Has anyone here tried at the Fairchild ACE 1101 microcontroller?  It's
in an 8 pin TSSOP, has 1K bytes of program EEPROM, 64 bytes of data
EEPROM, and 64 bytes of RAM.  The data EEPROM is memory mapped rather
than I2C.  Apparently Fairchild announced it back in January, but I didn't
hear about it; I only found it because I was browsing their web site looking
for replacements for really old logic/interface devices (such as the 8093;
I didn't find anything).

Since Fairchild was spun off from National not that long ago, I wonder if the
architecture is similar to the COPS-8 series?

Hey, Eric, this chip looks hot! I've been wondering how long
it will take before we see some other low-cost 8 pin and 14
pin micro's. The bottom-end AVR's are still around R1.50.

I am also interested in the results, if someone is going to
test these beauts. What sort of dev tools do they have?

Maybe Walter will know. Bytecraft makes a compiler
for the COP8 if I recall correctly.

I see it's also got 7 addressing modes, 4 interrupts,
capture/compare/PWM and linear program space (no banks).

Hi Eric. I didn't tried it yet but couple months ago my company suddenly
has been visited by sale reps from Fairchild with offering to migrate from
low ends PICs to ACE 8 pin family. They promised that those chips will be
cheaper for us than any offering from mchip ;-)

WBR Dmitry.

I see the volume pricing is still a little bit more than
Mchip, but a lot less than the Atmel Tiny AVR's. It is
flash though. I see they also have them in 14 pin packages.

I couldn't see from the datasheet whether some pins are NC,
or just not shown in the data sheets. Does anybody know if
these parts are ICD?

re: Fairchild ACE comments from Eric, Tjaart, and Dmitry

  Well, just to make an `absolute fool' of myself... A local rep who
normally provides me with Lattice Semiconductor and Dallas Semiconductor
data and samples, recently asked me take a look at the Fairchild ACE line.
My recommendation was that it is not suitable as a replacement for the PIC
in similar applications. I went on to say that the 68x, PIC, AVR, Z8x, and
80x processors dominated this market in the USA.

  My question to you folks (whom I have the greatest of respect), is what,
in the ACE product line, would motivate you to commit to new development
tools and how much `faith' do you have in Fairchild's commitment? While
Fairchild is `legend', in recent years, it has been `tossed around'. They
certainly have access to production capacity but what if they run into
financial trouble? I'd suspect, ACE would go before logic...

  If I'm wrong here, I'll get back to my rep, `with my tail between my
hind legs' and give him an update. I just don't see the ACE line competing
with what's on the market but I may live to eat my words and it won't be the
first time... I'd appreciate your opinions. Thanks,

  - Tom

My point of view that ACE can be discussed as a substitution for 12C5xx and
for some specific application also for 16C5x. The main question is pricing
for big quantities.

Both models look good. The 1k device could actually replace
a 16C505 that I have just designed into a product. The only
thing keeping me from changing is the price. The 16C505 OTP
is *slightly* cheaper than the Flash ACE. The code will be
simple, so I don't foresee changes to it.

I saw this device this week for the first time, so I haven't
had the chance to give it the time it deserves. It seems
the stack is 8 deep, and that you can actually get to it.
Nice. The current consumption is also good.

I've heard a birdie whistle about nice dev tools for these
new low-end devices. I don't know anything more. I do know
that the chances of me spending on new dev tools for Mchip
are, uuuhm, slim.

As to the question of them being tossed around, they listed
this month, they will probably push very hard to sell devices.
I am hoping for a price war. CHeck out the announcement :

It would seem that there may be a price war soon on the cost of silicon,
but to many of us the development tools are what decides if we use a device
or not. In the past it has taken long periods of time before "Stable" and
usable development tools that provide a "Reasonable" time to market
solution has been provided. We all await for this situation.

I have been taking a good look into the TI range with the MSP430 range of
controllers. Yes the instruction cycle is slow (200nS @ 5MHz) but the
current consumption is low and the tools are great. Ah JTAG development is
great, and the chip cost well TI quote around $1 for a ROM version, but
that is not for me...
