Wi-Fi MCUs

Ultra-Low-Power, Always Connected

We design our Wi-Fi MCUs specifically for IoT-connected devices. Whether battery- or mains-powered, our ultra-low-power Wi-Fi solutions deliver always-on connectivity and fast time-to-market—ideal for IoT devices that require long battery life, high performance, strong security, and easy development. As a hardware and software innovator, we offer products that support diverse operation modes and optimize connected solutions for cost and power.

VirtualZero Always Connected

VirtualZero™ delivers ultra-low power Wi-Fi for always-connected IoT devices—meeting standby regulations for wall-powered devices and extending battery life in portable products without compromising latency and connectivity.

Dual-Band

Our Wi-Fi IoT MCUs support 5GHz in addition to 2.4GHz, enabling greater scalability, lower latency, higher throughput, and reduced average power consumption in crowded wireless environments.

Fast & Easy Development

Accelerate design and integration with our Renesas Flexible Software Package (FSP), development tools, and pre-certified commercial modules. Our EVKs enable easy application development and customized solutions.

Flexible Architecture

Standalone mode allows a user app to run on the Wi-Fi MCU. Attached mode lets the Wi-Fi MCU handle connectivity for another MCU. Memoryless radio-co-processor (RCP) mode operates without onboard memory.

Always Connected IoT

Ensuring IoT devices stay connected to Wi-Fi and the cloud at all times is more essential than ever. Users demand fast, remote access, and near-real-time event notifications. Operators require on-demand status, diagnostics, and remote management. Staying always-connected while minimizing power consumption is vital for battery life and compliance with ecodesign regulations. Our products lead the industry in low-power, always-connected, and sleep modes, making them an ideal choice for designers’ IoT needs.

Wi-Fi 6 for IoT

Wi-Fi 6 (802.11ax) introduces major enhancements to Wi-Fi technology, of which a few are key improvements for IoT. Target wake time (TWT) offers enhanced power-save capabilities, extending sleep duration for always-connected devices, with tighter power-save interoperability between AP and devices. Wi-Fi 6 also reduces latency with OFDMA, scheduled access, TWT, and multi-user access for better QoS.
