Software Solutions for Wireless Connectivity

Arm Cordio is a family of standards-based low-power wireless IP. It offers a complete solution for low-power wide-area network (LPWAN) applications based on the NarrowBand IoT (NB-IoT) standard, and complete RF-to-application coverage for wireless personal area networks (WPAN) radios based on the Bluetooth 5 and 802.15.4 standard. 


The Arm Cordio portfolio consists of complete sub-volt radio IP solutions (hardware sub-system), radio standards delivered as soft IP and software (Link/MAC, stack and profiles). Cordio stack and profiles are also offered as an open-source option through Arm Mbed.

Standards Focused for IoT

With the Arm Cordio family of radio IP, semiconductor companies have access to cutting-edge, sub-volt radio solutions and can effectively keep up with evolving standards and processes in a cost-effective, risk-free manner.

Designed for Optimal Efficiency

Optimized for the Arm Cortex-M processor family, Arm Cordio includes everything from antenna to L3 protocol software and all software layers of the NB-IoT standard, PHY and RF, test and debug tools.

Complete Solutions

The Cordio architecture brings extensive choice and flexibility to SoC designers. It provides foundry/process support, radio standards, and software stacks for easy integration with SoC, as well as expanded support through third parties.
