• ADSP-BF522 silicon rev serial flash compatibility

    Good morning

    Are all the silicon rev of the ADSP-BF522 compatible with NOR serial 24-bit address flashes?

    Thanks

  • 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。
