FPC402 Quad Port Controller

Texas Instruments FPC402 Quad Port Controller serves as a low-speed signal aggregator for common port types such as SFP, QSFP, Mini-SAS HD, and others. The FPC402 aggregates all low-speed control and I²C signals across four ports and presents a single easy-to-use management interface to the host (I²C or SPI). Multiple FPC402s can be used in high-port-count applications with one common control interface to the host. To simplify routing, the Texas Instruments FPC402 is designed to allow placement on the bottom side of the PCB, underneath the press-fit connector. This localized control of the low-speed signals in the ports cuts system BOM costs by enabling smaller IO count control devices (FPGAs, CPLDs, and MCUs) and reducing routing layer congestion.
