FT201X USB 2.0 to I²C Bridge (Slave) Interface Evaluation Board

Description of product


The UMFT201XA is a development module for FTDI’s FT201XQ, one of the devices from FTDI’s range of USB interface bridging integrated circuit devices. FT201X is a USB to I 2C interface with a battery charger detection feature, which can allow batteries to be charged with a higher current from a dedicated charger port (without the FT201X being enumerated). In addition, asynchronous and synchronous bit bang interface modes are available. The internally generated clock (6MHz, 12MHz and 24MHz) can be brought out on one of the CBUS pins to be used to drive a microprocessor or external logic.

The UMFT201XA is a module which is designed to plug into a standard 0.3” wide 16 pin DIP socket. All components used, including the FT201XQ are Pb-free (RoHS compliant).


The UMFT201XA utilises the FTDI FT201XQ; all the features of the FT201X can be utilized with the UMFT201XA. For a full list of the FT201X’s features please see the FT201X datasheet which can be found by clicking here. In addition to the features listed in the FT201X datasheet,

the UMFT201XA has the following features:

 Small PCB assembly module designed to fit a standard 7.62mm (0.3”) wide 16 pin DIP socket. Pins are on a 2.54mm (0.1”) pitch.

 On board USB ‘mini-B’ socket allows module to be connected to a PC or USB host via a standard A to mini-B USB cable.

 Functionally configurable using solder links. The default solder links setup enables the module to function without peripheral wires or application board. Other configurations enable external power supply options and variation of logic reference levels
