Renesas Electronics Corporation has unveiled the RZ/A3M high-performance microprocessor (MPU) designed to power next-generation human-machine interface (HMI) systems across various industries. As part of the RTOS-based RZ/A series, the RZ/A3M enables real-time operation essential for responsive and smooth graphical user interfaces. This new addition to the family focuses on cost-sensitive HMI systems with enhanced built-in memory and graphics capabilities.
It uses a 64-bit Arm Cortex-A55 core and runs at up to 1 GHz and 128 KB of on-chip SRAM. Additionally, a high-speed 128 MB DDR3L-SDRAM is built into a single System-in-Package to remove the need to design a high-speed signal interface for connecting external memory. It supports huge LCD panels with resolutions up to 1280x800, allowing smooth 30 fps video and animation alongside camera outputs for assorted industries like home appliances, industrial automation, healthcare, and building controls.
The RZ/A3M architecture supports both NAND and NOR flash via QSPI, enabling flexible memory options for code and data storage. The distinctive 244-pin LFBGA package with an optimized pin layout allows for low-cost dual-layer PCB designs, accelerating development and reducing overall system expenses.
Renesas provides a comprehensive development environment with evaluation kits, a Flexible Software Package, and support for GUI frameworks like LVGL and Crank, allowing rapid HMI development. Ready-tested combinations of hardware and software components, called Winning Combinations, have been thoroughly validated by Renesas to ensure they complement one another effectively. Renesas offers more than 400 of them to mitigate risk and hasten time to market. The RZ/A3M offers a harmonious blend of performance and cost-efficiency, meeting diverse HMI system needs.
Two variants of the RZ/A3M are currently listed. The RZ/A3M (part number R9A07G066M04GBG#AC0) is currently available starting at $21.35. For full specifications, documentation, and purchasing options, visit the Renesas website
