External memory

lgs

Can the nFR52840 connect the FRAM memory by the SPI or QSPI interfaces? The document describes it can connect the flash memory.

    Hi,

    The nRF52840 should be able to connect to and control any SPI peripheral devices. The QSPI interface is designed to interface external flash devices. If it is compatible with the interface of your FRAM memory depends on the memory. You need to check the datasheet of the memory of interest and compare it to the Instruction set defined in the QSPI peripheral in nRF52840.

    Best regards,
    Jørgen

    Thanks. Do you have a product that supports BLE Mesh Network with a FRAM memory rather than flash memories?

    I check the document about mesh network it says " As the Bluetooth mesh stack uses the flash to store state across power failure, the device flash will eventually start failing, resulting in unexpected behaviour in the Bluetooth mesh stack".
