“Powering Small Satellite Constellations with Plastic ICs” http://www.intersil.com/content/dam/Intersil/whitepapers/rad-hard/powering-s...
Those members, who remember the design, will note that Oscar 40used a CAN bus (common network found in automobiles). The ISL71026M radiation-tolerant 3.3V CAN transceiver provides serial data transmission at speeds up to 1Mbps. Up to 120 transceivers can be connected to a single CAN bus to reduce cabling/harness size, weight and power (SWAP) costs for satellite command and telemetry systems. http://www.intersil.com/en/products/space-and-harsh-environment/harsh-enviro...
The ISL71xxxM family of radiation-tolerant plastic-package ICs is designed to support the emerging field of small satellites that will provide solutions such as high-speed Internet connections to hundreds of millions of users in communities, governments, and businesses worldwide. Fleets of hundreds of small satellites will create mega-constellation networks to deliver broadband Internet links from low Earth orbit (LEO) to every corner of the globe, including rural areas without wireless connectivity access.
