[FTDI]

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..
