Radiation hardening memory is the process of making electronic components and circuits resistant to damage or malfunction caused by high amounts of ionising radiation notably for situations in outer space near nuclear reactors and particle accelerators,or during nuclear accidents or nuclear warfare.
Radiation damage can be caused to the majority of semiconductor electronic components, and radiation-hardened components are based on their non-hardened equivalents with some design and manufacturing changes that lessen radiation damage susceptibility.
The technology of radiation-hardened chips tends to lag behind the most recent advancements because radiation-tolerant microelectronic chip designs require lengthy research and testing. Products that have been radiation-hardened are often assessed for one or more consequent impacts, such as single event effects, improved low dose rate effects, and total ionising dose.High ionising radiation environments present unique design difficulties.
Thousands of electrons can be knocked loose by a single charged particle, leading to electronic noise and signal spikes. This may result in erroneous or unclear results when used to digital circuitry.
This is a particularly critical issue when it comes to the design of nuclear power plants, nuclear weapons, future quantum computers, military aircraft, satellites, and spacecraft. Manufacturers of integrated circuits and sensors destined for the military or aerospace sectors use a variety of radiation hardening techniques to assure the proper operation of such devices. Systems that have been rad(iation)-hardened, rad-hardened, or hardened are the results.
The Global Radiation-hardened memory module Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Microchip launched the Innovative spacecraft system technology is needed to provide connectivity and processing of Radiation-hardened memory for deep space endeavours such as planetary exploration, orbiter missions, and space research.
COTS technologies and scalable solutions are being employed more and more in space applications to give system designers better integration and higher performance while lowering development costs and time to market. Using radiation-hardened Arm Cortex-M7 SoC technology, Microchip Technology Inc.
today announced the qualification of its SAMRH71 Arm-based microprocessor and the availability of the SAMRH707 microcontroller. The SAMRH71 and SAMRH707 devices from Microchip were created with the assistance of the European Space Agency and the French space agency, Centre National D’Etudes Spatiales, in order to further programme and research efforts.
The SAMRH71, a radiation-hardened derivative of Microchip’s COTS automotive SoC technology, delivers a combination of space connectivity interfaces coupled with high-performance architecture with more than 200 Dhrystone MIPS. The SAMRH71’s Arm Cortex-M7 core is connected to high-bandwidth communication interfaces like SpaceWire, MIL-STD-1553, CAN FD, and Ethernet with IEEE 1588 Generalized Precision Time Protocol capabilities.
It is designed for high-level radiation performance, extreme temperatures, and high reliability. The device complies with MIL standard Class V and Q high-reliability grades and is completely ESCC accredited with assistance from CNES. This enables systems to meet stringent compliance criteria.
