Hi friends, I was using an ARM9 STR912FW44 in my projects.

Last week i was projecting another system and i was searching ST Microelectronics website for the STR912FW44 datasheet.

Surprisingly i found that there is another STR912, but this time it has FAW44 on the chip spec. What this FAW means ?

I downloaded both datasheets and i found no difference between them.

Thanks for the attention

The STR91xFxxxxx are the first samples with silicon revision B and D and the STR91xFAxxxxx are the last samples(production devices) with silicon revision G and H.

Refer to STR91xFA errata sheet for more information:
