Renesas Electronics RZ/A3UL High-Performance CPU allows for reaching the full potential of a real-time operating system (RTOS). The RZ/A3UL integrates the 64-bit Arm® Cortex®-A55 CPU core performance with a maximum operating frequency of 1GHz. The device integrates an Octal-SPI memory interface with a simpler and more compact board design. Support for a DDR3L/DDR4 memory interface for high-speed DRAM is also available.
The RZ/A3UL microprocessor (MPU) is ideal for real-time operating system (RTOS)-based compact systems/ The MPU embeds a 64-bit Arm Cortex-A55 core running at a maximum operating frequency of 1GHz. The RZ/A3UL utilizes the superior real-time performance of RTOS to achieve high performance. The RZ/A3UL can reduce startup time from power-on to system startup in industrial equipment, home appliances, LCDs, and operation panels in office automation equipment, audio equipment, and POS terminals.
The Smart Mobility Architecture (SMARC) module board that makes up the RZ/A3UL evaluation kit (EVK) enables the easy design of complex power supply systems. Discrete components like a DA9062 power management IC, 5P35023 programmable clock generator, AT25QL128A flash memory, and SLG46538 GreenPAK™ are mounted on the board. Combining these components reduces the number of components used in conventional systems. This results in a reduction of the PCB board size, contributing to BOM cost reduction.
The RZ/A3UL has an Octal-SPI memory interface (I/F) that enables a simple and compact board design. In addition to Octal-SPI memory, our product lineup includes a DDR3L/DDR4 memory I/F to enable the connection of high-speed DRAM. Choose the memory interfaces suitable for application requirements, like lower design cost or faster memory performance.
RZ/A3UL is compatible with peripheral functions and packages with the RZ/G2UL powered by a Cortex-A55 core and RZ/Five powered by a RISC-V core. Both provide a Linux-based Human Machine Interface (HMI). Deploy as different products using the same board design, simply by replacing the chip. This allows efficient deployment of multiple models, for example, facilitating migration from RTOS-based products to Linux-based products.
RZ/A3UL supports FreeRTOS and Azure RTOS. A wide variety of middleware is available for RTOS, enabling compact systems with fast RTOS-based startup construction at a low cost. A flexible software package including a HAL driver is provided as a reference for FreeRTOS. TES Guiliani, a commercial GUI tool, is provided and is free of charge for FreeRTOS-based GUI tools, just like other RZ/A series products.
