WIZ550io is an auto configurable Ethernet controller that includes a W5500 (TCP/IP hardwired chip and PHY embedded), a transformer and RJ45.
It has a unique real MAC address and configures the network setting automatically. When powered on, WIZ550io initializes itself … with embedded real MAC and sets the default IP address (192.168.1.2) and it can be pinged. Therefore, users are not required to write MAC and network information like IP address, Subnet mask and Gateway address. The WIZ550io is an ideal product for users who want to develop their Internet enabling systems rapidly.

---|---|---|---|---|
J2 | 1 | P | 3V3D | Power: 3.3V Power Supply |
::: | 2 | O | RDY | READY This pin is asserted to low after power on. When RSTn is activated, WIZ550io does auto configuration with embedded MAC and default IP address. After configuration gets completed, WIZ550io raises this pin to HIGH in order to inform about the completion of WIZ550io’s configuration. Host processor can only control WIZ55oio when RDY pin is HIGH. |
::: | 3 | I | RSTn | Reset: Low activity This pin is to initialize WIZ550io. Hold at least 500us after asserted to LOW and wait for at least 150ms after it is changed to HIGH until WIY550io configured itself. |
::: | 4 | I | NC | Not Connected |
::: | 5 | O | INTn | Interrupt: Low activity This pin indicates that W5500 inside WIZ550io requires MCU's due to events like socket connection, disconnection, data receiving timeout and WOL (Wake on Lan). The interrupt is cleared by writing IR register or Sn_IR. All interrupts are maskable. |
::: | 6 | P | GND | Ground |
⚠CAUTION
Some users may want to reinitialize W5500 inside WIZ550io with SW reset, not handling RSTn pin. It will make WIZ550io hang up due to clearance of all information in the registers of W5500. A tiny MCU inside WIZ550io initializes W5500 with embedded MAC address and a default IP address and Initialization is triggered by RSTn.
In case of SW reset, all registers in W5500 will be cleared and WIZ550io will not initialize itself. All information inside WIZ550io will be lost and WIZ550io will hang up instead.
Therefore, we recommend HW reset instead of SW reset. Nevertheless, if users want to use SW reset, we recommend to save MAC address and network information including IP address, Subnet mask and Gateway address before SW reset, and writing those information to WIZ550io after SW reset.
