space qualification of the GR718B is given herein. GR718B prototypes have already passed functional and electrical verification and the first flight lot of GR718B is now in its final stage of space qualification. The main outcome the Single Event Effects testing of the GR718B are given here and support the choice of radiation hardening features selected for the design of this device.
