... This determines the Baud Rate of the UART which is programmable from 300 baud to 2 million baud. For more details please contact FTDI. EEPROM Interface Though the FT8U232AM will work without the optional EEPROM, an external 93C46 EEPROM can be used to customise the USB VID, PID, Serial Number and Strings of the FT8U232AM for OEM applications. The EEPROM is also required for applications where multiple FT8U232AM’ ...
