Mar 2, 2021 · The RAD750 comes in two versions: "rad-tolerant" and "rad-hardened". According to a quote in this question, InSight used the rad-hardened version. BAE (the manufacturer of the RAD750) says very little about how their products are radiation-hardened, but does like to tout that they are hardened.

Mar 5, 2021 · Radiation hardened CPUs like RAD750 are radiation hardened for up to 1000 gray. Cool.But, as CPUs have advanced way ahead their mechanical counterparts in miniaturization and fragility, energy dissipation and costs per kg to orbit have lowered, wouldn't just a simple lead shield start being more economic?.

The RAD750 is a radiation-hardened single board computer manufactured by BAE Systems Electronics, Intelligence & Support. The successor of the RAD6000, the RAD750 is for use in high radiation environments experienced on board satellites and spacecraft. The RAD750 was released in 2001, with the first units launched into space in 2005.

Jul 15, 2022 · The widely-used RAD750 is kinda-sorta like a PowerPC, but compared to a 1998 PowerPC (which was desktop state of the practice 24 years ago, not even state of the art), a RAD750 runs at half the clock speed, has very limited main memory, and has even more limited cache memory. $\endgroup$ –

Feb 17, 2015 · This document shows the features of the CPU contained within the RAD750, and there is a section on the device's reliability: The RAD750 will be packaged in a Ceramic Column Grid Array (CGA) package, constructed by attaching extended columns to the original Ball Grid Array (BGA) 360 pin package employed for the 0.25 micron PowerPC 750.

What makes Insight's RAD750 processor so radiation resistant? (compared to 1998 iMac's PowerPC 750) Gizmodo's A 1990s iMac Processor Powers NASA’s Perseverance Rover references NewScientist and says: However, there’s a major difference between the iMac’s CPU and the one inside the Perseverance ...

The processing power in current exploration rovers like the MER's RAD6000 (20Mhz) and Curiosity's RAD750 (200Mhz) is far below anything you would find in any mobile phone today. As far as I understand this is mainly due to the radiation hardening and possibly temperature ranges.

Sep 10, 2022 · Just stumbled across RAD750s successor, the RAD5500. Are there already spacecraft using this Chip, or are there plans for this chip? Looks pretty new!

$\begingroup$ It seems the Galileo CPU could stand a radiation dose of 1 Mrad while the RAD750 version Juno likely had 0.2 Mrad to 1 Mrad (depending on the version they used) $\endgroup$ – asdfex Commented May 11, 2024 at 14:35
