X-Prog M

Look on motorola datasheet all motorola MCU for IRQ usage Vdd X 2 ...
So no place in datasheet precise Vpp on IRQ pin !
Cos some devices work on 5V Vdd and need 10V Vpp , and devices which usage 3.3V need 6.6V on IRQ..
So you cant say 9V ...
Simple is Vpp ( IRQ ) = Vdd X 2 that all.

And I know to XprogM cant do security HC05B16 cos it need full different configuration like in ETL to go to bootstrap special mode jump to desired address etc etc ...
But it is different story ...

Here we go...
For all DK members for free how to fix XprogM blue PCB problem
if it not work good HC05 and HC705 MCU.
First measure IRQ when you hit read or write to see if mod need and if need here is picture how do that...
Start with 1K5 and measure IRQ voltage without HC05 adapter just hit READ and measure if voltage is little bigger
example 10.4V then you need 1k5 + 100 ohm in serie to get 1k6 and again measure...
When you measure from 9.5 V to maximum 10V you is in range.
Usual XprogM usage VppR for IRQ - that is Vpp from LM317 via 4K7 internal resistor.
So you can easy measure Vpp in programing progress .So Vpp will be little highter then VppR cos VppR drop voltage on 4k7 resistor about 50 mV or so ...
If you measure Vpp = 9.75V VppR will be about 9.17V...

I cant find on any HC08 datasheet say the Vpp on IRQ pin being 'Vddx2' neither ! But mostly the instructions are the IRQ input voltage of Vdd+4V as maximum rating.

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

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
