The A53 is very popular in automotive and embedded applications. I'm familiar with the iMX8 and the S32G but I'm sure there are others.

- adrian_b 3y agoIt is very popular only because almost all companies that are neither Chinese nor smartphone-oriented have failed to introduce any products with less obsolete ARM cores, for many, many years. NXP has begun to introduce products with Cortex-A55 only recently, but they should always be preferred for any new designs over the legacy products with Cortex-A53, because the Armv8.2-A ISA implemented by Cortex-A55 corrects some serious mistakes of the Cortex-A53 ISA, e.g. the lack of atomic read-modify-write memory accesses. The people who still choose Cortex-A53 for any new projects are typically clueless about the software implications of their choice. Unfortunately, there are only 3 companies that offer CPUs for automotive and embedded applications with non-obsolete ARM cores: NVIDIA, Qualcomm and MediaTek. All 3 demand an arm and a leg for their CPUs, so whenever the performance of a Cortex-A55 is not enough it is much cheaper to use Intel Atom CPUs than to use more recent ARM cores, e.g. Cortex-A78.
