Attached Qualification Report. Provided estimated first ship date to be on October 31, 2025.
Description of Change: Qualification of Microchip Technology Colorado ? Fab 5 (MCSO) as a new fabrication location for multiple device families available in various packages.Reason for Change: To improve manufacturability and on time delivery performance by qualifying a new fabrication location (MCSO - FAB 5), which is a Microchip-owned facility that offers significant expansion potential to better meet future client demand. *Note: The attached file called Tempe_Fab2_IATF_Decertification is for the manufacturing site deactivation of Microchip Technology Tempe ? Fab 2 (TMGR), contact your local Microchip sales office for inquiries.Estimated Qualification Completion Date: September 2025Pre and Post Summary Changes:? Pre Change: Fabrication Site = Microchip Technology Tempe ? Fab 2 (TMGR), Wafer Size = 8"? Post Change: Fabrication Site = Microchip Technology Colorado(MCSO), Wafer Size = 6"
