Following a power-on reset or a USB reset the FT232H will scan its internal EEPROM and read the USB
configuration descriptors stored there. The default values programmed into the external EEPROM for the
FT232H used on the UM232H-B are shown in Table 8.1.

The on board EEPROM can be programmed over USB using the utility program FT_PROG. FT_PROG can
be downloaded from the www.ftdichip.com. 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.

Notes
FTDI default VID (hex)
FTDI default PID (hex)
A unique serial number is generated and programmed into
the EEPROM during final test of the UM232H-B module.
Enabling this option will make the device pull down on the
UART interface lines when the power is shut off (PWREN#
is high).
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).
Taking RI# low will wake up the USB host controller from
suspend.
Enables the high drive level on the UART and CBUS I/O
pins.
Makes the device load the CVP driver interface for the
device.

Power Enable, low when FT232H enumerates, switches 5V
output power on when the device enumerates.
Power Enable, low when the FT232H enumerates, ,
switches the on board LED on when the device enumerates.
Signal on this pin becomes TXD# if enable.
