FPC401RHUR

Specialized Overview

The FPC401RHUR is a specialized quad port controller manufactured by Texas Instruments, designed for high-density interface management. It operates within a supply voltage range of 1.8V to 3.3V and utilizes an I²C interface for host communication. The device is housed in a 56-WQFN (5x11) package with an exposed pad, suitable for surface mount installation. It supports operation across an industrial temperature range from -40°C to +85°C. A key capability is the aggregation of four ports per unit, allowing multiple devices to be combined to control up to 56 total ports through a single host interface, thereby eliminating the need for discrete I²C components.

Specialized Feature Summary

• Aggregates control across four distinct ports per device
• Enables expansion to 56 total ports via single host interface
• Eliminates requirement for discrete I²C circuitry

Specialized Applications

• High-density display panel control systems
• Multi-port interface aggregation hubs
• Embedded systems requiring consolidated I²C management

Specialized Procurement Notes

Verify the specific suffix RHUR against the required package dimensions and thermal characteristics. Confirm that the 56-WQFN footprint matches the PCB layout constraints. Ensure the operating temperature range of -40°C to +85°C meets the environmental requirements of the target application. Cross-reference the I²C address settings to prevent bus conflicts when aggregating multiple units.

Specialized Selection Notes

Select this component when a compact solution is needed to manage multiple peripheral interfaces without increasing board complexity. The quad-port architecture reduces the number of host connections required compared to single-port alternatives. Consider the 56-WQFN package size for space-constrained designs. Verify compatibility with the system's I²C clock speeds and voltage levels before integration.

Specialized Part Context

The FPC401 series serves as a specialized interface controller within Texas Instruments' portfolio, focusing on simplifying multi-port connectivity. The RHUR variant specifically denotes the 56-WQFN package configuration. This component addresses the need for efficient port expansion in applications where discrete logic would otherwise increase component count and design effort.

Specialized Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate other Texas Instruments quad port controllers or I²C expanders based on pin compatibility and package dimensions. Verify functional equivalence regarding port aggregation limits and voltage ranges before substitution.
