Subject: Device Types:
Process Change Notification
PSD4XX Family Devices (except 403)
Including ZPSD Versions Including Both Volt Volt Versions Including Speeds, Packages, Temperature Ranges
Background Plan
WSI's PSDs continue gain acceptance marketplace. order assure consistent flow products worldwide, continuing process moving production into fabrication facilities offering additional capacity. Currently PSD4XX production shipments produced WSI's micron process Fairchild Semiconductor. Both facilities (SGS Thomson Tower Semiconductor) using WSI's micron process. Both these facilities have fully qualified 0.6-micron process currently production with PSD211R PSD3XX product families. This notify intent meet increased demand future performance goals product line supplying product from both fabrication lines. Initially shipments PSD4XX will come from facility Thompson eventually will phase Tower Semiconductor. will phase facility Fairchild with these products upon successful conversion customers 0.6-micron product.
Form, Fit, Functional Changes
products have been thoroughly tested verified multiple customer beta sites. Product programming been verified WSI's third party preferred programmers addition WSI's MagicPro programmer. programming algorithm change required.
