| Post subject: | Flash Chip Identification | ||
This chip was given to me with a flash drive that doesn't fit. I haven't been able to identify the bga or find anything that looks like it. The flash drive board looks like many others (BGA 152 I believe). Notice there are 3 rows of pins where the bga152 has four. Any help appreciated greatly. Chip markings: PF079-10AL 1534

Tried chip off recovery? |

I know very little about chip off. Have done some iphone nand repair with the blue box. I think I have confirmed this is BGA 132 but it can be read with other sockets right? |

It is BGA 132 if you look at the standard, it is a valid configuration. Search for in google: bga 132 152 onfi, and open the 4mb .pdf standard. look at page 23: http://www.onfi.org/~/media/onfi/specs/onfi_3_2-gold.pdf You can use the same adapter as 152, and if chip is different dimensions, then use a space/frame whatever you want to call it. The middle 88 pins are the ones the adapter uses on both 152, and it's subset, 132. I actually have one that is 108, with even less pads. http://forum.hddguru.com/viewtopic.php?f=10&t=37127 you can use a part number decoder to get the PF "marking" back to the full part number, then find a datasheet, but you shouldn't need the DSheet. BTW, some of these have 8 CE's so you have to be mindful of that. |

Ahh ok, so you probably don't have one of the big 3 NAND readers. Was suggesting to use the NAND reader and find out chip ID and go from there. |
