Problems programming

[Lionheart]

I have found the problem after reading the datasheet throughly, i have found that this kind of pic is a one time programmeble.

They have a windowed version of this PIC that's erased with a UV light source similar to old EEPROMs, but it's pretty expensive.

If you prefer an 8-pin device, look at some of the newer flash-based parts like the 12Fxxx series. The 12F615 or 12F609 are very inexpensive, and easy to use.

[Lionheart]

It is indeed a good device but i don't see the type in Picbasic Pro, so can i program this device?

I have the chooce between:
12F508
12F509
12F629
12F675
12F683

The chips Bruce mentioned are in PBP 2.50.

The chips in your list are good too.
