PM42100B-FEI

PM42100B-FEI Description

The PM42100B-FEI from Microchip Technology is a high-performance PCIe Switch designed for Gen4 Backplane applications. Packaged in a BBGA (Ball Grid Array) format, this surface-mount component supports PCI (Peripheral Component Interconnect) interfaces, enabling high-speed data transfer in complex computing environments. With a dual-voltage supply (0.82V and 1.8V), it ensures efficient power management while maintaining signal integrity. Although marked as Obsolete (ECCN: OBSOLETE), it remains ROHS3 Compliant, adhering to environmental standards. Its Moisture Sensitivity Level (MSL 4) requires careful handling within 72 hours of exposure.
