Connected embedded equipment often needs the same hardware platform to support both display-equipped control panels and headless IoT edge systems. The RZ/G3L and RZ/G3SE MPUs provide a pin-compatible platform that scales between entry-class human-machine interface (HMI) equipment and mid-class IoT edge applications.
Both MPU families combine application processing for Linux® with a real-time Arm® Cortex®-M33 sub-core. This allows time-critical control functions to remain separate from higher-level software, graphics or connectivity workloads.
The RZ/G3L is optimized for HMI applications in industrial, office, building and home equipment. It supports display-equipped systems that need responsive user interfaces, camera input and video-enabled control functions.
The RZ/G3SE is optimized for IoT edge applications such as smart gateways, fleet trackers, energy equipment and data concentrators. Its architecture supports headless systems that prioritize standby power, connectivity and system cost.
High-speed expansion interfaces help both processors support connected equipment. The platform can connect to wireless modules, external AI accelerators, field-programmable gate arrays (FPGAs), and external memory, supporting flexible system expansion.
Low-power operation is based on separate power domains that shut down unused circuits. DDR self-refresh keeps the Linux image in memory, so applications can resume quickly without a full Linux initialization.
Reliability features support industrial operation over long product lifecycles. Error correction code (ECC) protects on-chip memory and DDR interfaces, reducing the risk of failures caused by memory errors.
Software support includes a Civil Infrastructure Platform (CIP) Linux super long-term support (SLTS) kernel, version 6.12. HMI packages such as Chromium, Flutter, and LVGL help accelerate interface development.
