I've also moved most of my stuff to 18F chips, but there's an application
I'm working on now where I really don't need very many pins (I'm using
external serial peripherals), but I'd like a fair amount of RAM and ROM.
The smallest 18F I see is about 28 pins, and I get to pay for those pins
whether I use them or not. So, are there any low pin count 18F chips I'm
missing? I need at least one UART (two would be nice, but I could bit bang
one), an SPI, but no A/D. Seems like 8 I/O lines would do it. Another
consideration is I have a C compiler for 18F, but not for 16F. However, I
don't want to build a per unit cost into the design just to save the cost
of another compiler. I COULD write it in ASM, but C is spoiling me...
