Overview
Description
The RZ/A3UL allows customers to achieve the full potential of a real-time operating system (RTOS) while leveraging the performance boost provided by the 64-bit Arm® Cortex®-A55 CPU core with a maximum operating frequency of 1 GHz. It integrates an Octal-SPI memory interface that facilitates simpler and more compact board designs. In addition, it includes versions that support a DDR3L/DDR4 memory interface to enable connection of high-speed DRAM.
Using an RTOS allows systems to start up instantly, in less than a second after boot-up. This feature is ideal for systems that require a fast response time such as industrial equipment, home appliances and office automation equipment with liquid crystal displays or control panels, as well as audio equipment and POS terminals.

OS support of RZ/A3UL
Yes. Renesas provides a flexible software package (FSP) to enable you to freely select an RTOS. This allows you to use the RZ/A3UL with your preferred RTOS as necessary. However, some of the middleware stack is dependent on the FreeRTOS currently, so we plan to integrate the RTOS ...
