Freescale (formerly Motorola)

Threaded View
I was wondering why there are so few
threads about the Freescale MCUs.
They don't seem to be very popular,
or am I wrong? I'm about to embark
on a small embedded project, based
on a Freescale HC08GB60 (a timer
with a couple of bells and whistles)
and because threads quite often deal
with issues about PICs, 8051s and
other small 8-bitters, a little doubt has
crept up whether Freescale is the right
choice.
Can it be the price?
Then perhaps the features that a
particular Freescale MCU offers?
The hardware support?
Development software?
Comments, please...

Cheers

Waldemar

I think they are more popular than people realize. I think that  Motorola or
Freescale haven't been doing a lot of advertising in magazines or
such that I notice. Of course I haven't bought a lot of MCU types of
magazines lately. But I am signed up for Freescale's email notification
services.
The last big promotion they did a couple of years ago was the huge
68HC908QT4 giveaway EVAL board promotion,
which was pretty neat. The 68HC908QT4 piqued my interest as it is a small 8
pin MCU with an ADC and UART built in, and 4k of Flash.
I still think they have the only 8 pin MCU with a ADC built in.
I think most users of these chips are getting support for them elsewhere.
The 68HC908xxxx series chips are so similar to HC11's that I think most
people get support through other sources
that cater to the HC11's.

I am a big fan of the DSP56F800 series myself. So if I have a question or
problem I get my support through www.newmicros.com.
Several of these chips are perfect for motion control, CNC, robotics
applications. They have something like
six PWM channels, three or four quad timers, built in quadrature decoders,
ADC's, etc.
Several other chips are excellent for different kinds of DSP applications as
well.
These are 16 bit processors that run at up to 80 mhz clock speed. Some new
chips run up to 120mhz clock.
The tools that are available aren't as good as some other chips, but they
have a nice selection to choose from.
Peter Gray has the Small C compiler http://petegray.newmicros.com/ for these
chips.
www.newmicros.com has tremendous support for their boards using these chips,
plus they have the ISOMAX system and MAXForth (for other chips as well),
plus a nice assember too.
www.forth.com has a nice Forth compiler (for just about all the different
MCU's) too.
www.metrowerks.com has the Codewarrior C++ compiler.

For your chips www.imagecraft.com has an excellent C compiler that works
well. I used it with the little tiny 68HC908xxxx chips myself. Plus
www.metrowerks.com has a Codewarrior version that works well too. Freescale
through Metrowerks offers a free 4k or 8k limited compiler for these chips
depending on which chip your using. I think it is 4k limited for the
68HC908QT4 (et cetera) types of MCU's and 8k for the DSP56F800 series. But
it could have changed recently.
I think one could modify or get a version of the GnuCC compiler for these as
well.





Re: Freescale (formerly Motorola)
For information :
- The QT4 doesn't contains an UART ; on the QT demo board, it was a software
UART
- CodeWarrior (Metrowerks) is now limited to 16Ko.

but only CW for the HC12!? HC08 still 4K AFAIK, isn't it?

Not by a long shot. I know Microchip has several - see
http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId13%35&dDocName=en010114
for instance.

And for those who care, Microchip has some 6-pin MCUs.

None with ADC unfortunately.  I had a perfect app, if such existed.
One analog in, one discrete out, a tiny bit of code, and presto...  Oh
well.

  Silicon Labs, and Philips (coming) also have 3mm x 3mm package uC,
only theirs DO have ADC...

...and a heckuva lot more in a package twice the size of a PIC10...

I've sorta given up on Cygnal/SiLabs.  They look like fun chips to
work with, and quite powerful, but every time I had Purchasing quote
one of their controllers, it came out 2x the next worst competitor.
Digikey's price for a single C8051F300 is over US$6.50, and about
US$3.60 for 1500.

And I don't need all that much power for the app I had in mind.  The
PIC10 is less than US$0.50 in quantity (Digikey's price for a single
is about US$1).  Anything less than a buck (with an 8-bit ADC) would
have made it worthwhile.

Think the ATtiny13 and ATtiny15 (and soon t25/t45/t85) should fit that
description nicely as well.

Yes, you are wrong, Mot/Freescale is one of the biggest suppliers of
microcontrollers. The reason there are so few threads about these is
that everything about them is so very well documented that people just
don't have any problems to discuss about these wonderful semiconductors.

You forgot the ";-)" didn't you? Only able to talk about 68HC12 here,
but the documentation to that part is about the worst piece of tech
write I've ever seen. If you want unclear, obfuscating, verbose and
chaotically organized docs, then go for Motorola. I don't dispute the
status quo of documentation of other, marginal microcontroller
vendors, but big big Motorola should be able to afford at least some
input from a competent tech editor when producing another 400 page
handbook for their mcu's.

because Motorola/Freescale seems to prefer big customers (e.g.
automotive), with direct support etc. and those rarely write in
newsgroups.

The devices are not so simple to get in small quantities, there are no
"free" and good tools. You need to spend some money to have fun (e.g.
for a BDM interface).

IMHO the performance/price ratio is similar to other uCs.

And the BDM interface is great (non-intrusive access to memory while
target is running).

they have own (non public) groups in Yahoo
not listed in the public Yahoo directory.
E.g. groups.yahoo.com/group/68hc05_08/ and
they recently started a new and own community page
at www.freegeeks.net Further everybode can sign at the freescale webpage
for registration and mail to the freescale product specialists worldwide.

There are active mailing lists for the 32-bit microcontrollers - I don't
know about the small ones.  We've also had lots of information from our
distributers.

Quoted text here. Click to load it

For the smaller devices, the CodeWarrior tools are (as far as I know) free
or cheap for limited sizes of program code, though they are expensive for
the unlimited versions.  BDM interfaces should be reasonably priced.  For
larger devices (i.e., 32-bit chips), there are gnu tools, cheap BDMs, and
open-source OS'es.  I can't comment much on the availability of small
quantities, however.

there are also very active lists for 8/16 bit controllers, but the
people I wrote about also don't look/write in mailing lists.

4K for HC08, 12..16K? for HC12.

Quoted text here. Click to load it

but for a "really good" BDM interface you have to spend a noticeable
amount.

GCC also for HC11/HC12 but last time when I looked at it (two years
ago or so) producing poor code.

I have no problem getting the chips via www.digikey.com in small quantities.
I haven't tried getting samples from Freescale yet.
