UMFT4222EV Development Module


FTDI's UMFT4222EV is a development module which uses their FT4222H, a hi-speed USB 2.0 to QuadSPI/I²C bridge in a compact 32-pin QFN package. The FT4222H requires an external crystal (12MHz) for the internal PLL to operate. It supports multi-voltage IO, 3.3 V, 2.5 V, or 1.8 V. It also provides 128-bytes one-time-programmable (OTP) memory space for storing vendor-specific information. The FT4222H contains SPI/I²C configurable interfaces. The SPI interface can be configured as master mode with single, dual, or quad bits data width transfer or slave mode with single bit data width transfer. The I²C interface can be configured as master or slave mode. The UMFT4222EV is supplied as a small PCB which is designed to plug into a standard 0.8” wide 24-pin DIP socket. All components are Pb-free (RoHS compliant).
