FPC401 Texas Instruments Datasheet

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
