More Wireless Connectivity in More Places


Multi-protocol wireless products provide the flexibility needed to perform in a range of environments while being more adaptable to changes in technologies. These qualities help you build IoT devices that not only meet today’s needs but are also ready for the future.

Wireless development is challenging when working with a single protocol; it becomes even more so when working with multiple. The usual concerns, RF and programming, grow in complexity as you add connectivity technologies.

With an easy-to-use multi-protocol solution that provides seamless connectivity across technologies, you can build products that are successful now and ready for what’s to come. Built on the MPLAB® development ecosystem that powers thousands of microcontrollers (MCUs), our multi-protocol modules and SoCs provide more than just a strong connection. These devices:

  • Support multiple technologies including Bluetooth® Low Energy (LE), Zigbee® and Thread®
  • Include a hardware arbiter for seamless multi-protocol operation
  • Include resources to help you through every stage of development

Is Multi-Protocol Right for Your Project?


Multi-Protocol Products—Multi-Protocol Modules and SoCs

Why Choose a Multi-Protocol Device?

Wireless products are everywhere: homes, businesses and even industrial settings. Because there isn’t a single wireless technology that can “do it all,” these devices are using many different standards, adding complexity to IoT product development.

The issues only grow when you try to get all these different devices using different wireless technologies to work together. That’s why there is growing interest in multi-protocol solutions.

A chip that can handle multiple protocols is a versatile powerhouse, unlocking a world of possibilities. They are a streamlined and economical solution to an increasingly complicated problem.

Multi-protocol modules and SoCs can bridge the gap between these different technologies and device networks creating unity among IoT devices.

Multi-Protocol Wireless Benefits

Wireless modules or SoCs with multi-protocol functionality offer several benefits, including ease of use, cost and performance. Using a multi-protocol device can:

  • Decrease the number of components that are needed in a system, which reduces design difficulty and cost 
  • Result in improved performance because it allows devices to communicate with each other more efficiently 
  • Be used to bridge systems that use different protocols, which simplifies the integration of different systems and devices 

Multi-protocol wireless applications offer the flexibility needed to perform in a range of environments while being adaptable to evolving markets. These capabilities help you build IoT devices that not only meet today’s needs but are ready for the future.
