1.2 General Description
The DLP-2232M-G module is a USB interface that incorporates the functionality of two
DLP-USB2xxM modules into a single 40-pin module. A single downstream USB port is
converted to two IO channels that can each be individually configured as a DLP-
USB232M-style UART interface, or a DLP-USB245M-style FIFO interface, without the
need to add a USB hub.
There are also several new modes which can be enabled in the external EEPROM, or by
using DLL driver commands. These include Synchronous Bit-Bang Mode, a CPU-Style
FIFO Interface Mode, a Multi-Protocol Synchronous Serial Engine Interface Mode, MCU
Host Bus Emulation Mode, and Fast Opto-Isolated Serial Interface Mode. Additionally,
a new high output drive level option means that the device UART / FIFO IO pins will
drive out at around three times the normal power level, allowing the data bus to be shared
by several devices.
Classic BM-style Asynchronous Bit-Bang Mode is also supported, but has been enhanced
to give the user access to the device’s internal RD# and WR# strobes.
FTDI provides a royalty free Virtual Com Port (VCP) driver that makes the peripheral
ports look like a standard COM port to the PC. Most existing software applications
should be able interface with the Virtual Com Port simply by reconfiguring them to use
the new ports created by the driver. Using the VCP drivers, an application programmer
would communicate with the device in exactly the same way as they would a regular PC
COM port - using the Windows VCOMM API calls or a COM port library.
The FT2232D driver also incorporates the functions defined for FTDI’s D2XX drivers,
allowing applications programmers to interface software directly to the device using a
Windows DLL.
