WIZ550io
Overview
WIZ550io is the auto configurable ethernet controller module that includes W5500 (TCP/IP hardwired
chip and PHY embedded), Transformer and RJ45. A unique real MAC address embedded in it and it has
auto network configuration capability. When Powered on and nRESET triggered, WIZ550io initializes
itself with embedded real MAC and default IP address and can be pinged from user’s computer. So,
user doesn’t need 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.
For the detailed information on implementation of Hardware TCP/IP, refer to the W5500 Datasheet.
WIZ550io consists of W5500, MAG-JACK, a real MAC address and a tiny MCU.

READY
This pin is asserted to low after power on.

configuration with embedded MAC and default IP address inside it.
After all configuration is finished, WIZ550io raises this pin to HIGH to
inform that the configuration of WIZ550io is completed.
Host processor can only control WIZ55oio when RDY pin is HIGH.
Reset: Active low
This pin is to initialize WIZ550io.

It should be held at least 500us after asserted to LOW,

Interrupt: Active low
This pin indicates that W5500 inside WIZ550io requires
MCU's attention because of event 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.

Caution) Some users may want to reinitialize W5500 inside WIZ550io with SW reset, not handling
nRESET pin. But it makes WIZ550io hung up because all information in registers of W5500 was
cleared. A tiny MCU inside WIZ550io initialize W5500 with embedded MAC address and a default IP
address and it is triggered by nRESET. But SW reset clears all registers in W5500 and WIZ550io isn't
triggered to configure itself without handling nRESET. So, we recommend HW reset instead of SW
reset. Nevertheless if users want to use SW reset, we recommend they read MAC address and
network information including IP address, Subnet mask and Gateway address before they do SW reset,
they write those information to WIZ550io after SW reset.

SPI Operations
There is a W5500 inside WIZ550io. And SPI operation for WIZ550io follows that for W5500. For more
information about SPI operation of WIZ550io, please refer to W5500 Datasheet.
