Following a power-on reset or a USB reset the FT245R will scan its internal EEPROM and read the USB
configuration descriptors stored there. The default factory programmed values of the internal EEPROM
are shown in Table 9.1 Default Internal EEPROM Configuration.

The internal EEPROM in the FT245R can be programmed over USB using the FTDI utility program MPROG
and FT_PROG which can be downloaded from FTDI Utilities, on the FTDI website (www.ftdichip.com).
Version 2.8a or later is required for the FT245R chip. Users who do not have their own USB Vendor ID
but who would like to use a unique Product ID in their design can apply to FTDI for a free block of unique
PIDs. Contact FTDI support for this service.

Notes
FTDI default VID (hex)
FTDI default PID (hex)
A unique serial number is generated and
programmed into the EEPROM during device final
test.
Enabling this option will make the device pull down
on the FIFO interface lines when in USB suspend
mode (PWREN# is high).
Returns USB 2.0 device description to the host.
Note: The device is a USB 2.0 Full Speed device
(12Mb/s) as opposed to a USB 2.0 High Speed
device (480Mb/s).
Taking RXF# low will wake up the USB host
controller from suspend in approximately 20 ms.
Enables the high drive level on the FIFO data bus
and control I/O pins.
Makes the device load the VCP driver interface for
the device.
