This then allows the user to communicate with the USB interface via a standard PC serial emulation port (for example TTY). Another FTDI USB driver, the D2XX driver, can also be used with application software to directly access the FT2232D though a DLL. Royalty free VIRTUAL COM PORT (VCP) DRIVERS for...

Common pins are defined in the first section, and then the I/O pins are defined by chip mode. Note: The convention used throughout this document for active low signals is the signal name followed by# 3.2 Common Pins The operation of the following FT2232D pins do not change regardless of the configured mode:Pin No. Name Type Description 7 USBDP I/O USB Data Signal Plus ( Requires 1.5K pull-up to 3V3OUT or RSTOUT# ) 8 USBDM I/O USB Data Signal Minus Table 3.1.1 USB Interface Group Pin No. 48 Name Type EECS I/O EESK OUTPUT Description EEPROM – Chip Select. Tri-State during device reset. **Note 1 Clock signal to EEPROM. Tri-State during device reset, else drives out. **Note 1 EEDATA I/O EEPROM – Data I/O Connect directly to Data-In of the EEPROM and to Data-Out of the EEPROM via a 2.2K resistor. Also, pull Data-Out of the 2 EEPROM to VCC via a 10K resistor for correct operation. Tri-State during device reset. **Note 1 Table 3.2.2 EEPROM Interface Group 1 Pin No. Name Type 4 RESET# INPUT Description Can be used by an external device to reset the FT2232D. If not required, tie to VCC. **Note 1 5 RSTOUT# OUTPUT Output of the internal Reset Generator. Drives low for 5.6 ms after VCC > 3.5V and the internal clock starts up, then clamps it‟s output to the 3.3V output of the internal regulator. Taking RESET# low will also force RSTOUT# to drive low. RSTOUT# is NOT affected by a USB Bus Reset. 47 TEST INPUT Puts device into I.C. test mode – must be tied to GND for normal operation. 41 PWREN# OUTPUT Goes Low after the device is configured via USB, then high during USB suspend. Can be used to control power to external logic using a PChannel Logic Level MOSFET switch. Enable the Interface Pull-Down Option in EEPROM when using the PWREN# pin in this way. 43 XTIN INPUT Input to 6MHz Crystal Oscillator Cell. This pin can also be driven by an external 6MHz clock if required. Note: Switching threshold of this pin is VCC/2, so if driving from an external source, the source must be driving at 5V CMOS level or a.c. coupled to centre around VCC/2. 44 XTOUT OUTPUT Output from 6MHz Crystal Oscillator Cell. XTOUT stops oscillating during USB suspend, so take care if using this signal to clock external logic. Table 3.3.3 Miscellaneous Signal Group **Note 1 - During device reset, these pins are tri-state but pulled up to VCC via internal 200K resistors.
