Table 8.1 Default Internal EEPROM Configuration
The internal EEPROM in the FT232R can be programmed over USB using the FTDI utility program MPROG.
MPROG can be downloaded from FTDI Utilities on the FTDI website (www.ftdichip.com). 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.
