Renesas Electronics Corporation introduced a new high-performance microprocessor (MPU) in the RTOS-based RZ/A series that meets the growing demands of advanced human-machine interface (HMI) systems. The new RZ/A3M MPU comes with large SDRAM, SRAM and RTOS support to facilitate the seamless execution of complex tasks and real-time graphical displays. The RZ/A3M drives video and camera output on large LCD panels with resolutions up to 1280x800, addressing the display requirements in next-generation home appliances, industrial and office automation, healthcare devices and building control systems.
Similar to its existing RZ/A3UL, the RZ/A3M features a 64-bit Arm® Cortex®-A55 core with a maximum operating frequency of 1 GHz and 128 KB (kilobytes) of on-chip SRAM. By integrating high-speed 128MB DDR3L-SDRAM in a single System-in-Package (SiP), the device eliminates the complex task of designing a high-speed signal interface for connecting external memory (more info).
