I bought a CC3000 TiWi-SL from LS Research, part #450-0067.

What do you call the IC packaging type of 450-0067? I bought just the chip, not an EM because I want to interface it with an Atmega microprocessor, and I need to know what kind of packaging it is so I can buy an adapter to attach it to a breadboard.

One person on the internet said it was a 40 pin vqfn-type chip, but those have 10 pins on each side, not 9 on two sides, 11 on two sides, and 4 in the middle.

The specification just says "tray", which is not enough for me to find the right socket or converter.

The TiWi-SL from LS Research is a module. A description of this module can be found on the LS Research website below.

There is a diagram illustrating the contents of the module in addition to the CC3000 itself.

I've been through the documents. There is no information on the type of chip packaging in there. Someone on another forum mentiond that the chip packaging is non-standard and to use it I would need to have my own board fabricated and then reflow solder the chip on. This, of course, is unless I want to use one of the evaluation boards offered with the chip and antenna, which I am trying to avoid.

This is correct. You will need to design your own printed circuit board to accept the module and connect to your MCU of choice.
