What do you believe the min cpu speed is? I've operated the TS7200 board
with CPU clocked at aprox 2.5MHz. The min cpu clock rate for ethernet to
work is 40MHz.
Even on the ts7200 (which, unlike the ts7260, is not designed for very low
power) I got as low as 0.8W with a very low cpu clock and the ether phy
turned off. I'd have thought that the 7260 in the same sate would have use
quite a bit less power.
