ON Semiconductor announced "Last Buy Status" for its HAS2 space-certified start tracking sensor:
"In July 2011, the silicon supplier producing the HAS2 wafers for ON Semiconductor announced with short notice that they would be discontinuing manufacture of this product. At that time, ON Semiconductor was required to follow industry Product Change Notification procedures and put its HAS2 image sensor on a ‘Last Time Buy Status’. Where
applicable, special arrangements have been made with existing customers to minimize the impact of this transition. In parallel, I want to assure you that ON Semiconductor has secured ample product inventory to supply this product to customers to service their predicted full lifetime needs with margin."
