Renesas RZ/G3S is a 64-bit Arm Cortex-A55/M33 microprocessor with low power consumption and enhanced peripherals

Renesas RZ/G3S 64-bit Arm Cortex-A55 microprocessor (MPU) designed for IoT edge and gateway devices consumes as little as 10µW in standby mode thanks to its Cortex-M33 core(s) and features a PCIe interface for high-speed data transfers with 5G wireless modules.

A single-core ARM Cortex-A55 CPU powers the RZ/G3s and can distribute workloads to two sub-CPUs, boosting efficiency in task handling and resulting in fewer components and a smaller system size. The Cortex-A55 core operates at 1.1GHz and is designed to improve power efficiency and performance over its predecessor, the Cortex-A53.

The RZ/G3S isn’t Renasas’ first Cortex-A55 product as they have previously released the RZ/A3UL and the RZ/G2L, both powered by the same Cortex-A55 CPU. Additionally, Renesas launched the 64-bit RISC-V RZ/Five processor late last year. The RZ/G3S boasts high-speed interfaces such as PCIe and GbE, a better standby mode, and improved security features which make it suitable for IoT applications such as tracking devices, home gateways, and smart meters.
