9 Internal EEPROM Configuration
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.
Parameter
Value
Notes
USB Vendor ID (VID)
0403h
FTDI default VID (hex)
USB Product UD (PID)
6001h
FTDI default PID (hex)
Serial Number Enabled?
Yes
Serial Number
See Note
A unique serial number is generated and
programmed into the EEPROM during device final
test.
Pull down I/O Pins in USB
Suspend
Disabled
Enabling this option will make the device pull down
on the FIFO interface lines when in USB suspend
mode (PWREN# is high).
Manufacturer Name
FTDI
Product Description
FT245R USB FIFO
Max Bus Power Current
90mA
Power Source
Bus Powered
Device Type
FT245R
USB Version
0200
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).
Remote Wake Up
Enabled
Taking RXF# low will wake up the USB host
controller from suspend in approximately 20 ms.
High Current I/Os
Disabled
Enables the high drive level on the FIFO data bus
and control I/O pins.
Load VCP Driver
Enabled
Makes the device load the VCP driver interface for
the device.
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.
