The maximum cable length for the FT245BM is dependent on the baud rate and the quality of the cable. As a general rule, FTDI recommends a maximum cable length of 3 meters at 12 Mbps, 1.5 meters at 24 Mbps, and 0.5 meters at 48 Mbps.
The FT245BM is configured for asynchronous mode by default. To configure it for synchronous mode, you need to set the SYNCFF bit in the USB command register (0x08) to '1'. You can do this using the FTDI's MProg programming tool or through the D2XX driver.
The maximum power consumption of the FT245BM is 250 mA at 3.3V, which is the maximum current that the device can draw from the USB bus.
Yes, the FT245BM is 5V tolerant, but it is recommended to use a level shifter or a voltage regulator to ensure that the voltage levels are within the recommended operating range of 3.3V ± 0.3V.
The FT245BM supports RTS/CTS flow control. You can implement flow control by connecting the RTS (Request to Send) output to the CTS (Clear to Send) input of the external device, and vice versa. You can also use software flow control using the XON/XOFF protocol.
