Description

The RZ/A1M Group MPUs are full-featured with an Arm® Cortex®-A9 core running at 400MHz and 5MB of on-chip SRAM. With 5MB on-chip SRAM, the RZ/A1M supports up to 2 Displays with WSVGA (1024x600) resolution or a single display with WXGA (1280x800) resolution without the need for external memory. RZ/A1M enables very compact embedded designs without the need to worry about memory procurement and memory EOL. With RZ/A1M, you can design your embedded system like an MCU and get the performance of a 400MHz Arm® Cortex®-A9 MPU. Enabled for support with Linux, RTOS or Bare-metal, this is the ideal device for designing Intelligent IoT End Point devices with compactness and high performance. Supported in QFP and BGA packages with different sizes to support board layout flexibility and with SDRAM interface to expand up to 128MB of external memory. Get Started Using RZ/A1 MPUs.

  1. How to handle the Y2K38 issue on RZ/A1M running 3.14.79-ltsi kernel

    Hi, Anyone have a workable solution to handle Y2k38 issue on 32bit renesas processors with linux? Initially I was in an assumption that a fix/upgrade to glibc should solve this issue, but the issue is far deeper that i thought, the Kernel should be migrated to 5.1 ...

  3. RZ/A: Concerns and restrictions when using SSCG

    Some clocks do not change even when the SSCG function is used. Deep standby mode cannot be used when using the SSCG function. In addition, it is necessary to satisfy "SSCG stabilization time (tSSCG)" as an electrical characteristic.For details, refer to the user's manual.
