ADSP-2147x pin compatible

I am thinking that the internal RAM capacity of ADSP-21479KCPZ-1A is increased without external RAM.
Is ADSP-21477KCPZ-1A pin compatible with ADSP-21478KCPZ-1A and ADSP-21479KCPZ-1A?

    Hi Hyamashita,

    I am thinking that the internal RAM capacity of ADSP-21479KCPZ-1A is increased without external RAM.

    >> Yes, the internal RAM of ADSP-21479 is higher (5 Mbits) when compared to ADSP-21478 (3 Mbits) and ADSP-21477 (3 Mbits). You would find the  ADSP-2147x family features on Table 2 given in the ADSP-217x datasheet.

    Is ADSP-21477KCPZ-1A pin compatible with ADSP-21478KCPZ-1A and ADSP-21479KCPZ-1A?

    >> Yes, the "ADSP-21479KCPZ-1A" has 88-Lead LFCSP_VQ pin package which is pin compatible with ADSP-21478KCPZ-1A and ADSP-21479KCPZ-1A processors.Thanks,
