#188435 - Did you ever try the Maxim/Dallas DS89C4x0?
Responding to: ???'s previous message
These have been available since '99 and have had auto increment/decrement of each of the two data pointers all the while. That's the main reason I like 'em so well. The fact that they were initially designed to run at 50 MHz was originally an influence, too, but they've toned down their claim to 33 MHz.

If I don't run any timing in firmware, I can simply substitute a 33 MHz oscillator for the usual 11.0592, and I can run the serial port (which I seldom use) at 57600 baud without any changes.

Can you adjust the external bus cycle timing on that ATMEL part?
