Renesas Unveils RX261 and RX260 MCUs for the Future of Smart Devices
In the rapidly evolving world of technology, Renesas Electronics Corporation has once again raised the bar, announcing its latest innovation — the RX261 and RX260 microcontroller (MCU) groups.
These cutting-edge MCUs boast exceptional power efficiency, advanced security features, and the ability to withstand even the harshest environmental conditions, making them ideal for a broad range of applications from home appliances to industrial automation. Whether you’re aiming to design energy-efficient devices or tap into the potential of secure IoT systems, the RX261 and RX260 have got you covered.
Revolutionising Power Efficiency for Smart Devices
At the core of the RX261 and RX260 MCUs is a focus on energy efficiency. In today’s world, where every bit of energy saved counts, Renesas has made an impressive leap with these MCUs. Operating at a low active current of just 69μA/MHz and a mere 1μA in standby mode, the RX261 and RX260 ensure minimal power consumption without compromising performance. This combination of power savings and high-speed operation positions them perfectly for battery-powered devices and applications where intermittent operation is key.
For instance, in home appliances such as smart fridges or automated lighting systems, the ability to reduce power use during periods of inactivity is essential for meeting stringent energy efficiency standards. But it doesn’t stop there. Battery-powered applications like e-bikes or mobile thermal printers can extend their operational lifetimes thanks to the MCUs’ remarkable efficiency, while still benefiting from the high-speed performance these chips provide.
Advanced Capacitive Touch Functions
Incorporating capacitive touch functions into modern appliances has become the norm, especially for devices operating in environments where durability is crucial. Renesas’ RX261 and RX260 MCUs come equipped with third-generation capacitive touch IP (CTSU2SL), which brings not only superior noise immunity but also water resistance. This is a game-changer for appliances like washing machines, smart locks, and outdoor equipment, where wet or dirty hands should not hinder functionality.
The beauty of this technology lies in its energy-conscious design. Even in standby mode, the automatic judgement function allows for touch detection, drastically reducing power consumption. With tools such as the QE for Capacitive Touch tuning tool, designers can easily implement these sensors across a wide range of applications, making these MCUs particularly attractive for developers looking to streamline their design processes.
Unparalleled Security Features
Security is no longer an optional feature; it’s a necessity. As more and more devices connect to the internet, they become potential targets for cyber threats. The RX261 and RX260 MCUs take security seriously with the Renesas Secure IP (RSIP-E11A), featuring AES, ECC, and SHA engines for advanced encryption and data protection. Whether you’re working with wireless-enabled devices such as smart home hubs, or industrial systems that require secure firmware updates, these MCUs provide the tools to protect against data breaches and unauthorised access.
By incorporating robust security protocols, including secure boot and secure firmware updates, these microcontrollers ensure that sensitive information remains safe from prying eyes. This level of protection is especially critical in applications like smart locks or building automation systems, where safeguarding user data and operational integrity is paramount.
Features Packed for Performance
While the RX261 and RX260 shine in their energy efficiency and security capabilities, their robust feature set truly sets them apart from the competition. Based on the RXv3 CPU core, which delivers a staggering 355CoreMark at 64MHz, these MCUs outperform many of their 64MHz counterparts, offering 25% lower active current and 87% lower standby current.
But power efficiency isn’t the only standout feature:
- Memory: Up to 512KB of code flash, 8KB of data flash, and 128KB of SRAM ensures ample storage and high-speed operation.
- Connectivity: With Full Speed USB function controller, high-speed on-chip oscillators, and a CAN FD module, these MCUs offer reliable communication across devices.
- Peripheral Support: UART, I2C, SPI, and 12-bit ADCs provide extensive interfacing options for developers working on diverse applications.
This impressive array of features makes the RX261 and RX260 ideal for a variety of use cases, from home appliances and factory automation to mobile devices and more.
Ease of Integration with Evaluation Kits and Winning Combinations
For developers, one of the major advantages of the RX261 and RX260 MCUs is the ease with which they can be integrated into existing systems. Renesas offers multiple evaluation kits that allow developers to test and refine their designs before taking products to market.
On top of that, Renesas has curated over 400 Winning Combinations — technically vetted system architectures that pair the new MCUs with other compatible devices from Renesas’ vast portfolio. Whether you’re building a robust operational touch panel with CAN FD or a portable thermal printer, these combinations provide optimised, low-risk designs that accelerate time to market.
These Winning Combinations are not only convenient but also a testament to Renesas’ commitment to supporting developers through every stage of the design process. With so many ready-to-use solutions, it’s never been easier to create next-generation products that are both secure and energy-efficient.
A Leader in MCU Innovation
Renesas has long been a pioneer in the microcontroller industry, shipping more than 3.5 billion MCUs annually. About half of these serve the automotive sector, while the rest support industrial IoT applications, data centres, and communications infrastructure. With decades of experience and a reputation for delivering high-quality, efficient solutions, Renesas continues to set the standard in MCU technology.
The RX series of MCUs has established a loyal customer base worldwide, thanks to Renesas’ innovative core technology and commitment to addressing the evolving needs of its customers. As Daryl Khoo, Vice President of Embedded Processing at Renesas, aptly put it: “We have built a great relationship with RX customers around the world based on Renesas MCU core technology and years of innovation, including patented technology.”
Renesas’ dedication to fostering innovation through its RX series is clear, and the new RX261 and RX260 MCUs are no exception. They continue to push the boundaries of what’s possible, ensuring that Renesas remains a trusted partner in the ever-changing tech landscape.
Optimising Tomorrow’s Smart Devices
With the RX261 and RX260 MCUs, Renesas has solidified its role as a leader in the next wave of smart device innovation. From their remarkable energy efficiency to their robust security features, these MCUs are poised to revolutionise the way designers approach everything from home appliances to industrial automation.
As the world continues to demand smarter, more efficient technology, Renesas stands ready to deliver with solutions that make a real difference. The future is bright, and with these new MCUs, it’s also secure, efficient, and ready for anything.
