Programmable SpaceWire interface with atom switch: Components, short paper

We developed a rewritable field programmable gate array (FPGA) using NanoBridge® that exploits atom switch technology. NanoBridge® is newly developed copper wiring technology with dynamic connection capability. Programmable circuitry with SpaceWire interface is realized without configuration memory cells for storing circuit connection information. It prevents single event effect caused by radiation and provides remarkably low power consumption. The first demonstration of the NanoBridge® FPGA on orbit by JAXA's program is planned in 2018.
