Renesas Electronics Company, a premier provider of superior semiconductor options, has launched the RA6W1 dual-band Wi-Fi 6 wi-fi microcontroller (MCU), together with the RA6W2 MCU that integrates each Wi-Fi 6 and Bluetooth Low Power (LE) applied sciences. These connectivity gadgets handle the rising demand for always-connected, ultra-low-power IoT gadgets throughout good residence, industrial, medical and client functions. Renesas additionally launched totally built-in modules that speed up growth with built-in antennas, wi-fi protocol stacks and pre-validated RF connectivity.
Extremely low energy operation for always-connected IoT
Right now’s IoT gadgets should keep at all times related to enhance utility usability and response time, whereas sustaining the bottom attainable energy consumption to increase battery life or to fulfill eco-friendly rules. Renesas’ Wi-Fi 6 MCUs provide options reminiscent of Goal Wake Time (TWT), which permits prolonged sleep instances with out compromising cloud connectivity and energy consumption. That is important for functions reminiscent of environmental sensors, good locks, thermostats, surveillance cameras and medical screens, the place real-time management, distant diagnostics and over-the-air (OTA) updates are important.
Moreover, each MCU Teams are optimised for ultra-low energy consumption, consuming as little as 200nA to 4µA in sleep mode and underneath 50µA in Supply Visitors Indication Message (DTIM10). With the “sleepy related” Wi-Fi performance, these gadgets keep related with minimal energy draw, assembly the rising necessities of contemporary vitality effectivity requirements.
Scalable RA MCU structure with full software program assist
Constructed on the Arm Cortex-M33 CPU core working at 160 MHz with 704 KB of SRAM, the MCUs allow engineers to develop cost-effective, standalone IoT functions utilizing built-in communication interfaces and analogue peripherals, with out the necessity for an exterior MCU. Clients even have the choice to design with a bunch MCU that may be chosen from Renesas’ broad RA MCU choices and connect the RA6W1 and RA6W2 as connectivity and networking add-ons. Each RA6W1 and RA6W2 are designed to work with Renesas’ Versatile Software program Bundle (FSP) and e² studio built-in growth setting. As the primary Wi-Fi MCUs within the RA portfolio, they provide a scalable platform that helps seamless software program reuse throughout the RA household.
Excessive efficiency dual-band Wi-Fi 6 with 2.4 and 5 GHz connectivity
With assist for each 2.4 and 5 GHz bands, each MCUs ship superior throughput, low latency and lowered energy consumption. The twin-band functionality dynamically selects probably the most appropriate band primarily based on real-time circumstances, guaranteeing a secure and high-speed connection even in environments with many related gadgets. Superior options reminiscent of Orthogonal Frequency Division A number of Entry (OFDMA) and TWT increase efficiency and vitality effectivity, making these options nicely fitted to dense city environments and battery-powered gadgets.
Sturdy safety and matter-certified interoperability
The RA6W1 and RA6W2 gadgets provide superior built-in safety together with AES-256 encryption, safe boot, key storage, TRNG and XiP with on-the-fly decryption to maintain information protected from unauthorised entry. The RA6W1 is RED licensed (Radio Gear Directive), which makes it simpler for builders to future-proof their design. Moreover, the system is Matter prepared and authorized with Matter 1.4, and is suitable throughout good residence platforms. Renesas helps each MCUs and modules via the Renesas Product Longevity Program, providing 15-year assist for MCUs and 10 years for modules.
“We’re providing our clients the flexibleness to design with a standalone Wi-Fi system, a Wi-Fi/Bluetooth LE combo, or totally built-in modules relying on their wants,” mentioned Chandana Pairla, the VP of the connectivity options division at Renesas. “These wi-fi options save energy, simplify system design and decrease BOM price. With hosted or hostless implementation choices, clients can confidently start their wi-fi onboarding journey and seamlessly combine into next-generation related programs.”
Two forms of modules, Wi-Fi 6 (RRQ61001) and Wi-Fi/Bluetooth LE combo (RRQ61051) simplify design by integrating licensed RF elements and wi-fi connectivity stacks that adjust to international community requirements. Supported RF certification requirements embody the U.S. (FCC), Canada (IC), Brazil (ANATEL), Europe (CE/RED), UK (UKCA), Japan (Telec), South Korea (KCC), China (SRRC) and Taiwan (NCC). By integrating connectivity on the system degree, the modules scale back design effort and speed up time to market.
Successful combos
Renesas presents “Superior Low-Energy Wi-fi HMI for Family Home equipment” and “Computerized Pet Door & Monitoring System” that mix the brand new Wi-Fi 6 MCU and Wi-Fi/Bluetooth LE MCU with quite a few suitable gadgets from its portfolio to supply a wide selection of Successful Combos. Successful Combos are technically vetted system architectures from mutually suitable gadgets that work collectively to carry an optimised, low-risk design for sooner time to market. Renesas presents greater than 400 Successful Combos with a variety of merchandise from the Renesas portfolio to allow clients to hurry up the design course of and produce their merchandise to market extra rapidly. They are often discovered at renesas.com/win.
Availability
The RA6W1 MCU is now out there in FCQFN and WLCSP packages, together with the RRQ61001 and RRQ61051 modules. The RA6W2 MCU (BGA bundle) will likely be out there in Q1/2026. The gadgets are supported by the FSP, e² studio, analysis equipment and software program growth equipment (SDK) that embody flash reminiscence, PCB hint antennas, connectors and embedded energy profiler for energy consumption evaluation. Renesas additionally presents complete software program instruments to assist system utility growth, in addition to the Manufacturing Line Software (PLT) for manufacturing testing of wi-fi MCUs.
