AWR1642: Compatible SPI flash list in AWR1642 ES2.0

Adam Yao94020

Part Number: AWR1642

Hi champion,
   Due to the restriction in boot loader, we only support very limited Flash models in AWR1642 ES1.0. Some of them are too old to do new design. My customer want to check do we have list for AWR1642 ES2.0 supported Flash? Especially they want to use IS25LP080D-JULA3 from ISSI, do we have plan to support in ES2.0?

Thanks,
Adam

    Hello Adam,

    Hi Adam,

    We have the restriction on interop with limited Flash models only with the XWR12xx and XWR14xx pre-production devices. The AWR1642 ES1.0 devices supports a more wider range of SFLASH part variants from different vendors. We have checked the working of AWR1642 ES 1.0 device with the available off the shelf ISSI part variant (IS25LQ016B-JBLE - by setting the QE bit once) as well.

    Please refer to the post e2e.ti.com/.../639898 for more information on the key considerations for interop.

    Best regards,
    Naveen

    Hello Naveen,
    Customer tried the IS25LP080D-JULA3, but it could not connect to AWR1642. I checked the post in your last reply.
    __________________________
    Recommendation:
    The flash vendors have an orderable part variant with the Quad Enable (QE) bit set. It is recommended to use these variants to work with TI mmWave SOCs.
    __________________________

    Could you double check whether AWR1642 can work with a IS25LP080D-JULA3 model with QE bit set? Customer worry there is other issue which prevent the interop.

    Thanks,
    Adam
