The two possible components of an ASIC that can go obsolete are the processing and the packaging. Swindon will choose a process with longevity in supply attached to it and most packages can be sourced from more than one supplier. Swindon will even port the design onto a new process if required as a foundry will normally provide 2 years notice of obsolescence. The important fact to note is that Swindon will provide assistance throughout and will not leave the customer in a situation where obsolescence becomes a major issue. A last time buy of packaged devices is a major financial outlay and Swindon aim to find a solution for our customer long before that scenario develops.
