 		 #111380 - program/erase cycle isn't important
Responding to: ???'s previous message
What's critical is the read cycle, since this is program space in which the FLASH lives. Now, the MCU is not of a "harvard" architecture, so code and data can coreside, but it already uses a considerable amount of the currently available 1 MB. I need to expand the memory in order to allow for more code, and I need to increase the speed. I'm just looking for a fast FLASH with the "usual" parallel interface.

The fastest parts I'm presently seeing out there are 70 ns Taacc parts. That's too slow.

Has anybody seen FAST FLASH?            01/01/70 00:00      
   nope but then again......            01/01/70 00:00      
      It's not an 805x            01/01/70 00:00

                     are you desperate enough?            01/01/70 00:00      
                        I didn't expect an easy fix.            01/01/70 00:00
