Overview
Renesas’ portfolio of radiation-hardened (rad-hard) digital products is designed to meet high-reliability needs in space, aerospace, and defense applications. This comprehensive lineup includes rad-hard digital isolators, memory solutions, microprocessors, and peripherals. These Hi-Rel solutions are built to withstand the extreme conditions of space environments. We engineer our rad-hard digital products for optimal performance, durability, and precision—ensuring reliable operation in mission-critical systems and robust protection against radiation-induced failures. With cutting-edge technology and proven reliability, these components support the most demanding applications, from satellite communications to advanced aerospace systems.
Manufacturing & Test Information
Renesas has an unparalleled track record of providing highly reliable, efficient, and accurate space-grade products for a wide range of applications, including satellite communications and space flight systems.
Total ionizing dose (TID) response is a key issue for semiconductors in space applications. We address this by performing radiation lot acceptance testing (RLAT) on all space-grade products. For rad-hard products, we perform low dose rate and/or high dose rate RLAT on a wafer-by-wafer basis. For rad-tolerant products, we perform low dose rate RLAT on a per-wafer-lot basis. We design our space products to handle heavy ion interactions with minimal disruption to operation while mitigating single event effects (SEE)—including single event transients (SET), upsets (SEU), and destructive events like burnout and latch-up (SEB/L).
Our rad-hard hermetic and plastic products follow MIL-PRF-38535/QML qualified production flows and are 100% burned-in to ensure the highest reliability. We use an automotive-like production flow to produce rad-tolerant space plastic products, delivering robust, cost-sensitive solutions for new space applications. By leveraging the latest technology, our QML Class V, QML Class P, QML Class Q, and radiation-tolerant space plastic products are revolutionizing the Hi-Rel and space marketplaces.
