Learn how Teledyne e2v characterizes its Space edge processing components against radiations:

Case study of a 4x Arm® Cortex® A72 + 4GB DDR4 computing module

Radiation effects in Space are of the utmost importance to consider because they can cause damage to electronic components and systems, leading to potential failures or malfunctions. High-energy particles, such as heavy-ions and protons, can cause Single Event Effects (SEE) in electronic devices, which can result in temporary or permanent changes to the device’s performance. Additionally, long-term exposure to radiation can cause degradation in electronic components and systems, leading to reduced reliability and performance over time. Considering radiation effects in the design, testing of space systems is essential to ensure their proper functioning and longevity in the harsh radiation environment of space.

Next generations Space systems are always seeking at higher computing performances to serve modern use cases (Real-time image/video processing, Scientific data analysis, Communications, Autonomous operations, Artificial Intelligence, avionics) with new perimeters in mission profiles (orbits, lifetime in space, satellites redundancy / constellations). Since the high computing performance cannot be served by traditional Radiation Hardened
devices, designers have now to consider more standard computing solutions from the industrial market, not radiation hardened, and ensure at the same time that the system they will build with these solutions can still safely operate under radiations and with an acceptable lifetime.

Teledyne e2v is providing compute intensive Radiation Tolerant digital processing solutions, such as an Arm® Cortex®-A72 processor and a high speed DDR4 memory. QLS1046-Space is a very optimized radiation tolerant module based on these two standalone components.

In the first section of this paper, the strategy adopted by Teledyne e2v to test and fully characterize against radiations its high-speed digital processing solutions is described. Then, the QLS1046-Space product and its Space specific features are presented. Afterwards, the radiation test setups and methods applied on the QLS1046- Space are presented, along with results obtained in heavy-ions, protons, TID, and mitigations.
