Cortex-A5 Processor

The ARM® Cortex®-A5 processor is the smallest application processor from ARM. The Cortex-A5 achieves better performance than the ARM1176JZ-S™ processor, and better power and energy efficiency than the ARM926EJ-S™. The Cortex-A5 fully supports the ARMv7-A instruction set, and is feature compatible with the higher performance Cortex-A9 processor at one third of the area and power. It is the most mature, most configurable, smallest, and lowest power ARMv7-A CPU, and provides a high-value migration path for existing ARM926EJ-S and ARM1176JZ-S designs.

The Cortex-A5 delivers a range of high-end features to power and cost-sensitive applications. These include multiprocessing capability for scalable and energy-efficient performance, an optional Floating-Point Unit (FPU) and ARM NEON™ unit for media and signal processing, and a high-performance memory system including configurable caches and a Memory Management Unit (MMU).

Key Benefits

  • ARM’s smallest application processor with Uniprocessor (UP) and Multiprocessor (MP) licensing options
  • Extremely configurable processor with optional NEON, optional FPU and L1 caches configurable from 4K-64KB
  • Full feature set of Cortex-A9 processor at one third the area and power


The Cortex-A5 is designed for applications that require virtual memory management for high-level operating systems within an extremely low-power, low-area profile, including:  

Digital TVs
DVD and audio
Feature phones
Internet of Things
(IoT) - rich nodes
Mobile payments
Smart meters
