OpenBMC and Boot flash memory chip types?

(1/1)

FlyingBlackbird:
According to the schematics the Boot flash memory chip should be a MT25QL512ABB8ESF-0SIT (Micron),
see the data sheet at https://www.digikey.com/product-detail/en/micron-technology-inc/MT25QL512ABB8ESF-0SIT-TR/557-1987-1-ND/9673968)

Looking at my Blackbird planar I found an (to me) unknown chip (the logo looks like the Micron logo though):

7RAI5 RWI87 258

Does anyone know this chip and could even post a data sheet here?

MPC7500:
RW187 ;)

THX! So  RW187 is the FBGA code of Micron, now I understand:

> Due to space limitations, FBGA-packaged components have an abbreviated part marking that is different from the part number.
> Micron's FBGA Part Marking Decoder makes it easier to understand that part marking.
> The FGBA code is the second 5-digit code found in the chip marking.
> Simply enter the five-digit code in the FBGA Code field and click "Search" to get the full part number.
