Renesas Expands RZ/G Series with 64-bit MPUs for HMI and IoT Edge Systems — Renesas Electronics Corporation

Event summary

Renesas launched the 64-bit RZ/G3L and RZ/G3SE MPUs for advanced HMI and IoT edge systems on September 10, 2026.
The MPUs feature up to four Arm Cortex-A55 cores running at 1.2 GHz and a Cortex-M33 coprocessor at 200 MHz.
The RZ/G3L includes a GPU and H.264 video codec, while the RZ/G3SE is designed for basic display requirements.
Both MPUs are pin-compatible, allowing developers to reuse PCB designs across multiple product variants.
The new products offer 1 mW-level standby power and high-speed connectivity options like PCIe, TSN-capable Gigabit Ethernet, and USB.

The big picture

Renesas' launch of the RZ/G3L and RZ/G3SE MPUs underscores the growing demand for high-performance, low-power solutions in the industrial IoT and HMI sectors. The pin-compatible design and extensive ecosystem support highlight Renesas' strategic focus on scalability and developer efficiency. As IoT devices become more sophisticated, the ability to balance performance, power consumption, and connectivity will be critical for semiconductor suppliers.
