I need about 22 or so I/O pins to do what I need to do, and I am using the SSOP-28 package. The crystal is almost bigger than the chip in this case. An 8051 might be a possibility, but I'm not sure if I can get enough usable pins with an I2C function in the same package. I'm past half-way in the design and don't really want to jump chips in mid-stream. I'll take a look at the Phillips product offerings though, and see if anything they have fits the bill. There are so many 8051 variants nowadays, it's hard to tell which ones are "real" part you can get. Whereas I can usually trust the Microchip people in this regard.
