TOKYO, Japan, Sep 11, 2026 – Renesas Electronics has expanded its RZ/G series with the RZ/G3L and RZ/G3SE, two pin-compatible 64-bit microprocessors (MPUs) for human-machine interfaces (HMI) and IoT edge systems. The devices combine Arm Cortex-A55 processing, 1 mW-level deep standby power, PCIe and TSN-capable Gigabit Ethernet for industrial and consumer HMIs, IoT gateways and home gateways.
The RZ/G3L integrates a GPU (Graphics Processing Unit) for 3D graphics rendering and an H.264 video codec. Applications include retail terminals and medical HMI devices that require graphics usage. The RZ/G3SE supports systems with simpler display requirements, including EV chargers and industrial gateways with status indicators and configuration screens. Because the two MPUs are pin-compatible, developers can use the same PCB design across multiple product variants.
Processing and 1 mW-Level Standby Power
The processors support quad-core or dual-core configurations, with Arm Cortex-A55 cores running at up to 1.2 GHz. A Cortex-M33 coprocessor operates at 200 MHz.
Renesas’ third-generation RZ/G power-management architecture reduces consumption to the 1 mW level in standby mode. The MPUs can retain the Linux system in memory during standby and resume operation when required.
PCIe, TSN Ethernet and USB Connectivity
Connectivity includes PCIe, TSN-capable Gigabit Ethernet and USB. PCIe can connect 5G communication modules, Wi-Fi 6 modules and external AI accelerators. The Ethernet interface supports low-latency and reliable communications for industrial networks.
“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.”
Software and Hardware Support
Renesas offers 10 ecosystem options spanning GUI development, operating systems (OS), software and system-on-modules (SoMs).
- GUI development solutions: LVGL, Embedded Wizard, Slint, Candera, Spyrosoft, Qt Group
- OS solutions: Zephyr RTOS, Atmark Techno
- SoM solutions: Embedded Artists, a Virtium Company, Advanet
Additional RZ/G3L and RZ/G3SE specifications include:
- Quad-core or dual-core main CPU configurations
- 14 mm square, 400-pin LFBGA and 17 mm square, 368-pin LFBGA packages
- Error checking and correction (ECC) on both on-chip memory and the external DDR interface
- Renesas Secure IP, Secure Boot, Arm TrustZone and tamper detection
- Operating temperatures from –40°C to +125°C
- A Verified Linux Package (VLP) compliant with the Civil Infrastructure Platform for long-term support
Reference Designs for EV Charging and Home Security
Renesas has combined the MPUs with other devices from its portfolio in reference designs. The Mode3 AC EV Charger Wallbox uses the RZ/G3L with high-level PLC communication.
The AI-Enabled Smart Home Security Hub uses the RZ/G3SE with cameras, microphones and sensors, along with cloud connectivity.
