Pin numbering of a PLCC_32 socket

[ljcox]

Does anyone have the pin numbering of a PLCC_32 through hole socket?

I did a Google search but could not find a 32 pin socket with the pin numbering.

The IC data sheet only gives the pin numbering on the IC. I need to know how to connect to thepins on the PCB.

Any advice will be appreciated.

How about this?

Thanks, but that is an adapter.

I need the pin numbering of the PLCC 32 socket.

Any PLCC32 to throughhole device is likley going to be an adapter. They're usually surface mount. They should be keyed in some manner. Exaclty what IC are you talking about, what connector?

No I managed to buy some sockets.

I intended to take a photo, but my wife has gone away for a couple of days and has taken the camera with her.

So my apologies for the poor scanned image.

I can, of course, use a multimeter to buzz out the connections if I have to, but would prefer a diagram.

The meter is probably going to be the only real way, unless someone around here happens to know off the top of their head. BGA adapters aren't commonly used by electronic hobbiests.

Look at the bottom of the socket under a microscope. Most that I have seen have tiny markings.

Thanks for the tip. I can't see anything with a strong magnifying glass, so I'll borrow a microscope.

hi len,

Attached a Z84SKT1.pdf, showing a larger plcc84, it may help to decypher the plcc32, they are arranged in the same sequence.

try this:
