Clearance No.: FTDI# 39

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

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).

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.
