The Cortex-A32 is a 32-bit processor built on the ARMv8-A architecture, and the company claims that it's 25% more efficient than the Cortex-A7, the firm's current leader in terms of the embedded 32-bit core.

Not only could the new Cortex-A32 could well usher in more efficient and perhaps even smaller boards for enthusiasts who love to tinker but also the power requirement could put it in the front row of the much hyped Internet of things revolution. In its smallest configuration with a 100MHz single-core version it uses less than 4mW, and takes up less than 0.25 mm2 of silicon. ARM claims its Cortex-A32 is highly scalable and can be used in single-core or up to quad-core configurations.

In short it is a more compact Cortex-A35 without the 64-bit support. James McNiven, general manager, CPU group at ARM, told Ars Technica:

"The Cortex-A32 processor, enabled with secure ARM TrustZone technology, builds on the trail blazed by the Cortex-A5 and Cortex-A7 processors in embedded applications such as single-board computing, IoT edge nodes and wearables. "It brings greater performance, efficiency and other benefits of the ARMv8-A architecture for ARM's silicon partners to innovate on for richer, more secure embedded systems."
