VTP - Very Tiny Parts

A while back, I wrote about a new ARM Cortex M0+ chip from Freescale. It's not the first M0+, but I do believe that it's the smallest. I've been checking stock off and on and finally found the smallest package to be in stock and available to ship.

I actually bought a couple of different types. First, there's the WLCSP 20. It's got 32K FLASH, 2K SRAM and an 8K bootloader. The real kicker is that the package is only 1.6mm X 2.0 mm. I also got a few in the QFM 16 package, which is a bit more workable at 3mm X 3mm.

Finally, I bought a Freedom development board with th 4mm X 4mm QFN 24 package. The dev board is hardware compatible with Arduino shields, so that will make for some interesting possibilities.

Anyway, here at Screaming Circuits, I'm most interested in that 1.6mm X 2.0mm package to see how easy (or difficult) it is to use - see if there are any particular layout challenges. The other stuff is just for after hours play time.

I'm not a number. I'm a free development board!
