I need to debug a 16F627a Microcontroller. I already bought a kit150 and an icd-u40, but I dont know if these are even compatible. Can someone tell me what I need to buy to get the chip debugged?

According to this chart on the CCS website, you need a special -ICD chip
to debug code for the 16F627A.
http://www.ccsinfo.com/devices.php?page=icddevices

According to page 5 of this Microchip document, the chip you need
is a 16F648A-ICD. On page 1 of the same document, this special
chip is available on a header with this part number: AC162053 http://ww1.microchip.com/downloads/en/DeviceDoc/51292J.pdf

If you go to Digikey, and search for AC162053, it shows 18 in stock
and says it costs $35 (US). http://www.digikey.com/
Or from Microchip:
http://www.microchipdirect.com/productsearch.aspx?Keywords=AC162053

If you go to the Microchip forum and search for AC162053, there
are various threads that you can read.
Especially note what they say in this first one:

The ICD-U40 can be used as a debugger, but it requires the CCS
PCW or PCWH program to run it as a debugger. Do you have one
of those programs ? They're expensive:
Quote:

PCW Professional Package (Windows IDE with both PCB and PCM) - $350
PCWH Professional Package (Windows IDE with PCB, PCM and PCH) - $425

CCS has a special student price, so if you're a student it's possible that
you could get it for less than that.

CCS has a Standalone program for the ICD-U40, but this program only
allows the ICD-U40 to act as a programmer, not as a debugging tool.

You also bought the Kit150:
http://www.dontronics.com/diyk150.html
But according to that website, it's a programmer. So unless you buy
(or already own) PCW or PCWH, then all you have right now is two
programmers: ICD-U40 and Kit150.

I guess you mean the 16F627A and 16F648A.
If you download the data sheet for these PICs,
http://ww1.microchip.com/downloads/en/DeviceDoc/40044D.pdf
and look at the bottom of page 3, it has a chart that shows the
differences. So they are compatible but the 16F648A has a lot
more resources.
Code:

PIC        ROM     RAM      EEPROM
16F627A    1024    224      128
16F628A    2048    224      128
16F648A    4096    256      256


Did you read the links I posted to the Microchip forum ? One of them
suggests using the 16F88, because it's very similar (but not exactly
compatible), and it doesn't require a ICD header tool to debug it --
it has ICD support built-in (as do most PICs).
