18F8722 INC and BAS

[George]

I ordered some 18F8720, the supplier didn't have any and gave me the 8722 instead, just looking, I have PBP2.42 and it doesn't have the 8722 listed, just the 8720. Does anyone know where I can get them from? Can I just make a new file from the 8720 and rename it?

Cheers in advance

Looks like it is past time for you to up grade.
It is in the newer versions.

The PIC18F8720 had problems running above 4Mhz, but only in certain situations. It's all in the errata sheets.
The '8722 is it's "replacement". Does the same job, with enhancements...

skimask, I use 18F8720's for my depth and temperature display unit and have had no problems running them above 4 Mhz. I run them at 24 Mhz. as they will not run at 40.

You can just rename the files and your '8720 program will run in an '8722.

The errata sheet doesn't say the '8720 fails under ALL conditions above 4Mhz. It just says 'under certain circumstances'. Apparently, I was able to fullfill those 'circumstances' in one of my projects and make it die at 10Mhz, but ran just fine at 4Mhz. Switched to the '8722, no problems.
