FT313HQ-R

Controllers Overview

The FT313HQ-R is a USB High-Speed Host Controller IC manufactured by FTDI, belonging to the FT313 series. It complies with the USB 2.0 specification and supports data transfer rates up to 480 Mb/s. The device integrates a USB 1.1 host controller within the EHCI-compatible architecture and features a QFN-64 surface-mount package. It operates on a supply voltage range of 1.62 V to 3.63 V, with a minimum operating voltage of 2.97 V and a maximum of 3.63 V. The component draws a working power current of 35 mA and functions within a temperature range of -40°C to +85°C. It supports Full Speed (FS) and Low Speed (LS) modes in addition to Hi-Speed.

Controllers Feature Summary

• Integrates an internal voltage regulator that supplies 1.2V to the digital core.
• Supports hybrid power mode allowing operation when VCC(3V3) is absent but VCC(I/O) is powered.
• Compatible with the Enhanced Host Interface Specification Rev 1.0.
• Configurable downstream port supporting SDP, CDP, or DCP modes per Battery Charging Specification Rev 1.2.

Controllers Applications

• Portable devices requiring low-power USB host connectivity.
• Systems utilizing bus interface I/O voltages between 1.62V and 3.63V.
• Applications requiring integrated battery charging specification support.

Controllers Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity for the QFN-64 form factor upon receipt. Check for moisture sensitivity indicators as the device is humidity-sensitive. Validate revision markings against official datasheets to ensure compatibility with existing designs.

Controllers Selection Notes

Select this component for designs requiring a single-chip USB 2.0 Hi-Speed host solution with integrated power management. Ensure the application board supports the required 1.62V to 3.63V I/O voltage range. Consider the QFN-64 thermal dissipation requirements for the specified operating temperature range.

Controllers Part Context

The FT313HQ-R is part of the FT313 family from Future Technology Devices International Ltd. It serves as a specialized interface IC for USB host applications. The 'R' suffix typically denotes reel packaging, distinguishing it from tape or cut-tape variants like the FT313HL-R.

Controllers Replacement Considerations

The FT313HL-R is a related variant within the same series, differing primarily in package type (LQFP-64 vs QFN-64). Verify pinout compatibility before substitution. No other direct public substitutes are confirmed in available documentation.
