FT313HQ-T

Controllers Overview

The FT313HQ-T is a Hi-Speed Universal Serial Bus (USB) Host Controller manufactured by Future Technology Devices International Ltd. It is compatible with the USB Specification Rev 2.0 and supports data transfer speeds of up to 480 Mbit/s. The device integrates an internal voltage regulator that supplies 1.2V to the digital core, allowing for low power consumption suitable for portable applications. It supports bus interface I/O voltages ranging from 1.62V to 3.63V and features hybrid power mode capabilities where VCC(I/O) can be powered without VCC(3V3). The controller includes a single USB host port supporting high-speed, full-speed, and low-speed data transfers.

Controllers Feature Summary

• Compatible with Enhanced Host Interface Specification Rev 1.0
• Supports Battery Charging Specification Rev 1.2 with configurable downstream ports
• Integrates USB 1.1 host functionality within the USB 2.0 EHCI compatible controller

Controllers Applications

• Portable electronic devices requiring low power consumption
• Systems utilizing hybrid power modes
• Battery charging applications with current control requirements

Controllers Procurement Notes

Verify the specific suffix 'T' against official FTDI documentation to confirm packaging or tape-and-reel specifications. Ensure compatibility with the required I/O voltage range of 1.62V to 3.63V for your system design. Confirm that the device meets the necessary environmental operating temperatures if deployed in industrial conditions.

Controllers Selection Notes

Select this component when a single-port USB 2.0 Hi-Speed host solution is required with integrated power management features. The internal voltage regulator simplifies board design by eliminating the need for external 1.2V generation. Consider the LQFP-64 package constraints during PCB layout planning.

Controllers Part Context

The FT313H series represents FTDI's embedded host controller line designed for USB 2.0 compliance. This family focuses on reducing system complexity and power usage in mobile and battery-operated devices through integrated regulation and hybrid power support options.
