[En-Nut-Discussion] ENJ28J60

[Bengt Florin]

Also the current status of the ENC28J60 (Rev B4) silicon makes it
practically unusable for most CPU's, as the SPI interface doesn't work
properly for clock rates under 8MHz.

Silicon Rev B5 is said to correct this, but Microchip has yet not announced
when this will be available.

Also, I agree to Haralds comment. Power consumption is way too high.

Another interesting CPU to port Nut to would be the Freescale Coldfire
MCF52235, a true single chip solution as it also contains an Ethernet PHY.

I remember reading some comments from Erik Lins to port Nut to Coldfire
MCF5282.
Well yes, it was back in 2004. Time flies.

Any interest of, or progress in the Coldfire direction?

Hello Richard,

After Erik Lins pointed me to the electrical characteristics,
namely the operating current, I lost my interest in this chip.

Due to missing hardware (Medianut still uses the old VS1001K),
we never worked on an update. I agree that this is very sad.
