Teledyne e2v’s Radiation Tolerant Quad ARM® Cortex®-A72 Space Processor Successfully Passes 100krad TID Testing

GRENOBLE, FRANCE - Media OutReach - 16 November 2020 - Teledynee2v has announced that its popular LS1046-Space processor has now passedstringent total ionizing dose (TID) radiation tests, achieving 100kradresilience. This multi-core device, which features four64-bit Arm® Cortex®-A72 processing cores, was able to operate as normalafter the TID tests had been undertaken. Theseresults complement those previously obtained in terms of single event latch-up(SEL) and single event upset (SEU) when exposed to heavy-ions up to more than60MeV.cm²/mg.


Running at operating frequenciesof up to 1.8GHz, Teledyne e2v LS1046-Space is based onNXP processor technology. It has a built-in 64-bit DDR4 SDRAM memory controller with 8-bit error correctedcode (ECC), plus a 2MByte L2 cache sharedacross its cores. L1 and L2 caches are both ECC-protected, so asto offer a high degree of immunity to data corruption. This high-reliabilityprocessor is supplied in a 780-ball BGA package and comes with a wide range ofinterfaces embedded - including 10Gbit Ethernet,PCI-Express (PCIe) 3.0, SPI, I2C, multiple UARTs, etc.Conforming with NASA Level 1requirements, and typically integrated into space-oriented single board computers(SBCs), it is commonly used in satellite-based imaging related tasks, such asprocessing/conditioning and image data compression, as well ultra-low latencycommunications and on-board decision making (leveraging AI algorithms).


Thanks to the new test resultsobtained, customers will now have the informationneeded to know how the processing cores incorporated into LS1046-Space devicewill behave within challenging space settings. Engineers will be able to makebetter-informed choices about device selection by referring to the detailed testdata now available. The TID figures will give them strong assurances about the longevityof these units when deployed into space, while the SEL/SEU heavyions results provide elevated confidence in ongoing functional integrity.


"As a company, we have been involved in space projects for overthree decades, working with the leading agencies and commercial entities inthis sector. Our customers are fully aware of the reputation our processor ICshave gained, as well as the performance and extreme reliability benefits that canbe brought to their hardware implementations through using them," states ThomasGUILLEMAIN, Marketing & Business Development Manager at Teledyne e2v."These latest radiation results give a strong validation of the value that our radiation-tolerant,compute-intensive processors offer to space applications, with unquestionable reassurancethat they can survive in the most extreme operating conditions."


"Wehave set out a well-defined road map to follow on from this, with fullcharacterization of the accompanying peripheral interfaces by early 2021, thencomprehensive single event functional interrupt mitigation testing by themiddle of that year," he concludes.
