FT313H - High speed USB 2.0 embedded host controller IC

The FTDI FT313H is an enhanced general purpose USB 2.0 Hi-Speed USB Host controller, designed for integration with microcontrollers via parallel bus options and offering battery charger emulation on the downstream port to support higher charging currents.

The FTDI FT313H is a high speed Universal Serial Bus (USB) Host Controller compatible with Universal Serial Bus Specification Rev 2.0 and supports data transfer speeds of up to 480Mbit/s.

It is offered in 64-pin LQFP, TQFP and QFN packages.

Key features:

  • USB 2.0 Hi-Speed Host, EHCI compatible, single port IC
  • Supports multiple bus interfaces. 8-bit or 16-bit bus for GPIO, SRAM or NOR Flash
  • Support Bulk, Isochronous, Control and Interrupt transfers
  • Split transaction support for external USB hubs
  • Single power supply operation at 3.3V
  • 1.8V, 2.5V and 3.3V IO levels supported
  • 24kBytes high speed RAM memory
  • Battery Charger Emulation (BCD 1.2) to allow downstream devices to request higher currents
  • Extended operating temperature range : -40°C to 85°C.
