Hello, I am looking for information on the layout Nuvoton about the designation NPCE586HA2MX. The main question is whether this system is programmable? I know it's mounted on boards DA0X8CMB6E0 REV E I found it on the CD DA0X81MB6E0 Rev E , but ending with DA0X8CMB 0MX . Are these chips...

It is about Nuvotn kbc npce586ha0mx qfp-128 on HP ProBook 450 G3/ HP ProBook 470 G5 board from Quanta DAX63CMB6C0 Rev:C There is SM and *boardview Compare pins in HP ProBook 455 G4 (Quanta x93A/ DAX93AMB6G0 ) there is NPCE586H There is SM and *brdv link ps on (ebay) for a lot(5x) of about $8 NPCE586HA2MX NPCE586HA0MX NPCE586HAOMX NPCE586HAZMX > 586 I/O series

The system is programmed in the production process, it does not require programming with a programmer after replacing the system.

So it follows that you need to look for a donor (NPCE586HA2MX) from Donora!

@lisek I'm sorry that I am calling you to a topic in which you may not have wanted to participate, but you are one of the few people on this forum who have such familiar occurrence of KBC systems on motherboards. If you can help me, I will be obliged. This is what I found on the discs: DA0X8BMB6F0 DA0X8BMB6G0 DAX8BCMB8D1 There is no schematic or boardview for any of the boards mentioned. Can anyone help with pinout?

Thanks so much for the very useful information. The block diagram of the X8C, X93A, and X81 boards shows KBC NPCE586HA0MX, while the X63C shows as NPCE586H and they have identical pins. I wonder how the NPCE586HA0MX differs from the NPCE586HA2MX, because nowhere in the block I have not found the full designation of this model, which interests me.

The manufacturer Nuvoton probably knows about the difference ? maybe try to write to them > what's the difference

A program uploaded by the manufacturer that defines, among other things, the functions of individual pins and a few other things.

Hello,
I am looking for information on the layout Nuvoton about the designation NPCE586HA2MX.
The main question is whether this system is programmable?
I know it's mounted on boards DA0X8CMB6E0 REV E I found it on the CD DA0X81MB6E0 Rev E , but ending with DA0X8CMB 0MX .
Are these chips interchangeable?
What motherboards are they on?
Can these chips on one board have a different pinout than on another?
If anyone, I'll ask you something
Regards
Jack
