Radiation-Tolerant Plastic-Package ICs
ISL71xxxM radiation-tolerant plastic-package ICs enable cost effective solutions for short duration low Earth orbit (LEO) mission profiles.
CAN Bus Transceiver
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.

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.
Renesas' rad-tolerant plastic packaging flow leverages the company's more than 50 years of spaceflight experience developing rad hard (>75krad) and rad-tolerant (<75krad) products for extremely harsh environments. The upfront radiation effects characterization and AEC-Q100 automotive-like qualification gives customers the utmost confidence to design Renesas radiation-tolerant plastic parts into cost-sensitive small satellites for LEO mission profiles up to five-years. The ISL71xxxM are also well suited for high altitude (>40km) avionic systems, launch vehicles that are prone to heavy ions, and medical equipment where radiation is a concern.
