Nor Flash compatible check

Hello,

My customer is checking new Nor Flash part because the current part has EOL issue. 

They are using this Flash for Boot.

 - main DSP: ADSP-BF609

 - current NAND Flash(EOL issue): PC28F128P33

 - New NAND Flash: MT28EW_QLHP_128_ABA_0SIT 

 

Please check that New Flash(MT28EW_QLHP_128_ABA_0SIT) is OK for Black pin DSP(ADSP-BF609)

Kind Regards,

MJ Kim

  • Hi LalithaS,

    Here are the more checking points from the customer.

    Please check it.

    [new flash: MT28EW_QLHP_128_ABA_0SIT]

    1. They connected 'SMC0_AOE' to 'ADV#' pin in the previous flash, but they cannot find the connection pin for this in a new flash. please guide it.

    2. They connected 'SMC0_ARDY 'to 'WAIT 'pin in the previous flash. then they plan to connect it to 'RY/BY#' pin in a new flash.

        Is it OK for timing related things? please check it.

    Thank you.

    Hi Kim,

    Sorry for the delayed response. Please find the solution below.

    Regarding,"They connected 'SMC0_AOE' to 'ADV#' pin in the previous flash, but they cannot find the connection pin for this in a new flash. please guide it."

    >> There is no similar pin as like “Address Valid (ADV)” in your new flash part. You can use this pin as a test point from 'SMC0_AOE' pin for reference purpose, because this pin is output.

    Regarding,"They connected 'SMC0_ARDY 'to 'WAIT 'pin in the previous flash. then they plan to connect it to 'RY/BY#' pin in a new flash."
    >> You can connect  'SMC0_ARDY’ pin to 'RY/BY#' and use 10 Kohm Pull-up resistor for this pin.

    Regards,
