Description

The UMFT4222EV is a development module which uses FTDI’s FT4222H, a Hi-Speed USB2.0 to QuadSPI/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 128 Bytes one-time-programmable

(OTP) memory space for storing vendor specific information. The FT4222H contains SPI/ I

2C 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 I

2C 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).
