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