Renesas’ MPU provides high speed processing and throughput with the full potential of a real-time operating system (RTOS).

Renesas Electronics Corporation has launched the RZ/A3UL group of microprocessors (MPU). The MPU provides users with high definition Human-Machine Interface (HMI) and quick startup for applications that require high throughput and real-time capabilities. The 64-bit Arm Cortex provides a maximum operating frequency of 1GHz that enables performance boost.

The other versions of the device are available with DDR3L/DDR4 memory interface that is used for connecting with high speed DRAMs. The basic MPUs consist of Octal-SPI memory interface which enables simpler and more compact boards. But the DDR3lL/DDR4 provides 10x faster performance for utilizing the HMI utilizing cameras and various other sensors.

“Many customers who use RTOSes tell us that they want to retain features like excellent real-time capabilities and quick startup, but that they also want higher resolution and better performance,” said Shigeki Kato, Vice President of the Enterprise Infrastructure Business Division at Renesas. “I am confident that the RZ/A3UL will deliver the higher performance required, while still giving customers the flexibility and ease of use offered by MCUs.”
