 		 #111240 - That's what I wanted to avoid.
Responding to: ???'s previous message
I have need of 2 MB (1M x 16) of code memory on an MCU that has a bus cycle too short for the typical 70ns FLASH memory.

I know one can shadow the FLASH, but that requires additional hardware, and these parts have pretty fine-pitch leads, which makes "scabbing-on" an other part a difficult and questionably reliable process.

Do the serial flash makers produce serial devices of that capacity?
