Perhaps no one new learning how to use it any more, so no one to ask.

If you need more evidence, check Freescale's "Not Recommended for New Design"
in
all HC11 listings.
We better start planning a nice funeral.

Ah, you see they can't be bothered with easy stuff. They're probably busy
fixing HC12 bugs! :)
Doesn't seem reasonable for someone to pull the plug on a healthy and tried MCU
but "reason" isn't the name of the game!
(We're slowly moving our designs towards either the MC9S08GB60/32 or other brand
MCUs.)

I bet that was true before they were a separate company that has to make
money. If selling parts to small companies made millions for maxim, microchip,
atmel, I bet they'd love to have a profitable easy to apply product that
customers actually could use in a product. Seems so obvious, doesn't it?

Seems like if the app would run in an HC05 with one accumulator and an 8 bit
stack pointer, you wouldn't have used an HC11 in the first place. Heck of a
replacement for an HC11 huh?
Lots of peripherals and real fast, but I bet a lot of speed gets eaten up
trying to make the cpu perform.

Well, the 9S08 isn't exactly the best replacement (strictly from CPU point of
view, otherwise, it's far superior) but don't forget to give the SP addressing
mode due credit. A lot of the missed functionality found in the HC11's richer
register set is offset to a large extent by SP addressing mode the HC11 lacked.
But you need to design your code a bit differently.
> Lots of peripherals and real fast, but I bet a lot of speed gets eaten up

Maybe, but the 20MHz bus and single or double instruction cycles for most
instructions more than compensates. The only real problem is that it is a bit
less comfortable to write code for HCS08's limited CPU. Other than that, I see
more pluses than minuses moving to HCS08.
Why not move to HC12 then? For my HC11-based designs, I don't need the greater
addressing capabilities and added complexity of the CPU if I can get the HCS08
to do the same job at a lesser cost. Like I've said many times before, if the
HC11 compatibility is lost (as with the HC12) there's nothing to keep me from
going to a completely different family of MCU (even outside Motorola, oops
Freescale -- you see, now I don't even have a brand loyalty factor anymore since
they changed the name, too).

================================
Main reason is lack of external expandability. If you only need the amt of
internal flash and ram provided in the 32k, 64k, 128k and 256k versions, this
gripe is a moot point. If you need more of something, you're stuck.

Bob,
I have just been going over the Freescale web site, and I haven't found any
such information. Do you suppose you could provide a url to where you
found this?

Actually that was me, not Bob.
Look at the "Orderable Parts Information" section for any HC11. All parts
have the "Not Recommended for New Design" listed in the Status column of the
table.
One sample URL:
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=68HC11F1&nodeId=01624684498635
(look at bottom of page)
I know the shock is too greate, we're all still in "Denial" stage!

Guys,
This is not news, it has not been recomended for new designs for some time, this does not
mean that it is discontinued. It is the same for the HC12 devices.
The HCS12 is recommended as its cheaper and faster.

No one said anything about any HC11 being discontinued just yet. But "Not
Recommended" is one step closer to the end. So, we need to plan ahead.
Strange thing is they don't list all available part in that section. Do you
think that means some parts are not on the "kill" list yet? If so, they
need to improve their presentation skills cause the web leaves the
impression everything's put on death row (but not dead yet).

I just re-read this comment of yours and realized you may have a
misconception about the HCS08. It's not brain-dead like the HC05!!!
You have full use of the stack. It has a rich set of stack-related
operations and a full 16-bit SP settable at any 64K address. SP can also be
used temporarily as a second index (with interrupts disabled). So, it
compares closer to the HC11 than the HC05 in capabilities, despite having an
HC05 compatible opcode map.

Last time I tried to write an HC05 prog was in the 70s I think. Was cussin
the whole time. Darn index register was only 8 bits and I couldnt port any of
my HC11 programs. Never looked at it after that. I think that's the bad memory
I had.....

RE: Test -- is this list still alive ? - Kerry Berland - Apr 13 17:45:00 2005
The good news is that by now there is a less expensive 68HC12 or 68HC908 (or
MC9S12 or MC9S08) part, with equal or better capabilities, for just about
every 68HC11 application.
These new families offer flash memory on-chip. The S series parts have BDM
ports allowing inexpensive programming and debugging in-circuit. There is
competitive pricing on a lot of these parts.
The bad news is that for existing products, some redesign will be needed.
We have products we ship to customers with 68HC11 chips in them, which were
designed years ago, and we're putting plans in place to upgrade to the 08
and 12 families.
It's my understanding that automotive and wireless communications customers
used to be the volume drivers for the 68HC11. But no new products using the
68HC11 have been designed into those high-volume markets for many years now.
For example, it's been about 10 years since GM Truck started requiring that
every body control module (doors, seats, windows, etc.) must have a
processor with in-circuit programmable flash memory. I believe that 68HC11
production volumes have gone way, way down.
The discussion lists for the 68HC12 and the 68HC08 are much, much busier. I
think it's because most engineers who used to work with the 68HC11 have
already made the move.
