I need help reading hc11e1 5C91F chip in renault , i removed chip and tried reading without success xprog-m and etl .

Do i need to solder back to do this or off board since i desoldered already. If you have a pix, it will be appreciated
Is this with xprog-m?

Hi,mates.Find MCU in sw menus with the same configuration and try again.I think that is the same as most HC11E9.Look this.Regards.

I successfully programmed this mcu using upa serial as 68hc11e9

[sogaro]

I have UPA too but am always scared stiff to use it as have heard it can destroy chips. Can you assist me further with details, a live pix would be most welcome

[dimitar]

I used this connection

[sogaro]

Thanks but this is xprog-t and not UPA, i have it too, the old version on Win98 and will try in the morning, should i solder back to read it?

Sogaro if you are using X-progM try to read it as secure chip (don't worry about the mask).

I tried this and for about 15 minutes , the green light kept flashing so i disconnected it. will try to clean the pins and retry

@taiwo
update your X rpog M to 5.0

I read that kind of MCU with upa-usb using quartz from 4MHz to 20MHz (I was testing a little), while xprog-m requires 8MHz quartz. Using other resonator values I was unable to read it.
Regarding this kind of MCU, upa-usb seems to be more flexible...

DONE at last, you guys are wonderful. I eventually read dump with XPROG-T without stress...............just simply done.

No stress at all 68hc11e1 is mask rom contains only eprom nothing else neither it has a security option

Hi pal for the record, i can always make it work using some crystal of 4mhz and in paralell with i some 10Mohm resistor. and works wonderfull.
