Hi Andrey,
I have some news from the fab today and I have a meeting with them tomorrow
morning.
They sent me the BOM with components price list. This bring me a few
questions.
1/ Would you know a distributor for the Murata chokes ? The fab them to
have some issue to source these.
2/ Would you suggest a distributor for the GPS chip ?
3/ The CY7C1460AV33-167AXI costs more than 50 Euros on the list ! I know
SRAM is expensive but would you know where we could purchase this component
at a lower price ? If not, do you think we could use a cheaper but
equivalent SRAM chip ?
4/ The M25P64-VMF6 costs more than 20 Euros on the list ! This is huge for
a 64M flash. Would you know where we could purchase this component at a
lower price ? If not, do you think we could use a cheaper but equivalent
flash chip ?
Please let me know about this. This would help me a lot to move forward to
the next sample production step.
Thanks a lot for your help.
Best regards.
Jean-Samuel.

Hi Andrey,
I sent the files last week. The fab needs a few days to update its pricing
and launch the production process.
Anyway, I just called them today. Work is in progress. They will provide
me with some updates later this week. They confirm this should not take too
much time for production and they will anyway contact me if they need
anything.
I will let you know asap.
Best regards.
Jean-Samuel.
