Renesas launches RZ/G2 general-purpose 64-bit MPUs

Renesas Electronics has announced the expansion of its range of RZ/G2 general-purpose 64-bit microprocessors (MPUs), delivering improved AI processing for a wide range of applications.

The expanded product lineup includes three new entry-level MPU models built around the latest Arm Cortex-A55 core: The RZ/G2L, RZ/G2LC, and RZ/G2UL. Together with the existing mid- to high-end RZ/G2E, RZ/G2N, RZ/G2M, and RZ/G2H MPUs, the total of seven RZ/G2 MPUs is able to provide scalability from entry-level to high-end design.

The RZ/G2L MPUs are built around the Cortex-A55 CPU core, which delivers approximately 20 percent improved processing performance compared with the previous Cortex-A53 core and provides approximately six times faster in essential processing for AI applications.

In addition, the new MPUs integrate camera input interfaces, a 3D graphics engine, and a video codec, providing cost-efficient support for sophisticated functionality for human-machine interface (HMI) applications, such as multimedia processing, GUI rendering, and AI image processing.

The MPUs also feature the Cortex-M33 core, which makes it possible to perform real-time processing for tasks such as sensor data collection without the need for external microcontrollers (MCUs), reducing the overall system cost.

“The use of 64-bit MPUs for processing AI and graphical HMIs have become widespread, increasing the demand for easy to use, high-performance MPUs,” said Hiroto Nitta, Senior Vice President and Head of SoC Business, IoT and Infrastructure Business Unit at Renesas. “Through the introduction of new entry-level products in RZ/G2, Renesas is accelerating adoption of the Linux OS on high-performance MPUs and can help bring innovation that will deliver better performance and enhanced functionality in HMI devices, while driving down the overall cost.”

The new entry-level RZ/G2L Group features error checking and correction (ECC) protection for both on-chip memory and external DDR memory. In addition, a Verified Linux Package (VLP) featuring a Civil Infrastructure Platform (CIP) Linux, an industrial-grade Linux offering guaranteed support and security maintenance for more than 10 years, is available. This makes it possible to reduce future maintenance costs.

In addition, support for security functions means that customers can also adopt the RZ/G2L Group MPUs for industrial applications requiring high reliability and extended service life, making it possible to bring their products to market more quickly.

For cases where more sophisticated AI functionality may be required, Renesas said that it plans to enhance the functions and performance of the RZ/G2L MPUs with its exclusive AI accelerator, the DRP-AI. Renesas aims to include continued pin compatibility and better software reusability in order to reduce the development burden on customers as they add new product versions to their lineups in the future.
