UMFT4222EV-D

UMFT4222EV-D is a FT4222H evaluation module with D version chip. The UMFT4222EV is a development module which uses FTDI’s FT4222H, a Hi-speed USB2.0 to Quad SPI/I2C Bridge in compact 32-pin QFN package. FT4222H requires an external crystal (12MHz) for the internal PLL to operate. It supports multi-voltage IO, 3.3V, 2.5V or 1.8V. It also provides 128bytes 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 host mode with single, dual, or quad bits data width transfer or server mode with single bit data width transfer. The I2C interface can be configured as host or server mode. The UMFT4222EV is supplied as a small PCB which is designed to plug into a standard 0.8” wide 24 pin DIP socket.
