Hello, could someone help me with identifying this chip? What package is this?

I wonder if it's possible to determine pinout for this chip. There is a place for standard TSOP48 package. So, when I measure continuity from TSOP48 pads to those pads 3x10 I should find which ones are connected. Am I right or totally wrong?

Thank you for help.

Yes, this is standard 3x10 UFD Sandisk pinout, you can find it in VNR and PC3K database, you can also do measure continuity from TSOP48.

Thank you for reply Gregory.
So, here are my measurements.

Is this correct?

It looks like monolith number 0153 from VNR database.

Exactly this is it, ofc you measured on the PCB so you have a mirror image of the pinout

Yep, I know. Thank you very much.

I soldered it to monolith universal adapter but can't read ID in VNR. Maybe it's a waste of time with this capacity. It's 256 GB device. So I don't think there is a solution in VNR database.

Most flash don't have solution. You need try develop.
