The FPC402 aggregates all low-speed control and I2C signals across four ports and presents a single easyto-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. The FPC402 is designed to allow placement on the bottom side of the PCB, underneath the press fit connector, to simplify routing. This localized control of the low-speed signals in the ports cuts system BOM costs by enabling the use of smaller IO count control devices (FPGAs, CPLDs, and MCUs) and by reducing routing layer congestion. 1 • • • • • • • • • • Control Signal Management and I2C Aggregation Across Four Ports Combine Multiple FPC402s to Control 56 Total Ports Through a Single Host Interface Eliminate Need for Discrete I2C Muxes, LED Drivers, and High-Pin-Count FPGA/CPLD Control Devices Reduce 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 Prefetching of Critical, User-Specified Data From the Modules Broadcast Mode Write to All Ports Simultaneously Across All FPC402 Controllers Advanced LED Features for Port Status Indication, Including Programmable Blinking and Dimming Customizable Interrupt Events Separate Host-Side I/O Voltage: 1.8 V to 3.3 V Small WQFN Package Enabling Placement on Bottom Side of PCB Underneath Ports 2 Applications • • • • • Device Information(1) PART NUMBER FPC402 PACKAGE BODY SIZE (NOM) WQFN (56) 5.00 mm × 11.00 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.

ADVANCE INFORMATION 2 Submit Documentation Feedback Copyright © 2017, Texas Instruments Incorporated Product Folder Links: FPC402 FPC402 www.ti.com SNLS583 – JUNE 2017 5 Description (continued) The FPC402 is compatible with standard SFF-8431, SFF-8436, and SFF-8449 low-speed management interfaces, including a dedicated 100- or 400-kHz I2C interface to each port. Additional general-purpose pins are available to perform functions such as driving port status LEDs or controlling power switches. The LED drivers have convenience features such as programmable blinking and dimming. The interface to the host controller can operate on a separate supply voltage between 1.8 V and 3.3 V to support low-voltage I/Os. ADVANCE INFORMATION The FPC402 can prefetch data from user-specified registers in each module, making the data readily accessible to the host through a fast I2C (up to 1 MHz) or SPI (up to 10 MHz) interface. In addition, the FPC402 can trigger an interrupt to the host whenever critical, user-configurable events occur associated with any of the ports the device controls. This eliminates the need to continuously poll the modules.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 6.6 Glossary SLYZ022 — TI Glossary.
