10. 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 values programmed into the internal EEPROM in a brand new device are defined
in Table 18.
Table 18 - Default Internal EEPROM Configuration
Parameter
Value
Notes
USB Vendor ID (VID)
0403h
FTDI default VID (hex)
USB Product ID (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 the power is shut off (PWREN# is high)
Manufacturer Name
FTDI
Manufacturer ID
FT
Serial number prefix
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 descriptor to the host. Note: The device is be
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.
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.
CBUS4
SLEEP#
Default configuration of CBUS4 - Low during USB suspend.
Invert TXD
Disabled
Signal on this pin becomes TXD# if enabled.
Invert RXD
Disabled
Signal on this pin becomes RXD# if enabled.
Invert RTS#
Disabled
Signal on this pin becomes RTS if enabled.
Invert CTS#
Disabled
Signal on this pin becomes CTS if enabled.
Invert DTR#
Disabled
Signal on this pin becomes DTR if enabled.
Invert DSR#
Disabled
Signal on this pin becomes DSR if enabled.
Invert DCD#
Disabled
Signal on this pin becomes DCD if enabled.
Invert RI#
Disabled
Signal on this pin becomes RI if enabled.
The internal EEPROM in the FT232R can be programmed over USB using the utility program MPROG. MPROG can
be downloaded from the
FTDI website
. Version 2.8a or later is required for the FT232R 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.
