The FPC401 quad port controller serves as a lowspeed signal aggregator for common port types such as SFP+, QSFP+, and SAS.

1 Supports Control Signal Management and I2C Aggregation Across Four Ports.
Combine Multiple FPC401s to Control 56 Total Ports Through a Single Host Interface.
Eliminates Need for Discrete I2C Muxes, LED Drivers, and High-Pin-Count FPGA/CPLD Control Devices.
Reduces PCB Routing Complexity by Handling All Low-Speed Control Signals Close to the Port.
Selectable I2C (Up to 1 MHz) or SPI (Up to 10 MHz) Host Control Interface.
Automatic Pre-Fetchi.
