Robust and Secure Wi-Fi® Modules and SoCs
Which Wi-Fi Product Type is Right for Your Project?
- MCUs
- Plug-and-Play
- Network Controllers
- Link Controllers
Wi-Fi MCUs Provide Advanced Functionality
MCUs offer the most functionality by combining the capabilities of a microcontroller and a Wi-Fi module into a single integrated circuit. They provide the processing power and control capabilities necessary for managing and executing tasks, while also including Wi-Fi connectivity.
The Wi-Fi MCU chip is responsible for handling tasks such as data processing, storage and interacting with other peripherals, in addition to managing the Wi-Fi connection. It is commonly used in applications where a stand-alone device requires both processing capabilities and wireless connectivity, such as advanced IoT devices.
Wi-Fi Plug-and-Play Modules Are the Easiest Way to Connect to the Cloud
Because they include a built-in network stack, plug-and-play modules function like network controllers with one major difference: plug-and-play Wi-Fi modules allow the device to send simple text (ASCII) commands to any MCU over UART.
As the name implies, plug-and-play devices require little to no wireless expertise or user setup. These easy-to-use modules eliminate the need for complex code, RF design, and antenna optimization and shorten the regulatory certification process. In short, they are the easiest way to add Wi-Fi to your design and create a secure cloud connection.
Wi-Fi Network Controllers Offer a Single-Chip Connectivity Solution
In terms of functionality, network controllers sit in the middle. Unlike MCUs, they do not support data processing or peripherals but do provide a single-chip solution for Wi-Fi connectivity and network management.
Because they handle networking functions like discovery, channel selection, data routing and security, they are a good option for connecting to SAM or PIC® MCU with minimal resource requirements. Network controllers are a good fit for applications where you already have an MCU and want to add Wi-Fi connectivity.
Wi-Fi Link Controllers Allow for Greater Customization
When compared to other Wi-Fi devices, link controllers are the simplest. They send and receive Wi-Fi signals but unlike network controllers, they do not have an on-board network stack. The network control functions are handled by an attached MCU or microprocessor (MPU).
Don’t be fooled by their simplicity—link controllers are often faster and cost less than network controllers and MCUs. They are the easiest and most cost-effective option for adding Wi-Fi to an advanced processor.
Our link controllers support RTOS and Linux® Operating System (OS), making them a good fit for industrial applications that are cost sensitive or require high data transfer speeds.
