So I can say 9v.

Some device of HC'9'08 can be found as Vdd+4.5v as the maximum rating, those should be far from problem to the modification of 9volts++

Here is help from one not low cost programming tool ;-)
So maybe they do wrong too ...

Also here is original data from HC08AZ32 datasheet.
So if Vdd = 5V ( oas you say 4.5V ) but never 4V ...
Motorola give IRQ = Vdd + VHI ( where we all know to HI level is Vdd ) so VHI must be from 4.5V to 5V which give IRQ = 9.5V-10V but we can usage 9 without problem cos 4V as VHI is also high logic level 100%.
But we cant say to 8V is good value as is in blue PCB so ...

Here is part from original HC08AZ32 datasheet:

I did not say Vdd 4.5v, to mark out Vddx2 of 9v. No Vddx2 story in HC08 literatures but always refered as Vdd + something.

I disagree to hold Vpp at 8v neither and 100% agree to this modification. Ive made major modifications on my blue board too as well as a successful test on 'HC05 security adapter not writing problem'. Just pointing out that the setting Vpp to or close to 10v may break over some HC08 device IRQ maximum rating.

In the more up-to-date original Motorola HC08 documents, IRQ (and not as IRQ1 from the 1997 doc.) maximum IRQ voltage always presents in Maximum Ratings table as below samples e.g. HC08AZ32, AZ60 and AS60 at Vdd+4v and some other at Vdd+4.5v.

Happy modifying

one question where i can buy an good xprog-m clone i read so much my head is smoking.

So we now on same way....
If you have some interest MOD too please to post.
Then we all can end story about bad china clone of XprogM.

My best regard's to all

Wrong reading of resistor , it is 182 = 1k8 !
It is rotated 180 degree in soldering process...
With 280 ohm you will read on IRQ 16V " DANGER " .
On standard LM317 circuit it is recommended to be 270 ohm but here is different....
So with 1k5 + 100 ohm connected in series on his place it will be UNLOADED exact 9.85V and with load 9.5V which is perfect.

Yes indeed I was braindead. Sorry.
Thank you.

A lot of problems with the clone Xprog-M due to the application rejected, cheap components.
We need to change atmega64 to normal.
Search for a dump ...

Hi elchip,

After you modified that resistor , is there any side effect for other mpu except hcxx??

change to dumps for mpps 3.0.2.37

Guys check this link.They sells a lot of programmers that works fine.They price is cheeper than Chinese.WBR.???-Prog-M - ????? ?????+????? = 140$ ? ????????? - ????????????? ?????? Oktja.ru

I have clone V5.0 X-prog-m programmer.
I try to read ST10F269. Every time stops at 16% or 19%.
Any tips ?

Thanks in advance.

now, x-progm clone only US $88
China clone, russia clone, etc clone, xyz clone are the same.

The important thing is how we use it with the support of science and the right trick
