Do “Once available stock of this product has been depleted, manufacturer standard package and lead time will apply.” mean “Microchip will not produce 45-WLCSP for ATSAMD21G18A-UUT anymore” ?


That message indicates that the part is being converted to non-stock status at DK, and therefore that orders placed for it after existing stock is depleted will have to be ordered in in the manufacturer’s standard package quantity and will subject to the manufacturer’s indicated lead time for delivery.

It’s status is still listed as “active” at this time so it’s not a matter of MCHP discontinuing production.
