Renesas Electronics has announced its RZ/G Series with new 64-bit general-purpose microprocessors (MPUs) for Human Machine Interface (HMI) and IoT edge systems. The RZ/G3L and RZ/G3SE are pin-compatible MPUs that support a broad range of industrial and consumer HMI and IoT gateway and home gateway systems requiring high processing performance and high-speed network connectivity.
Â
The RZ/G3L integrates a GPU (Graphics Processing Unit) for 3D graphics rendering along with an H.264 video codec. This combination is ideal for powering smart retail terminals and medical HMI devices that demand rich graphics and video capabilities. The RZ/G3SE is designed for IoT devices with basic display requirements, such as EV chargers and industrial gateway devices that provide status indicators and configuration screens. Because the RZ/G3L and RZ/G3SE are pin-compatible, developers can reuse a PCB design across multiple product variants, simplifying development and reducing time to market.
Â
The new MPUs deliver high processing performance with a CPU cluster incorporating up to four Arm Cortex-A55 cores running at up to 1.2GHz, together with a Cortex-M33 coprocessor running at 200MHz. At the same time, the third-generation RZ/G Series adopts a proprietary power management architecture that significantly reduces standby power. As a result, the new products can lower standby power to the 1mW level in deep standby mode. They can remain in standby mode while retaining the Linux system in memory and resume operation quickly when needed. These power-saving features are well-suited for industrial and IoT devices that require always-on connectivity.
The RZ/G3L and RZ/G3SE are available now. An evaluation board kit, consisting of a SMARC v2.1 module board and a carrier board, is also available for both devices.
