Renesas Unveils Powerful 1GHz RZ/A3UL 64-Bit MPUs with RTOS Support That Enable High-Definition HMI and Quick Startup

Renesas Electronics announced the RZ/A3UL group of microprocessors (MPU) that enables both a high-definition human-machine interface (HMI) and quick startup for applications that require high throughput and real-time capabilities. The new 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. 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.

The new RZ/A3UL MPUs integrates an Octal-SPI memory interface that facilitates simpler and more compact board designs. In addition, the new devices include versions that support a DDR3L/DDR4 memory interface to enable connection of high-speed DRAM. For example, the DDR3L/DDR4 memory interface achieves a data transfer speed that is approximately 10 times faster than the Octal-SPI memory interface, maximizing the performance needed to enable an HD (1280x720) class display and an interactive and more sophisticated HMI utilizing camera input or various types of sensors (more info).
