EEPROM interface. Though the FT232B will work without the optional EEPROM, an external 93C46  
(93C56 or 93C66) EEPROM can be used to customise the USB VID, PID, Serial Number, Product  
Description Strings and Power Descriptor value of the FT232B for OEM applications. Other parameters  
controlled by the EEPROM include Remote Wake Up, Soft Pull Down on Power-Off and USB 2.0 descriptor  
modes. The EEPROM should be a 16 bit wide configuration such as a MicroChip 93LC46B or equivalent  
capable of a 1Mb/s clock rate at VCC = 4.35V to 5.25V. The EEPROM is programmable-on board over  
USB using a utility available from FTDI’s web site (http://www.ftdichip.com). This allows a blank part to be  
soldered onto the PCB and programmed as part of the manufacturing and test process. If no EEPROM is  
connected (or the EEPROM is blank), the FT232B will use its built-in default VID, PID Product Description  
and Power Descriptor Value. In this case, the device will not have a serial number as part of the USB  
descriptor.
