Re: Freescale's new roadmap - 9s12 not looking good? - Mark Butcher - Jun 1 14:20:29 2008
Hi All
Concerning use of NE64 (not other types of HCS12) I suggest anyone
presently using them due to the Ethernet connection to seriously
consider the new Coldfire devices for any new projects.
We have used the NE64 since its introduction in 2004 and have had good
experience with then, and - in parallel - used the M5223X Coldfire
types since mid-2006.
The fact is that the NE64, although a nice device for some small
Ethernet application and a good spring-board to the more general
Colfire family, has no future because it doesn't suit any long term
development strategies. Freescale has made the only logical decision
to move emphasis from it to the more suitable, and capable, Coldfire
range.
This is not something to be sad about but rather to use as a chance to
move to the low cost Coldfires and benefit in the long term vastly
more than by staying with the NE64.
- The new Coldfires are cheaper than the NE64 (see
http://www.utasker.com/forum/index.php?topic=256.0 for an overview)
- The Coldfires are more powerful.
- They have more and more-advanced peripherals.
- They have great development environments which are essentially free
of charge (up to 128k program sizes).
- They have low cost development boards, including all debugger
support needed.
- For GNU users the open-source solutions are also very efficient for
the Coldfire.
- The Coldfires are generally easier to work with due to their clean
and powerful 32-bit architecture.
I admit to shedding a tear once realising that the NE64 was doomed to
be a one-off. But once you have used a Coldfire and realised its vast
advantages over the NE64 for Ethernet based projects you too will not
want to look back again...
