Microprocessor Radiation Test Results: SAMA5D3

The OSSAT team performed a research and development project to further the understanding of COTS processors, in partnership with the Surrey Space Centre (SSC) at the University of Surrey, UK, with support from Research England’s SPRINT programme.

The OSSAT-SSC project team evaluated the latest available COTS microprocessors and assessed their suitability in terms of performance with a view to testing their resilience to the harsh space radiation environment. Three COTS processors were downselected and subjected to a series of research tests to determine processor performance and space environmental resilience.

Releasing test results for the small satellite community to use

This report gives the results of this research in relation to the third of the three downselected processors: the Atmel/Microchip SAMA5D3.

Download the report on the first processor that we tested, Atmel/Microchip SAMV71; and the second processor, the ST Microelectronics STM32H753.
