Development Module

The UMFT313EV is a development module for FTDI's FT313H. The UMFT313EV is used to develop and demonstrate the functionality of the USB2.0 Hi-Speed Host Controller. This module can provide three kinds of asynchronous bus interface to connect with a microcontroller.



The UMFT313EV utilises the FTDI FT313H QFN package. All the features of the FT313H can be accessed with the UMFT313EV. For a full list of the FT313H's features please see the FT313H datasheet.In addition to the features listed in the FT313H datasheet, the UMFT313EV has the following features:

  • Standard USB-A receptacle allows module to be connected to USB devices
  • Supports self power or power from the microcontroller platform
  • Provides configuration switch for module system frequency selection and BCD mode configuration
  • Provides button for module hardware reset
  • On board 2x20 pins 2.54mm (0.1") pitch female headers allowing easy connection to microcontroller platforms
  • Provides probe header for customer debugging
