The FT2232D is a dual USB to serial UART or FIFO interface with the following advanced

features:

Single chip USB to dual channel serial / parallel ports with a variety of configurations.

Entire USB protocol handled on the chip.

No USB specific firmware programming required.

Transfer Data Rate 300 to 3 Mbaud.

USB to parallel FIFO transfer data rate up to 1 megabyte / second.

Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous serial

protocol (USB to JTAG, USB to I2C, USB to SPI) design.

CPU-style FIFO interface mode simplifies CPU interface design.

MCU host bus emulation mode configuration option.

Fast Opto-Isolated serial interface option.

FTDI‟s royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.

Highly integrated design includes 3.3V LDO regulator for USB I/O, integrated POR function

and on chip clock multiplier PLL (6MHz –48MHz).
