TDA2P-ACD: balls AA1,AA2,AB1,AB2,AC1,AC2

Part Number: TDA2P-ACD
Other Parts Discussed in Thread: TDA2, DRA77P

Hi.

(1) There is no mech.drawing of ACD(784-balls)-package in datasheet.

Do I need to use ABC(760-balls)-package drawing as reference for my design? (Does it have the same size and pitch? Is ABC the same as ACD but only 24 balls are excluded?)


(2) There are no any description about 6-balls in TDA2P-ACD-datasheet: AA1,AA2,AB1,AB2,AC1,AC2.
Where I can find info about Pullup or Pulldown requirements for these balls if they are unused?
These balls marked as MLBP-pins in SD TDA2P_EVM design (see picture).


Is DRA7x TRM applicable for reference TDA2 MLBP description?

But, do I need to use DRA7xxP datasheet for reference about these balls?

---

best regards

    Hi Arseniy,

    1. As layout - yes, ACD is the same as ABC, but includes missing balls - 23 mm × 23 mm, 0.8-mm Pitch. Note that ball-mapping is different - they are not pin compatible! Please also note that ACD have different dimensions:


    2. Yes, these balls are unused in TDA2P devices. You should leave them unconnected.

     

    Thanks,
