The UMFT221XE-01 is an USB to 8-bit SPI Development Module with a 0.6-inch row pitch. It is suitable for FT221XQ USB to serial data interface integrated circuit device. It is an 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 FT221X being enumerated). In addition, asynchronous and synchronous bit bang interface modes are available. The internally generated clock (6, 12 and 24MHz) can be brought out on one of the CBUS pins to be used to drive a microprocessor or external logic. It is designed to plug into a standard 0.6-inch wide 16-pin DIP socket.
