New Wi-Fi 6 MCUs to Enhance IoT Connectivity

Renesas Electronics Corporation has launched the RA6W1 and RA6W2 dual-band Wi-Fi 6 microcontrollers, designed to meet the rising demand for always-connected IoT devices across various sectors, including smart homes and healthcare. These MCUs support both Wi-Fi 6 and Bluetooth Low Energy (LE) technologies, ensuring that devices are both efficient and consistently connected.

The expansion into ultra-low power usage is particularly noteworthy. The RA6W1 and RA6W2 boast features such as Target Wake Time (TWT), which allows devices to remain connected while consuming minimal power, essential for applications like environmental sensors and medical monitoring. These MCUs consume just 200nA to 4µA in sleep mode, and under 50µA during Delivery Traffic Indication Message (DTIM10) operation, aligning with modern energy efficiency standards.

Built on the Arm Cortex-M33 CPU core running at 160 MHz with 704 KB of SRAM, these devices support cost-effective standalone IoT applications. They offer integrated communication interfaces and analogue peripherals, thus eliminating the need for an external MCU. Alternatively, they can serve as connectivity add-ons for existing host MCUs from Renesas’s extensive RA portfolio. Both RA6W1 and RA6W2 are compatible with Renesas’ Flexible Software Package (FSP) and the e² studio integrated development environment, promoting seamless software reuse across the RA family.

The MCUs feature dual-band capabilities supporting 2.4 and 5 GHz frequencies. This ensures superior throughput and low latency, automatically selecting the best band for optimal performance in crowded environments. Advanced functions such as Orthogonal Frequency Division Multiple Access (OFDMA) enhance energy efficiency, making them particularly suitable for battery-operated devices.

Security is a primary concern in connected devices. The RA6W1 and RA6W2 incorporate advanced security features, including AES-256 encryption and secure boot mechanisms to safeguard data integrity. Additionally, the RA6W1 is RED certified for compliance with the Radio Equipment Directive, while both MCUs are Matter ready, ensuring interoperability across smart home platforms.

Renesas aims to provide flexibility for customers, allowing them to choose standalone Wi-Fi devices, Wi-Fi/Bluetooth LE combinations, or fully integrated modules. These solutions not only enhance power efficiency but also simplify design processes and reduce costs. The modules are available in configurations that integrate certified RF components and comply with various global certification standards, including those in the U.S., Europe, Japan, and more.

In terms of practical applications, Renesas has developed several “Winning Combinations,” such as advanced wireless HMI for household appliances and pet tracking systems. These combinations leverage the new MCUs alongside other compatible devices, facilitating quicker design-to-market timelines. Over 400 of these pre-validated combinations are available to clients.

The RA6W1 MCU is currently available in FCQFN and WLCSP packages, along with the Wi-Fi 6 (RRQ61001) and Wi-Fi/Bluetooth LE combo (RRQ61051) modules. The RA6W2 MCU will be released in BGA package in Q1 2026. Renesas provides extensive support through the FSP, e² studio, and various development kits that include necessary components for rapid application development and production testing.
