Hello Geethanjali,

- FX2LP18 can work with the same firmware as long as you are using C2 boot load method. FX2LP18 does not support C0 load/No EEPROM load method of firmware download.

- Please refer to the below App Note for other differences between FX2LP and FX2LP18 in terms of hardware.

FX2LP18  doesnot support No eeprom load means "it doesnot  support RAM firmware programming " right?

please let me know.

Hello Geethanjali,

By default, it does not support RAM programming method. A one line code to clear the DISCON and RENUM bits can be loaded into the EEPROM. This will connect the device to the host and indicate that the default USB device handles the requests. After this is successful, a new firmware can be loaded into the FX2LP18 RAM using the Control Center.
