... GENERAL DESCRIPTION The DLP-USB245M provides an easy cost-effective method of transferring data to / from a peripheral and a host Million bits (1-Megabyte) per second. Its simple FIFO-like design makes it easy to interface to any microcontroller or microprocessor via IO ports. To send data from the peripheral to the host computer simply write the byte wide data into the module when TXE# is low ...

... Unzip the file to a blank floppy disk or folder on your PC. The drivers can co-exist on the same floppy disk or folder since the INF files determine which set of drivers to load for each operating system version. Once loaded, the VCP drivers allow your application software, running on the host PC, to communicate with the DLP-USB245M as though it were connected to a COM (RS-232) port. ...

... Download the serializer program from either dlpdesign.com or ftdichip.com. Unzip the package and place folder on the hard drive. 3. Select a power source for the DLP-USB245M module via pins 10, 11, and 12. Be sure to pull the RESET# pin high (pin 3). 4. Connect the DLP-USB245M board to the PC via a standard, 6-foot USB cable. This action initiates the loading of the USB drivers. When prompted, select the folder where the DLL version of the device drivers were stored Copyright © ...

... Terminate the serializer program and disconnect the DLP-USB245M board from the USB cable. Wait 10 seconds and reconnect the DLP-USB245M board. Reboot the PC if instructed to do so. NOTE 1 - The DLP-USB245M comes pre-programmed with a default VID and PID. Step 5 is optional and only required if different VID/PID codes are required. ...

High for DLP- USB232M and low for DLP-USB245M. 2 Ground 3 RESET# (In) Can be used by an external device to reset the FT245BM. If not required this pin must be tied to VCC. 4 RESETO# (Out) Output of the internal Reset Generator. Stays high impedance for ~ 2ms after VCC > ...

... SND/WUP (In) If the DLP-USB245M is in USB suspend, a positive edge on this pin (WAKEUP) initiates a remote wakeup sequence. If the device is active (not in suspend) a positive edge on this pin (SEND) causes the data in the write buffer to be sent to the PC on the next USB Data-In request regardless of how many bytes are in the buffer ...

... Figure 3 3.3V Figure 3 shows how to configure the DLP-USB245M to interface with a 3.3v logic device. In this example, the target electronics provides the 3.3 volts via the VCCIO line (pin 10) which in turn will cause the FIFO interface IO pins to drive out at 3.3v level. Bus Powered Circuit with Power Control USB Bus powered circuits need to be able to power down in USB suspend mode in order to meet the < ...
