UMFT231XE Version 1.0 Document Reference No.: FT 000652 Clearance No.: FTDI 294 Future Technology Devices International Ltd Datasheet UMFT231XE USB to Full- Handshake UART Development Module UMFT231XE is a USB to serial Full-Handshake UART DIP module with a 0.6 row pitch. 1.1 Features 1 Introduction The UMFT231XE is a development module The UMFT231XE is fitted with a FT231XQ, for FTDIs FT231XQ, one of the devices all the features of the FT231X can be from FTDIs range of USB interface bridging utilized with the UMFT231XE. For a full list integrated circuit devices. FT231X is a USB of the FT231Xs features please see the to UART interface with a battery charger FT231X datasheet which can be found by detection feature, which can allow batteries clicking here. to be charged with a higher current from a In addition to the features listed in the dedicated charger port (without the FT231X datasheet, the UMFT231XE has the FT231X being enumerated). In addition, following features: asynchronous and synchronous bit bang interface modes are available. The Small PCB assembly module designed to internally generated clock (6MHz, 12MHz fit a standard 15.24mm (0.6) wide 20 and 24MHz) can be brought out of the on pin DIP socket. Pins are on a 2.54mm one of the CBUS pin to be used to drive a (0.1) pitch. microprocessor or external logic. On board USB mini-B socket allows The UMFT231XE is a module which is module to be connected to a PC via a designed to plug into a standard 0.6 wide standard A to mini-B USB cable. 20 pin DIP socket. All components used, including the FT231XQ are Pb-free (RoHS Functionally configurable using jumpers. compliant). The default jumper 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. Use of FTDI devices in life support and/or safety applications is entirely at the users risk, and the user agrees to defend, indemnify and hold harmless FTDI from any and all damages, claims, suits or expense resulting from such use.
