UMFT220XA Datasheet Version 1.4 Document Reference No.: FT 000517 Clearance No.: FTDI 267 Future Technology Devices International Datasheet UMFT220XA USB to 4-bit SPI/FT1248 Development Module UMFT220XA is a USB to 4-bit SPI/FT1248 DIP module with a 0.3 row pitch. 1.1 Features 1 Introduction The UMFT220XA is a development module for The UMFT220XA is fitted with a FT220XQ all the FTDIs FT220XQ, one of the devices from FTDIs features of the FT220X can be utilized with the range of USB interface bridging integrated circuit UMFT220XA. For a full list of the FT220Xs features devices. FT220X is a USB to 4-bit SPI/FT1248 please see the FT220X datasheet which can be found (only up to 4 bit wide) interface with a battery by clicking here. charger detection feature, which can allow In addition to the features listed in the FT220X batteries to be charged with a higher current datasheet, the UMFT220XA has the following features: from a dedicated charger port (without the FT220X being enumerated). In addition, Small PCB assembly module designed to fit a asynchronous and synchronous bit bang interface standard 7.62mm (0.3) wide 16 pin DIP socket. modes are available. The internally generated Pins are on a 2.54mm (0.1) pitch. clock (6MHz, 12MHz and 24MHz) can be brought out on the CBUS pin to be used to drive a On board USB mini-B socket allows module to be microprocessor or external logic. connected to a PC via a standard A to mini-B USB cable. The UMFT220XA is a module which is designed to plug into a standard 0.3 wide 16 pin DIP socket. Functionally configurable using solder links. The All components used, including the FT220XQ are default solder links setup enables the module to Pb-free (RoHS compliant). function without peripheral wires or application board. Other configurations enable external power supply options and variation of logic reference levels.
