Luminary Micro TM LM3SXXXX / Re: Cortex M3 and ARM news
« on: April 06, 2008, 10:04:38 PM »
Hi Mark,
I think You are right it is a manager statement. AFAIK NXP just started (second half of last year, after a more than one year delay) to ship theirs new LPC23xx and LPC24xx ARM7 cored stuff. Do You think they will come out with a Cortex version until this new kids did not get some money back?
The other thing that as I know currently Luminary and STM who are shipping Cortex cored mcus, so the market is not flodded with Cortex suppliers. I can imagine that NXP will leave them some time (a year) to see how they can perform and build the experiences into theirs own product.
Third thing that I can imagine some areas where ARM7 will be used. Is I know Cortex is not designed to support external memory or at least currently there is no mcu available with EMI peipheral. If You need an mcu with EMI You should bet on an ARM7 or ARM9 cored one. (Please correct me if I wrong.)
Time will tell.
For a new product I would (I have) choose(n) a Cortex cored mcu. If You need USB then STM32, if You need Ethernet than Luminary. The other peripherals are almost the same. Both supplier provides one quite complex software library.
Sorry for my long reply, but I'm also intrested in others opinion and hope this reply will insist some of them to share what they think.
Thanks,
Blaise
PS: Have You planned to port Your great project to STM32 as well? Or not until it will also has a member in the family with built in ethernet. (If STM plans any.)
