Power-stingy 64-bit MPU targets IoT edge
The RZ/G3S 64-bit general-purpose microprocessor from Renesas boasts standby power consumption of 10 µW for use in IoT edge and gateway devices. It also provides fast Linux bootup and a PCIe Gen2 interface that enables connectivity with 5G wireless modules.
At the heart of the RZ/G3S is an Arm Cortex-A55 CPU core with a maximum operating frequency of 1.1 GHz. Two Arm Cortex-M33 cores serve as sub-CPUs operating at 250 MHz. MPU workloads can be distributed to the sub-CPUs, allowing the device to efficiently handle tasks, such as receiving data from sensors, controlling system functions, and managing power systems.
The MPU’s power management system reduces power consumption to very low levels by turning off some of the independent power domains. A DDR self-refresh function allows the RZ/G3S to retain DRAM data, while also enabling fast Linux startup. Quick startup permits IoT devices, which frequently operate intermittently, to conserve power and extend battery runtime.
In addition to PCIe, the RZ/G3S furnishes Gigabit Ethernet, CAN, and USB interfaces. Useful for IoT applications, like home gateways, smart meters, and tracking devices, the microprocessor features tamper detection to ensure data security.
The RZ/G3S microprocessor is available now in 14×14-mm and 13×13-mm BGA packages.
