(Would it be too much to ask that you not use one-long-line paragraphs?)
In this same instrument is a Motorola MC68HC11A0FNC11W
in a PLCC-52
package. I need to find a viable replacement for it as well. I've
had a harder time tracking down possible replacements for it. The
only ones I've come across so far, that are available without an
enormous minimum purchase, are the MC68HC11E0CFN2, the
MC68HC11E1CFN2, and the MC68HC11E1CFN3.
I believe I have a 68HC11 doc book somewhere; in case you don't find
what you need, tell me and I can try to dig it out and see if it
explains the suffixes in enough detail to tell whether any of those
should be workable replacements.
I do know this much: The Motorola part is operating
with an external
EPROM, so the chip itself is ROMless.
...or running with the ROM disabled; memory (from when I last read that
book) says that a 68HC11 with ROM can be configured to run as if it
were ROMless.
