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.

Serial Number
See Note
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 UART interface lines when in USB suspend
mode (PWREN# is high).

Returns USB 2.0 device description to the host.
USB Version
0200
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 RI# low will wake up the USB host controller
from suspend in approximately 20 ms.
Enables the high drive level on the UART and CBUS
I/O pins.
Makes the device load the VCP driver interface for
the device.
Default configuration of CBUS0 – Transmit LED
drive.
Default configuration of CBUS1 – Receive LED drive.
Default configuration of CBUS2 – Transmit data
enable for RS485
Default configuration of CBUS3 – Power enable. Low
after USB enumeration, high during USB suspend
mode.
