Overview

RZ/A1H is the premium full-featured part in the RZ/A1 family with an Arm® Cortex®-A9 core running at 400MHz and 10MB of on-chip SRAM. With 10MB on-chip SRAM, the RZ/A1H supports up to 2 Displays with WXGA (1280x800) resolution without the need for external memory. RZ/A1H enables very compact embedded designs without the need to worry about memory procurement and memory EOL. With RZ/A1H, 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.
