Laser diodes characterization can be complex due to the laser’s nature. A good heat dissipation must be provided to avoid lasers being damaged. Unique and challenging equipment is required for a perfect characterization because accuracy is a must with this optical component. The real challenge? The test setup definition and implementation when lasers must be tested in extreme conditions, like vacuum or high/low temperatures.

Microchip’s AVR8 ATmegaS64M1/ATmegaS128 and ARM32 M7 SAMV71Q21 Flight Models (FM) are available in ceramic package with screening equivalent to QML class Q and QML class V quality levels. Engineering samples are available as well. Developing radiation-hardened systems for space applications means long lead times and high cost toward achieving the necessary levels of reliability for multi-year missions in harsh environments.

Displacement Damage is the result of nuclear interactions, typically scattering, which cause lattice defects. Displacement damage degrades minority carrier lifetime; a typical effect would be the degradation of gain and leakage current in bipolar transistors.

Commercial parts will have TID ranges between 3-30 krad(Si)and SEL and SEU ranges between 1-120 MeV. Of course, commercial parts are not designed with radiation performance in mind. Nevertheless, a few commercial ICs have in fact exhibited acceptable radiation hardened characteristics.

Each method has its pros and cons. Which method or combination of methods is best will be hotly debated in the years to come? The case study outlined here demonstrates the significant cost savings that can be realized when answering the question, “How rad hard do I need?” and when considering the use of commercially based parts.
