Simplifying Radio Connectivity

Low-power, low-voltage solutions for WPAN and LPWAN wireless applications

Arm Cordio is Arm’s family of standards-based low-power wireless IP. It offers a complete solution for LPWAN (Low-Power Wide-Area Network) applications based on the NarrowBand IoT (NB-IoT) standard, and complete RF-to-Application coverage for WPAN (Wireless Personal Area Networks) radios based on the Bluetooth 5 and 802.15.4 standard.

WPAN – Bluetooth 5 and 802.15.4

Arm Cordio IP provides on-chip radio connectivity for SoCs implementing WPAN wireless solutions for IoT. Cordio radio cores are fully integrated solutions with a hardware core and software stacks, and profiles. These low-voltage, low-power cores are designed for optimal efficiency with the Arm Cortex-M processor family.

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

Complete Radio IP

The Cordio radio IP series includes highly integrated and ultra-low power CMOS radio IP cores along with link layer firmware. 

It supports Bluetooth 5 and 802.15.4, individually or in combined configuration, and is targeted towards select process nodes.

Standards RTL

The Cordio IP is available as RTL (Register Transfer Language) delivery, optimized for low-power with support for Bluetooth low energy and 802.15.4 standards, to be used with Arm Cordio radio front end or with a 3rd party radio front end.

It is ideal for designers who want to implement the latest features with a qualified/certified solution for reduced risk and reduced time to market.


The Cordio software series consists of Bluetooth link, stack, and profiles. 

The software can be optimally combined by silicon manufacturers to create a complete "link layer-to-application" software solution to accelerate time to market.
