RZ/A1M is a full-featured part in the RZ/A1 family with an Arm® Cortex®-A9 core running at 400MHz and 5MB of on-chip SRAM to support large frame-buffers on-chip.
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.

Hardware Design Support
|IBIS/BSDL||IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board. BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.|
