The Germanwings 9525 deliberate crash in the French Alps in March, 2015 may hold relevant information & datapoints regarding chip survivability. Both trajectories were near-vertical at very high speeds, (between 4 & 7 "fuselage lengths per second").
The Germanwings crash was hardly "near-vertical." Perhaps we can leave the exaggeration to the media.
Descent rate was ~3500 fpm and took about
10 minutes from top of descent to impact. Roughly a 30° glide path, over a ground track of about 60-70 nm.
It
did, of course, hit a steep mountainside, so the impact angle was closer to 70° or so - and
was at high speed.
