Most of those chips would be standard commodity silicon components (think op-amps and such) as opposed to purpose-built automotive micro controllers.

- jfim 5y agoAre they really? I was under the impression that automotive grade components were at least certified to a wider temperature range than typical other components. JEDEC 94A annex A mentions that the operational temperature range is between -40C to 150C for automotive grade components.
- bsder 5y agoYou are correct. Automotive parts are also often certified to higher electrical stress levels as well. This is one of the downstream problems of the shortage: even if you produce the chips, you may not have enough test equipment to qualify and certify them in a timely fashion.
- tsomctl 5y agoUh, no. There's a ton of dedicated integrated circuits that are highly optimized for one specific task, and which contain everything you need. For example, an ABS module is going to contain something like the L9396, which does signal conditioning for wheel speed sensors, and mosfet drivers for the solenoids. All in one little package configurable by SPI. And even the standard commodity silicon components are going to be AEC-whatever certified, as others have mentioned.
