There is a whole range since 1993 http://developer.axis.com/products/etrax100lx/etrax_history.html The 100LXsupports 100Mbs full duplex They are used by Axis in their surveillance cameras one of their boxes has an etrax 100LX + TI DM642 + camera chip.

Why do some NIC's perform MUCH better than others even though they are all spec'd at 100MB?

I felt it was safer for me to alert people to a potential problem and for these same people to then check for themselves BEFORE buying the kit, than for them to buy the kit and find out AFTER the event that there was a problem.

Try this: http://www.logicpd.com/eps/som/sharp/LH79524/ There is a free 2.6.x linux port as well. goto http://www.sharpmcu.com. You can sign up for their freely available software library and it should be in there. -Z Sergio Masci wrote:> On Sat, 17 Sep 2005, Alex Gibson wrote: > > > > > "Sergio Masci" <sergio@NOSPAM.xcprod.com> wrote in message > > news:Pine.LNX.4.61.0509151601450.29603@yoda.srts.co.uk... > > > On Thu, 15 Sep 2005, Alex Gibson wrote: > > > > > > > >> > > >> Etrax from Axis http://developer.axis.com > > >> More recent chips can run a default 2.6 linux kernel > > >> > > >> The ETRAX 100LX Multi Chip Module includes the ETRAX 100LX SoC plus 4 MB > > >> Flash, 16 MB SDRAM, Ethernet Transceiver, etc. This chip is ideal for > > >> Ethernet-connected Linux systems. > > >> http://developer.axis.com/doc/hardware/mcm/4+16/MCM_datasheet.htm > > >> http://developer.axis.com/products/etrax100lx/index.html > > >> > > >> a.. 4 asynchronous serial ports > > >> a.. 2 synchronous serial ports > > >> a.. 2 USB ports Host 1.1 > > >> a.. 2 Parallel ports > > >> a.. 4 ATA (IDE) ports > > >> a.. 2 Narrow SCSI ports (or 1 Wide) > > >> > > >> http://developer.axis.com/doc/index.html > > >> http://developer.axis.com/products/etrax100lx/18354_etrax_lx.pdf > > >> http://developer.axis.com/doc/hardware/mcm/4+16/MCM_datasheet.htm > > >> > > >> http://www.acmesystems.it/ A nice small board , and its 5V tolerant > > >> > > >> Alex > > >> > > > > > > I had a look at axis a little while back but I couldn't find any info on > > > the MIPS rating.

Oh ya...this is based on the LH79524 with a 77MHz ARM720T with ENET MAC, USB, ADC, RTC, GPIO, etc. There is a LCDC but if you don't need it, it's nearly free and leaves you with extra GPIO. There is a 16-bit data-bus version as well that may be easier to handle cause its a QFP rather than BGA. The QFP version is the LH79525.

Check out the ARM boards from Embest at http://www.armkits.com/Product/productmain.asp Hope this helps. -- Dennis Don Gravos wrote:> I am looking for small embedded ARM board with ethernet+USB+multiple > RS232+general purpose parallel I/O lines+multiple channel ADC+realtime clock > and capable of running Linux.
