Moore’s law of ever-increasing miniaturization seemingly never reached
the automotive industry. Dozens of chips found in everything from
electronic brake systems to airbag control units tend to rely on
obsolete technology often well over a decade old. These employ
comparatively simple transistors that can be anywhere from 45 nanometers
to as much as 90 nanometers in size, far too large—and too primitive—to
be suitable for today’s smartphones.
When the pandemic hit, replacement demand for big-ticket items like new
cars was pushed back while sales of all kinds of home devices soared.
When the car market roared back months later, chipmakers had already
reallocated their capacity.
Now these processors are in short supply, and chipmakers are telling car
companies to wake up and finally join the 2010s.
