<DIV>Check out the Freescale Kinetis K60 (100MHz ARM Cortex-M4). They are available in 100 & 144 pin LQFP (as well as 144 pin MAPBGA!) form factors, ideal for mounting on SchmartBoards for easy proto-soldering. The part I recommend is PK60N512VLQ100 (144 pin), and it's available from Digi-Key in single quantities for $14, but is much cheaper in volume.</DIV>

<DIV>Since you didn't specify what your actual MCU price range is, it may not be ideal.</DIV>
