UMFT240XA Datasheet Version 1.3 Document Reference No.: FT 000520 Clearance No.: FTDI 271 Future Technology Devices International Datasheet UMFT240XA USB to 8-bit 245 FIFO Development Module UMFT240XA is a USB to 8-bit 245 FIFO DIP module with a 0.3 row pitch. 1.1 Features 1 Introduction The UMFT240XA is a development module for The UMFT240XA is fitted with a FT240XQ, all the FTDIs FT240XQ, one of the devices from FTDIs features of the FT240X can be utilized with the range of USB to serial data interface integrated UMFT240XA. For a full list of the FT240Xs features circuit devices. FT240X is a USB to 245 FIFO please see the FT240X datasheet which can be found interface with a battery charging feature, which at the FTDI website. can allow batteries to be charged with a higher In addition to the features listed in the FT240X current from a dedicated charger port (without the datasheet, the UMFT240XA has the following FT240X being enumerated). In addition, features: asynchronous and synchronous bit bang interface modes are available. The internally generated clock Small PCB assembly module designed to fit a (6MHz, 12MHz, 24MHz and 48MHz) can be brought standard 7.62mm (0.3) wide 24 pin DIP socket. out of the on one of the CBUS pin to be used to Pins are on a 2.54mm (0.1) pitch. drive a microprocessor or external logic. On board USB mini-B socket allows module to The UMFT240XA is a module which is designed to be connected to a PC via a standard A to mini-B plug into a standard 0.3 wide 24 pin DIP socket. USB cable. All components used, including the FT240XQ are Pb-free (RoHS compliant). 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.
