• ADSP-BF522 EBIU

    Hi,
    I'm new to development with this family of DPS and i'm interested in using ADSP-BF522, I have only one doubt related to the EBIU.
    The datasheet says: "External memory is accessed via the EBIU.
    This 16-bit interface provides a glueless…
  • The difference between ADSP-BF523 and ADSP-BF522 When used Host DMA

    Hi:

    I'm a disty dedicated FAE for ADI, Now there is a issues about ADSP-BF522 in my customer:

    They used ADSP-BF523 with Host DMA Download, it worked normally, and it's mass production;

    When it's replaced by ADSP-BF522 with no change in the…

  • 请问ADSP-BF522的外围内核上电顺序。

    请问ADSP-BF522是不是外围VDDEXT,VDDMEM先上电,然后VDDINT内核再上电。

    目前设计是5V外部供电经过BUCK电路形成3.3V给ADSP-BF522的外围VDDEXT,VDDMEM上电。

    再由3.3V经过LDO形成1.3V给ADSP-BF522的VDDINT内核上电。

    VRSEL管脚制高电平,选择外部电压调节模式。

    PG管脚使用3.3V电阻分压形成0.82V供给。

    请问这样的顺序是否正确。芯片工作在FULL ON状态下。

  • RE: BF527 Multi-cycle Instructions and Latencies. any document?

    yes,

    e.g. in the datasheet of BF-527, it sais the family has following processors:

    ADSP-BF522/ADSP-BF523/ADSP-BF524/ADSP-BF525/ADSP-BF526/ADSP-BF527

    but you said previously

    "2) The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors belong to the same…
  • RE: power up sequence for BF527

    Hi,

    The anomaly will appear in Rev D of the BF522/4/6 list and Rev F of the BF523/5/7 list. We anticipate that the updated BF522/4/6 list will appear online at the end of the month and the BF523/5/7 list will go online sometime next month.

  • BF527 PLL setting

    Could you explain me which way of PLL setting for BF527 is correct?

    There is information:

    "Note that the divisor ratio must be chosen to limit the system

    clock frequency to its maximum of fSCLK. The SSEL value can be

    dynamically changed without…

  • SSM2603 I2C port occasionally stops working

    I am using an SSM2603 controlled by a BF522. During normal operation the BF522 configures the SSM2603 over I2C and everything works OK. Occasionally (1 time in 1000 or so) the I2C interface stops working. The BF522 sends the address & write/read bit,…
