Smallest Processor for 32-Bit

The Arm Cortex-A processor series is designed for devices undertaking complex compute tasks, such as hosting a rich operating system platform and supporting multiple software applications. Cortex-A32 is a low-power 32-bit only processor with ultra-high efficiency, suitable for the diverse embedded and IoT markets.

Features and Benefits

Advanced Power Management

Idle power management features introduced in Cortex-A32 reduce leakage power in the CPU idle states, making it suitable for long periods of inactivity. It is the most efficient Arm processor and achieves low dynamic power in CPU active states.

Scalable and Versatile

This processor can be used in different configurations, from a single core to a maximum of four CPU cores in a cluster, providing flexible options for designers and scalability for diverse embedded applications.

New Architectural Features

Armv8-A architecture in Cortex-A32 is compatible with existing Armv7-A 32-bit software and provides enhanced floating performance for media and video applications. It also delivers substantially faster software encryption for increased security.

Use Cases

Where Innovation and Ideas Come to Life

Energy-harvesting wireless sensor nodes use ambient energy as a power source where batteries or cables are not viable. When those nodes also need to support a rich operating system, Cortex-A32 provides the processing power needed, combined with superior energy efficiency and built-in TrustZone security.
