Renesas RZ/G2L, RZ/G2LC and RZ/G2UL 64-bit MPUs

Renesas has expanded its RZ/G2 general-purpose 64-bit microprocessor (MPU) series, delivering improved AI processing for a wide range of applications. The expanded product line-up includes three 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 series provides scalability from entry-level to high-end design.

The latest MPUs are built around the Cortex-A55 CPU core, which is said to deliver approximately 20% improved processing performance compared with the previous Cortex-A53 core and to provide approximately six times faster essential processing for AI applications. In addition, the MPUs integrate camera input interfaces, a 3D graphics engine and a video codec, providing 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).

The entry-level MPUs feature error checking and correction (ECC) protection for both on-chip memory and external DDR memory. Support for security functions means that users can confidently adopt the MPUs for industrial applications requiring extended service life, making it possible to bring their products to market quickly. For cases where more sophisticated AI functionality may be required, Renesas plans to enhance the functions and performance of the MPUs with its AI accelerator, the DRP-AI.
