●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).

●• Asynchronous serial UART interface option with full hardware handshaking and modem interface signals.

●• Enhanced bit-bang Mode interface option with RD# and WR# strobes.

●• Configurable I/O drive strength.

●• Fully assisted hardware or X-On / X-Off software handshaking.

●• UART Interface supports 7/8 bit data, 1/2 stop bits, and Odd/Even/Mark/Space/No Parity.

●• Operational configuration mode and USB Description strings configurable in external EEPROM over the USB interface.

●• Low operating and USB suspend current.

●• Supports bus powered, self powered and high power bus powered USB configurations.

●• UHCI/OHCI/EHCI host controller compatible.

●• USB 2.0 Full Speed (12Mbits/Second) compatible.

●• Extended -40°C to 85°C industrial operating temperature range.

●• Compact 48-LD Lead Free LQFP package +4.35V to +5.25V single supply operating voltage range.

●• Dedicated Windows DLLs available for USB to JTAG, USB to SPI, and USB to I2C applications.

●• ESD protection for FT2232D IO‟s: Human Body Model (HBM) ±2kV, Machine Mode (MM) ±100V, Charge Device Model (CDM) ±500V, Latch-up free..
