RZ/A3UL Group of Microprocessors

Renesas Electronics Corporation has announced the new RZ/A3UL group of microprocessors (MPU) that enables both a high-definition human-machine interface (HMI) and quick startup for applications requiring high throughput and real-time capabilities. This 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 and this feature is ideal for systems that require a fast response time such as industrial equipment, homeless appliances, and office automation equipment with liquid crystal displays or control panels, along with audio equipment and POS terminals. It 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 the connection of high-speed DRAM.

Key Features of RZ/A3UL Group of MPUs

  • Cortex-A55 (Single)

  • LCD Controller

  • Camera interface (MIPI-CSI)

  • Display interface (Parallel-IF)

  • USB2.0 interface 2ch, SD interface 2ch

  • CAN interface (CAN-FD)

  • Gigabit Ethernet 2ch

  • Memory error detection / correction (ECC)

  • OctaRAM or DDR4/DDR3L memory interface

  • BGA package (13 x 13mm)

The peripheral functions and package pin assignments of the RZ/A3UL MPUs are compatible with the RZ/G2UL that employs the Cortex-A55 core targeting Linux-based HMI applications, and with the RISC-V-based RZ/Five products. The RZ/A3UL MPUs and development tools are now available.
