Microprocessor recommendations?

From: Rocky on 17 Dec 2006 13:54 Hi All, I want to move to something bigger than a Z80/8032/PIC which I use at the moment. I would like about 50 MIPS, 1MByte Flash, 256KByte RAM - possibly all external, integrated ethernet, 2 serial ports, enought DSP capability to do 2 or so channels VOIP, the ability to self program (bootloader) for remote update. I have looked at ST, Freescale and Rabbit. The rabbit seems to be almost a fit for everything except the VOIP. Any ideas? Regards Rocky

ST have ARM9 devices now, Q1 2007 will see new Flash ARM9 devices from Atmel, and also http://www.coreriver.co.kr/product-lines/top_corerivermcu.html The titan 2 from coreriver will give 1/2/4MBytes on Chip flash, and 150MHz speeds. -jg

Can anyone recommend a cheap ARM9-based demo board with software tools? I'd like to experiment with this chip, play around with it and get an idea about its architecture. -- To reply, my gmail address is nojay1 Robert Sneddon

Look here ? http://www.atmel.com/dyn/products/tools.asp?family_id=605 or search for the ST ones STR91X -jg |
