RZ/A3UL Block Diagram
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.
