מודול פיתוח USB 2.0 Hi-Speed to QuadSPI/I2C, FT4222H, VQFN-32

FT4222H evaluation module with D version chip.

The UMFT4222EV is a development module which uses FT4222H,

a Hi-speed USB2.0 to QuadSPI/I2C bridge in compact 32-pin QFN package.

The 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 128 bytes one-time-programmable (OTP) memory space for storing vendor specific information.

The FT4222H contains SPI/ I2C configurable interfaces.
