Renesas Electronics has expanded its RZ/G Series with new 64-bit general-purpose microprocessors (MPUs) for Human Machine Interface (HMI) and IoT Edge systems.
The RZ/G3L and RZ/G3SE are pin-compatible MPUs that support a broad range of industrial and consumer HMI and IoT gateway and home gateway systems requiring high processing performance and high-speed network connectivity.
The RZ/G3L integrates a GPU (Graphics Processing Unit) for 3D graphics rendering along with an H.264 video codec. This combination is ideal for powering smart retail terminals and medical HMI devices that demand rich graphics and video capabilities. The RZ/G3SE is designed for IoT devices with basic display requirements, such as EV chargers and industrial gateway devices that provide status indicators and configuration screens. Because the RZ/G3L and RZ/G3SE are pin-compatible, developers can reuse a PCB design across multiple product variants, simplifying development and reducing time to market.
High performance with 1mW-level standby power
These new products deliver high processing performance with a CPU cluster incorporating up to four Arm Cortex-A55 cores running at up to 1.2GHz, together with a Cortex-M33 coprocessor running at 200MHz. At the same time, the third-generation RZ/G Series adopts a proprietary power management architecture that significantly reduces standby power. As a result, the new products can lower standby power to the 1mW level in deep standby mode. They can remain in standby mode while retaining the Linux system in memory and resume operation quickly when needed. These power-saving features are well-suited for industrial and IoT devices that require always-on connectivity.
High-speed connectivity for expanded system capabilities
Equipped with high-speed interfaces such as PCIe, TSN-capable Gigabit Ethernet, and USB, the new MPUs allow developers to add application-specific features and connectivity options. PCIe supports connectivity to 5G communication modules, Wi-Fi 6 modules and even external AI accelerators. TSN-capable Gigabit Ethernet enables low-latency and highly reliable communications required in industrial networks, where real-time performance is critical.
“As industrial and IoT devices grow more sophisticated, customers need to balance performance, power consumption, connectivity, and design scalability,” said Hari Pendurty, Vice President of the EP Edge AI and Application Processors Business Division at Renesas. “The RZ/G3L and RZ/G3SE were developed to help customers meet these evolving requirements and scale products more efficiently by leveraging a common hardware platform across different applications.”
A rich ecosystem accelerates development
Renesas offers ten ecosystem solutions, including GUI development environments, operating systems (OS), software and system-on-modules (SoMs). Renesas will continue to expand the ecosystem to provide customers with a broader range of validated software, tools, and hardware solutions.
