UMFT4222EV-C

The UMFT4222EV-C from FTDI is a FT4222H evaluation module with C version chip. This module uses FTDI's FT4222H, a hi-speed USB2.0 to QuadSPI/I2C bridge in compact 32-pin QFN package. FT4222H requires an external crystal for internal PLL to operate. It supports multi-voltage IO, 3.3V, 2.5V or 1.8V. It provides 128byte 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. I2C interface support 7bit address and fully compatible to v2.1 and v3 specification for I2C master/slave mode with configurable target operating speed for 100Kbps standard mode, 400Kbps fast mode 1Mbps fast mode plus and 3.4Mbps high speed mode. It is supplied as small PCB which is designed to plug into standard 0.8" wide 24 pin DIP socket. On board USB micro-B receptacle allows module to be connected to PC.
