The ARM Cortex-A53 is one of the first two central processing units implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings' Cambridge design centre, along with the Cortex-A57. The Cortex-A53 is a two-wide in-order superscalar processor, capable of dual-issuing some instructions.[1] It was announced October 30, 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.
Overview
- 8-stage pipelined processor with 2-way superscalar, in-order execution pipeline
- DSP and NEON SIMD extensions are mandatory per core
- VFPv4 Floating Point Unit onboard (per core)
- Hardware virtualization support
- TrustZone security extensions
- 64-byte cache lines
- 10-entry L1 TLB, and 512-entry L2 TLB
- 4 KiB conditional branch predictor, 256-entry indirect branch predictor
Utilization
The Cortex-A53 is the most widely used platform for mobile SoCs since 2014 to 2025, making it one of the longest-running ARM platform for mobile devices. It is currently featured in most entry-level and lower mid-range SoCs, while higher-end SoCs used the newer ARM Cortex-A55. The latest SoC still using the Cortex-A53 is the MediaTek Helio G50, which is an entry-level SoC designed for budget smartphones.
The ARM Cortex-A53 processor has been used in the LeMaker HiKey since 2015,[3] the Raspberry Pi 3 since February 2016,[4] and the Raspberry Pi Zero 2 W since October 2021.[5]
The Cortex-A53 is also used in a number of Qualcomm, Samsung, and MediaTek SoCs.[6][7][8] Semi-custom derivatives of the Cortex-A53 have been used in Qualcomm's Kryo 250 and Kryo 260 CPUs.[9][10] The Starlink ground terminals utilize a quad-core Cortex-A53 SoC from STMicroelectronics as a main control unit.[11]
The processor is used in the ODROID-C2[12] and in Roku streaming media players (in the high-end models from 2016 and in all models released between 2017 and 2019). 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). It is also used in some Amazon Echo Show models such as the Echo Show 5, Echo Show 8, and Echo Show 5 (2nd Gen).[13]
The processor is used in Fortinet's Fortigate 81F entry-level firewalls.
Automotive electronic control units utilize A53 cores for vehicle network processing and high-performance real-time computations.[14]
