UCD90120: UCD90120 NVRAM programming with EVM

Abhijit Khadilkar

Part Number: UCD90120
Other Parts Discussed in Thread: UCD90SEQ64EVM-650,

Hi,

I am using the UCD90SEQ64EVM-650 EVM to program the UCD90120 parts. The programmed parts will be sent for component assembly on to the board. On the EVM while programming it is detecting address as 101d.

I am programming the device in NVRAM with a file having address 66d. This will be the address on the soldered board.

Question: The programming file is having address 66d. Will the device work on the soldered board, if it is detected as address 101d on EVM while programming and address on the soldered board will be 66d?

thanks, Abhijit

If you are using Fusion GUI to program, GUI will use the address from the target device to program

Hi, Abhijit,

Program UCD90XX devices will not change device's address. Device on soldered board will come up with whatever PMBus Address setting on the soldered board. See section 7.4.22 (PMBus Address selection) in Datasheet for more detail.
