The RZ/G3SE is a microprocessor (MPU) designed for IoT devices, integrating a quad-core CPU, a microcontroller core, a PCIe interface, and TSN-enabled Gigabit Ethernet on a single chip. With low-power standby capability and advanced security functions, the RZ/G3SE reduces system power consumption and improves reliability for IoT devices and edge computing applications. Robust hardware security protects IoT endpoints from cyberattacks. The built-in display interface is ideal for applications requiring display functionality. Full pin compatibility between the RZ/G3SE and RZ/G3L enables users to reuse the same PCB design and efficiently scale development across a wide range of applications, from display-equipped HMI devices to display-less IoT devices.
