The RZ/G3L is a general-purpose microprocessor (MPU) designed for HMI devices, integrating a quad-core CPU, microcontroller core, 3D graphics accelerator, video codec, PCIe interface, and TSN-enabled Gigabit Ethernet on a single chip. With low-power standby capability and advanced security functions, the RZ/G3L reduces system power consumption and improves reliability for HMI devices and edge computing applications. Full pin compatibility between the RZ/G3L and RZ/G3SE MPUs allows 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.
