Hello,
Yes, the lead time is 52 weeks minimum for S32K1 devices.

So if there is nothing directly in stock, 52 weeks is minimum delivery time.
1. Why is the supply and lead-times still a problem when the "chip shortage" should have eased?
2. For this particular part FS32K148UJT0VLLT, how to get more details on the likely dates of getting supply? ...or is production restart for this particular SKU NOT planned/scheduled at all.
There no such thing as production restart. Chips are being produced at max factory capacity. There is simply too much demand.
“There’s this wishful thinking that by the end of 2022, supply will be balanced with demand,” said Tom Caulfield, chief executive of contract chip manufacturer GlobalFoundries Inc. “I just don’t see it.”
Best regards,
Peter
