Key Takeaways

Renesas launches the RZ/G3L and RZ/G3SE microprocessors for HMI and IoT applications, offering pin compatibility.
New chips feature low 1 mW standby power and fast Linux wakeup, ideal for always-connected devices.
High-speed interfaces including PCIe and TSN-capable Gigabit Ethernet enable flexible system expansions.

Expanded RZ/G Series for High-Performance Applications

Renesas Electronics Corporation has unveiled its latest advancements in the RZ/G Series, introducing two new 64-bit general-purpose microprocessors (MPUs) designed for Human Machine Interface (HMI) and Internet of Things (IoT) edge systems. The RZ/G3L and RZ/G3SE offer pin-compatible designs that cater to a wide array of industrial and consumer applications, including high-performance HMI interfaces for smart retail terminals and medical devices, as well as basic IoT devices like electric vehicle (EV) chargers.

The RZ/G3L MPU comes equipped with a Graphics Processing Unit (GPU) for superior 3D graphics rendering and includes an H.264 video codec, making it particularly suitable for applications that require rich video and visual capabilities. In contrast, the RZ/G3SE is tailored for IoT devices needing essential display capabilities, promoting efficient design and expediting development timelines with its pin compatibility feature across the two models.

Enhanced Power Efficiency and Quick Wakeup

Both MPUs deliver robust processing power featuring a CPU cluster of up to four Arm Cortex-A55 cores, capable of clocking up to 1.2 GHz. A Cortex-M33 coprocessor running at 200 MHz complements this architecture. One of the standout features is the integrated power management system, which significantly reduces standby power consumption to just 1 mW. This low power usage enables devices to remain in a deep standby mode while keeping the Linux operating system in memory, allowing for immediate operational readiness when required.

These advancements are specifically beneficial for industrial and IoT devices that demand consistent connectivity and instant responsiveness, particularly in fields where maintainability and low power consumption are crucial.

High-Speed Connectivity for Diverse Applications

The newly released MPUs are built with high-speed connectivity options, including PCIe, TSN-capable Gigabit Ethernet, and USB interfaces. The PCIe feature supports connections to advanced communication systems such as 5G and Wi-Fi 6, as well as external AI accelerators. The TSN-capable Gigabit Ethernet ensures reliable, low-latency communication vital for industrial applications that require real-time data processing.

As noted by Hari Pendurty, Vice President of the EP Edge AI and Application Processors Business Division at Renesas, these new MPUs were designed with the evolving needs of industrial and IoT applications in mind, allowing for a balance between performance, power efficiency, and scalability in product development.

Comprehensive Ecosystem Support

Renesas emphasizes its commitment to supporting developers by offering an extensive ecosystem of ten solutions, which include GUI development environments, operating systems, and system-on-modules (SoMs). This support helps accelerate development cycles by providing a broader array of validated software, tools, and hardware options, facilitating quicker time-to-market for clients.

Innovative Device Implementations

The RZ/G3L and RZ/G3SE MPUs have been paired with various compatible devices, yielding an impressive lineup of applications such as the Mode3 AC EV Charger Wallbox which utilizes the RZ/G3L, and the AI-Enabled Smart Home Security Hub based on the RZ/G3SE, enhancing security through integrations with cameras, microphones, and sensors and enabling cloud connectivity.

Renesas remains dedicated to advancing technologies that foster a safer, smarter, and more sustainable future. By leveraging these new microprocessors, developers can push forward with innovations in automotive, industrial, infrastructure, and IoT domains—and connect billions of smart devices to enhance daily life.
