Hi there.

I need to know the name of this bga 12 chip from this Xiaomi motherboard.

It is like the NX5P3290 but only have 12 balls, not 16 as NX5P3290 have.

Sorry for the quality of photos. (it's the best I can get with my smartphone)

Marking code UA704?

UA704 is what is written neaar it on motherboard.

I've found the NX20P0407UKAZ have the same number of pins, but don't know it is a direct equivalent.

There's no schematic nor boardview, so it's difficult to say.

Here's the pdf for NX20P0407UKAZ:

for example NX5P3290 Marking Code X5PT4
What marking IC UA704?

The inscription in top of chip is:
HERU (perhaps HEAU)
H1D

I'm googled for "heru h1d" and cant find any good answer.

Also "heau h1d top marking code" and same.

Does that inscription says something for you?

Thanks for your help.

Hi, I'm still with this laptop.

I have received a few NX5P3090 (X5PT2) that has the same number of pins (balls) that the one I need, but it is smaller.

The X5PT2 is "wafer level chip-scale package; 12 bumps; 1.65 x 1.35 x0.525 mm; 0.4 mm pitch" according to datasheet.

The one I need is "wafer level chip-scale package, 12 terminals, 0.4 mm pitch, 1.97 mm x 1.42 mm x 0.525 mm" according to SOT1390-10 datasheet.

I tried to find an equivalent to NX5P3090 a bit longer (1.97 mm x 1.42 mm x 0.525 mm) but no luck till now.

I'm still trying to find out the original one.

I will appreciated any help.

Thanks.
