For a full list of the FT221Xs circuit devices. FT221X is a USB to SPI/FT1248 features please see the FT221X datasheet which interface with a battery charger detection feature, can be found by clicking here. which can allow batteries to be charged with a higher current from a dedicated charger port In addition to the features listed in the FT221X (without the FT221X being enumerated). In datasheet, the UMFT221XE has the following addition, asynchronous and synchronous bit bang features: interface modes are available. The internally generated clock (6MHz, 12MHz and 24MHz) can Small PCB assembly module designed to fit a be brought out on the CBUS pin to be used to standard 15.24mm (0.6) wide 20 pin DIP drive a microprocessor or external logic. socket. Pins are on a 2.54mm (0.1) pitch. The UMFT221XE is a module which is designed to On board USB mini-B socket allows module plug into a standard 0.6 wide 20 pin DIP socket. to be connected to a PC via a standard A to All components used, including the FT221XQ are mini-B USB cable. Pb-free (RoHS compliant). Functionally configurable using jumpers. 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.
