What about MC68HC908QC08/16: is it a ghost?

It seems to be a valid low cost alternative to 16 pin QB family where you need just some more pin, up to 28.

It is listed on "Freescale's 8 bit product summary 1q 2006" and it placed between 908QB and 908AP high performance / low cost, repacing 908EY16 which definitely seems to be phased-out (why? boh...)

There is a Demo board, a fact sheet and an Errata mask set document. But no data sheet nor availability....

Any news on that?

The MC68HC908QC08/16 has been delayed and is now set to launch later this year, probably late Q2. When the Q1 2006 8-bit Products Summary was put together, they probably felt safe putting it in as "New!"

The EY16 is actually on the Product Summary also (down in the Application-Specific Products section and it is very much alive.

(I have to add the usual disclaimer that any quoted dates are subject to change...)

Yes, perhaps 908EY is not dead, not still, at least. Its final executioner will be 908QC...

At just half the price and with only 4 less pin (perhaps not so important anyway) it has exactly the same attractive peripherals, ESCI, 10 vs. 8 10bit-ADC channels, 4 vs. 2 timers and, not least, a low cost modern demoboard. A bigger 908QB which is worth every cent it costs.

At the same price you may have much more from the wide freescale 8-bit cpu range, either older HC908 (908AP32) or the newer much more powerfull 9s08AW16/32.

Obviously If Freescale would have pushed the existing 908EY which is not bad at all but costly, they would have proposed it at the same projected price for the QC: at that point no matter for 2 ADC lines more or less or 2 more timers. Better an egg today than the hen tomorrow.

And we would have not another CPU in the (too much) crowded 8 bit arena. I think that they could have better spent their efforts to place something like 908QC in the much hotter middle between 9S08QG8 and the 9S08AW16, with 5V supply too.

What a pity we must still wait...
