One reason that you are more familiar with PIC and AVR is that they are
actively marketed to hobbyists. The tools are cheap, and the parts can
be easily bought in low volumes. Most other manufacturers avoid this
market. I used a small 8 bit Mitsubishi MCU a couple of years ago, and
the development system was $6000. Not many hobbyists will ever see
these parts, but they were right for the application and the $6000 cost
was easily amortized over the first year's forecast of 100,000 units.
In the past five years, I've designed products with MCUs from Samsung,
Toshiba, ST, Philips, and Cypress. Most of these vendors won't even
talk to you unless you're looking at tens of thousands of parts a year.
Oh... None of these would have their "real" part numbers on them. They
would have a part number made up by my client.
