The Arm Cortex-A5 processor is the smallest application processor in the Cortex-A family of processors
The Cortex-A5 processor offers high performance with a low-power consumption, addressing a variety of feature-rich and Linux-capable embedded and IoT applications.
Arm Flexible Access gives you quick and easy access to this IP, relevant tools and models, and valuable support. You can evaluate and design solutions before committing to production, and only pay when you are ready to manufacture.
The processor’s small physical size means reduced manufacturing costs, reduced system leakage and increased low-cost integration. Compared to the Cortex-A9 processor, the Cortex-A5 achieves more than 50% power efficiency while maintaining around 70-75% of the same performance level, making it ideal for wearable technology.
The Cortex-A5 processor is designed to be a highly configurable processor. The instruction and data cache sizes, for example, can be configured from a 64KB maximum size to as small as 4KB for cost-sensitive applications requiring a small application processor with a Memory Management Unit (MMU).
