DS90UH927Q-Q1: How to tell the difference between UH and UB

Part Number: DS90UH927Q-Q1

Hi Team,

If I do not have access to visually see the topside marking of the DS90Ux927-Q1 device, is there a register I can read or some sort of indication that the device is either a UH927 or UB927?

Thank you!

Jared

    Hello Jared,

    Registers 0xF0-0xF5 spell out "_Ux927" in ASCII hex codes where the "x" is either B or H depending on the device variant, so you can read just register 0xF2 and for the UB version it will return 0x42. For the UH version it will return 0x48

    Best Regards,
    Casey
