Frequently Asked Questions (FAQ)
Revision 1 – February 25, 2016
Why is Microchip making this change? The Micrel 6 inch
fabrication facility in San Jose is closing. The Microchip 8 inch
fabrication facilities will provide more capacity that will ensure
continuity of supply. Microchip’s fabrication sites have
improved defect control/inspections and more
efficient/diversified fab equipment.
