Renesas Launches 64-bit RZ/G3L and RZ/G3SE MPUs for Advanced HMI and IoT Edge Systems
Renesas Electronics Corporation has expanded its RZ/G Series with the introduction of new 64-bit general-purpose microprocessors (MPUs), the RZ/G3L and RZ/G3SE. These MPUs are specifically designed to address the growing demands of Human Machine Interface (HMI) and IoT edge systems, supporting a wide array of industrial and consumer applications, including IoT and home gateways that require high processing performance and robust network connectivity.
A key differentiator of the RZ/G3L and RZ/G3SE is their pin-compatibility, which allows developers to reuse a common PCB design across multiple product variants. This feature simplifies development and accelerates time to market. The RZ/G3L integrates a GPU for 3D graphics rendering and an H.264 video codec, making it suitable for smart retail terminals and medical HMI devices. In contrast, the RZ/G3SE caters to IoT devices with basic display requirements, such as EV chargers and industrial gateway devices.
These new MPUs are engineered to balance performance, power consumption, connectivity, and design scalability, which are critical considerations for sophisticated industrial and IoT devices. They achieve this through a proprietary power management architecture that enables 1 mW-level standby power, coupled with fast Linux wakeup capabilities for always-connected applications, and high-speed interfaces like PCIe and TSN-capable Gigabit Ethernet for flexible system expansion.
