FWIW, at least 10 years (maybe at 85°C) is expected of any µP/µC worth its salt outside consumer use. It's just that consumers have accepted somewhat junk-y electronics as a fact of life. (Ok, the improvement cycle is also still quite rapid, meaning a consumer might want to update after 3~5 years anyway.) Considering warranty periods on some goods, you also really don't want to build stuff with lower rated chips—it'l…
I worked on validation at Intel and the primary source of faults over time is electromigration in the lower metal layers and our failure rates went out to 7 years (and there are multiple scenario %-failure curves in that window), and we dialed that back during the war with Athlon. Other sources of error are bit failures in sense amps in low-voltage SRAM circuits. Hitting reliability above 105 C Tj was really really r…
Re: STM32 MCU family goes 64-bit with the STM32MP2x (Cortex-A35)
#51thanks, this is really valuable information. i didn't realize electromigration had gotten so bad
