If you're starting off from scratch and want the smallest parts-count
system, why not an eZ80 Acclaim? 256KB of flash, 24-bit external
memory interface, built-in 100BaseT ethernet MAC, 2 UARTS, IrDA, lots
of GPIO pins, SPI, I2C and a PLL clock generator good to 50MHz as
well as ICE support and separately-powered RTC. Still Z80-compatible
(or the enhanced instruction set if you want it).
I suspect that you could dump most of what you need in the way of
CP/M programs into the on-chip flash. Add an external SRAM and
external interface "glue" and you're done, but for the programming.
