ARM Cortex-A53
The ARM Cortex-A53 is one of the first two microarchitectures implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings' Cambridge design centre. The Cortex-A53 is a 2-wide decode superscalar processor, capable of dual-issuing some instructions.[1] It was announced October 30th, 2012[2] and is marketed by ARM as either a stand-alone, more energy-efficient alternative to the more powerful Cortex-A57 microarchitecture, or to be used alongside a more powerful microarchitecture in a big.LITTLE configuration. It is available as an IP core to licensees, like other ARM intellectual property and processor designs.

Utilization
The ARM Cortex-A53 processor has been used in the LeMaker HiKey since 2015[3] and Raspberry Pi 3 since February 2016.[4]
The Cortex-A53 is also used in a number of Qualcomm Snapdragon SoCs.[5][6][7] Semi-custom derivatives of the Cortex-A53 have been used in the Kryo 250 and Kryo 260 CPUs.[8][9]
The processor is used in the ODROID-C2[10] and in Roku streaming media players (in the high-end models from 2016 and in all models released between 2017-2018). Another notable Cortex-A53 application is the Pine A64/A64+ single-board computer.
These cores are used in a 24-core SoC, the Socionext SynQuacer SC2A11.
The processor is used in Amazon Fire tablets, including the Fire HD 8 and the Fire HD 10 (the latter also includes Cortex-A72 cores) as well as the Nintendo Switch.
