Will the external ROM be programmed through the USB after assembly?

Latest Updated:06/01/2006

Question:

For the USB hub controller, can the external serial ROM be programmed after assembly?

Answer:

uPD720110A does not have function to program external serial ROM for configuration. It must be programmed before board assembly or programmed by other circuit on the board.
uPD720112 and uPD720113 have capability of programming external serial ROM through upstream port. The programming tool is available for both DOS and Windows.
