 		 #114558 - LOTS of memory
Responding to: ???'s previous message
Well, the smaller of the two memory sizes I was using, back then, was 4Mx32, which was in a single IC. I only needed a small (32Kx8, 8 ns) external SRAM buffer to keep up with an externally managed communication process, but we did use a 4MByte FLASH to boot the thing.

I haven't recently looked at ARM MCU's. Do they come with 4MBytes of internal FLASH and 16 MB of internal RAM nowadays? We also had a requirement for two entirely isolated Ethernet channels for which we wanted internal PHY's, and while we needed no serial port in our app, it was handy for debugging.

One of the ARM-7's had two HDLC channels that had promise, but the ethernet PHY's built into the ARM-9 were so attractive we went with that.
