What are the external memory types supported with RA8 Series MCUs

And can the RA8 Series MCU's support HyperFlash and HyperRAM devices?

  • Hi June, 

    Thank you for your post!

    RA8 Series MCUs support xSPI compliant Octal SPI (OSPI) interface with support for Execute-In-Place and Decryption-on-the-fly (DOTF). The OSPI interface is compliant with JEDEC standard JESD251 (Profile 1.0 and 2.0), JESD251-1 and JESD252.

    The RA8 Series is compatible with all flash devices that are JESD251 standard compliant and support both Octal Flash & Octal RAM and HyperFlash & HyperRAM devices that are compatible with the Infineon HyperBus specification. RA8 xSPI guarantees operation with JESD251 (xSPI for Non-Volatile Memory) compliant memory.

    The RA8 series MCUs have been tested and are confirmed to be compatible with these memory P/Ns.

  • Hi,

    This is to updated about APMemory OPI RAM validation done at our Lab based on EK-RA8M1

    64Mb OPI 3V BGA24, both Xccela (APS6408L-3OBM-BA) and OctaRAM (APS6408L-3OC-BA) protocol has been validated

    Overall available IoT RAM  (1.8V & 3V) covers 64Mb/128Mb/256Mb/512Mb OPI (11 pins, up to 200MHz) BGA24 & WLCSP, as well as 16Mb/64Mb/128Mb QSPI (SDR 6pins or DDR 7pins) in SOP8/USON8/WLCSP.
