8 Internal EEPROM Configuration
Following a power-on reset or a USB reset the FT232R 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 8.1.
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 UART interface lines when in USB suspend
mode (PWREN# is high).
Manufacturer Name
FTDI
Product Description
FT232R USB UART
Max Bus Power Current
90mA
Power Source
Bus Powered
Device Type
FT232R
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 RI# 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 UART and CBUS
I/O pins.
Load VCP Driver
Enabled
Makes the device load the VCP driver interface for
the device.
CBUS0
TXLED#
Default configuration of CBUS0 – Transmit LED
drive.
CBUS1
RXLED#
Default configuration of CBUS1 – Receive LED drive.
CBUS2
TXDEN
Default configuration of CBUS2 – Transmit data
enable for RS485
CBUS3
PWREN#
Default configuration of CBUS3 – Power enable. Low
after USB enumeration, high during USB suspend
mode.
