I see that Wiznet has a new Etherenet IP stack off-load product: Wiznet 550io module.

Quick read:
  • Comes with factory assigned MAC address (Finally!! yea!)
  • Much larger than the 820 module; bad.
  • Slightly lower cost than the 820 module.
  • Uses 5500 chip. Seems about the same as the 5200 chip, e.g., 8 sockets each with TX, RX buffers
  • SPI only; no parallel interface like the 5100 chip (good riddance parallel).
  • 3.3V power, 128mA at 100BT, 75mA at 10BT
  • 5V tolerant inputs; 3.3V outputs

Haven't found a spec sheet on the 550io module. (!!) Above is from the 550 chip spec. The module has other components that do something unknown.
