Would the STM32L073RZ be suitable for low earth orbit operational environment

[MColl.1]

Hi all,

I am considering the STM32L073RZ for a low earth orbit application. Would this MCU be suitable for the following operational environment?

Altitudes of 590 – 630 km.

Temperature environment range is -40°C to +70°C.

Total Ionizing Dose (TID) exposure to 12 krad(Si).

Would this device be susceptible to outgassing in a vacuum environment?

If not suitable then are any alternatives available from ST? I have a strong preference for the ST development environment.

Regards

ST only produces very few rad hard part. No MCU found on the website. Look if Cern/Nase/Esa already did some radiation test, such test are mostly done only by possible users. Another aspect is project impact of your contibution failing. If it is a single experiment, constraints are much lower as if your contribuation is critical for the whole mission.

This is a primarily user-driven forum, with only casual ST presence. You should ask this kind of questions directly, through web support form or through FAE.
