PIC16F627A Upgrade...?

[tlambertsen]

HI.

Thanks for a great forum, very useful information to be found.

Have a quick first question

I have up untill now used the 16f627a for my projects, But for my latest project I have run out of I/O pins. What would be a good "next step up"

I have looked at the pic18F2220, as I can source that easily

any suggestions.

Spec.
Serial pc interface (Rs232)
17 general purpose I/O pins for LEDs, and switches

Best regards

An obvious upgrade from the 16F627 would be something like a 16F877, and an upgrade from that an 18F series - but if you wanted to jump direct to the
18F series that would be fine as well.

If you want to stay with the 16 series then I would suggest the 16F886 (28 pin) or 887 (40 pin) as these have an internal oscillator whereas the 876 and 877 don't.

Thanks for the quick reply and the help

Will try the 16F886 as component numbers must be kept down.

Thanks

Lower part numbers are better?

Go for the 18F series (the 18F1320 and 18F2220 are fine upgrades)

I hate going back to 16F having spent so much time working with the 18F

 

[blueroomelectronics]

The 18F are not much more expensive than their equivalent 16F counterpart. They are better in just about every aspect.
