1.1 Driver Support

The FT2232H requires USB drivers (listed below) , available free from

http://www.ftdichip.com,

which

are used to make the FT2232H appear as a virtual COM port (VCP). This 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 FT2232H

through a DLL.

Package

FT2232HL-xxxx

FT2232HQ-xxxx

Note: Packaging code for xxxx is:

64 Pin LQFP

64 Pin QFN

- Reel: Taped and Reel (LQFP =1000 pcs per reel, QFN =4000 pcs per reel)

-Tray: Tray packing, (LQFP =160 pcs per tray, QFN =260 pcs per tray)

Please refer to section 8 for all package mechanical parameters.

1.3 USB Compliant

The FT2232H is fully compliant with the USB 2.0 specification and has been given the USB-IF Test-ID

(TID) 40720019.

The timing of the rise/fall time of the USB signals is not only dependant on the USB signal drivers, it is

also dependant system and is affected by factors such as PCB layout, external components and any

transient protection present on the USB signals. For USB compliance these may require a slight

adjustment. This timing can be modified through a programmable setting stored in the same external

EEPROM that is used for the USB descriptors. Timing can also be changed by adding appropriate passive

components to the USB signals.
