FPC401 Overview
The FPC401 quad port controller serves as a lowspeed signal aggregator for mon port types such as SFP+, QSFP+, and SAS. The FPC401 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 FPC401s can be used in high-port-count applications with one mon control interface to the host.
FPC401 Key Features
- 1 Supports Control Signal Management and I2C Aggregation Across Four Ports
- bine 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 plexity 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-Fetching of Critical, User-Specified Data From the Modules
- Low Single-Port and Multi-Port Read/Write Latency: <50 µs for SPI Mode, <400 µs for I2C Mode
- Broadcast Mode Allows Writes to All Ports Simultaneously Across All FPC401 Controllers
- Advanced LED Features for Port Status Indication, Including Programmable Blinking and Dimming
- Customizable Interrupt Events
