Hi all, Just wondering what people think of the Atmel AT91 ARM Thumb chips? The "AT91RM9200-QI-002" looks pretty interesting. It is 180MHz pqfp 208 package. Are these supported by the arm/thumb GNU toolchain? Anyone selling evalboards for these chips? cheers, Jamie Morken

For much higher-performance applications, e.g. DSP-heavy functions, they're a good choice. It's more work to build them into a complete functional system, however. 2. Yes, and 3. Atmel, at the very least. IIRC their ARM9 EVBs are quite expensive though. -- -- Lewin A.R.W.

> are there any more general groups for discussion of the lower end of > ARM CPUs? the company I work for are just about to release an Oki ARM7 I think your best bet would be to discuss on Usenet in comp.arch.embedded and comp.sys.arm. There are many ARM developers there, and in fact I recall someone mentioning Atmel's higher-end parts there within the last month or so. Interesting on the Oki parts. One of our semi reps has been trying to sell me on those parts for a while, but I just never get time to evaluate them. Looks like our next ARM-based system will be built around XScale. -- Lewin A.R.W.

On the Oki parts..... they have a few product series based on ARM7TDMI for gen.purpose applications and are pretty cost effective... (okisemi.com/us) they may be worth looking at if also considering Philips. --- In , "Lewin A.R.W.

The Oki chips are very nice parts. They are almost the only company selling off-the shelf general purpose ARM7TDMI chips with an SDRAM controller (what ARM7 AT91s lack). They were a little bit difficult to source in small quantities though, but I think that is improving now. Price is very good for medium and large volume projects (between US$5-$10). Nice is that they come in QFP and BGA packages. Regards. -- /"Inventiveness has not yet come to an end.
