We're planning a new design for what amounts to a data bridge between
ethernet and a 32 bit memory mapped device. This is in a battery-powered
device, so low power consumption is critical.
The 5282 seems like a reasonable choice; it's pretty mature, though, and
I was wondering if anyone might be in the know, or have opinions on its
suitability for a new design, and maybe what alternatives might be good
to consider.
May I suggest the MCF5208 with 1.8v DDR and Flash. It does not do very
much, but it does it very quickly and it draws a fraction of the power
consumed by the MCF5282.
You can get a M5208EVBe evaluation board for little more than the cost
of the USB-BDM pod included in the kit. I believe it is available
through major distributors and even DigiKey. Just make sure you get the
M5208EVBe and not the M5208EVB (sans 'e') which is older and consumes
more power.
If you could talk to your 32bit mm device with only 16 bits, you could
just copy and paste the M5208EVBe into your product.
Bfn,
Bob Furber
