The UMFT4222EV is an USB2.0 to QuadSPI/I2C Bridge Development Module, uses FTDI's FT4222H. FT4222H requires an external crystal (12MHz) for the internal PLL to operate. It supports multi-voltage IO, 3.3, 2.5 or 1.8V. 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-inch wide 24-pin DIP socket. OTP memory inside for USB vendor ID (VID), product ID (PID), device serial number, product description string and various other vendor specific data.
