New entry-level MPUs enhance scalability of RZ/G2 lineup

The new RZ/G2L MPUs are built around the Cortex-A55 CPU core, which delivers approximately 20% 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.”

“With AI transforming our daily lives, greater on-device compute capabilities are required to provide real-time insights for billions of IoT endpoints,” said Dipti Vachani, Senior Vice President and General Manager, Automotive and IoT Business at Arm. “By incorporating Arm technology in its latest 64-bit MPUs, Renesas is accelerating the adoption of endpoint AI by enabling higher-performance IoT devices capable of processing more intelligence on the device.”

As part of the RZ/G Series, 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 ten years, is available.

This makes it possible to dramatically reduce future maintenance costs. Additionally, support for security functions means that customers can also confidently 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 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.

As part of a series of comprehensive solutions for assisting rapid development called 'Winning Combinations', Renesas also offers power supply circuit reference designs that can be flexibly applied to customers’ specific use cases.

Sample shipments of the new MPUs start today, with mass production scheduled to commence sequentially beginning in August 2021. Beginning today, Renesas is accepting reservations for an evaluation board that will allow customers to get an early start evaluating applications for RZ/G2L Group MPUs. In addition, reference designs (circuit diagrams and board layout data) are available starting today. Renesas is currently developing power management IC (PMIC) products optimized for the RZ/G2L Group, and these are scheduled for release later in 2021.
