Pin Name
Ground
Ground
SPI Master Out Slave In
This pin is used to SPI MOSI signal pin.
SPI Clock
This pin is used to SPI Clock Signal pin.
SPI Slave Select : Active Low
This pin is used to SPI Slave Select signal
Pin when using SPI interface.
Interrupt : Active low
This pin indicates that W5200 requires MCU
attention after socket connecting,
disconnecting, data receiving timeout, and
WOL (Wake on LAN). The interrupt is
cleared by writing IR Register or Sn_IR
(Socket n-th Interrupt Register). All
interrupts are maskable.
Ground
Power : 3.3 V power supply
Power : 3.3 V power supply
Power Down : Active High
This pin is used to power down pin.
Low : Normal Mode Enable
High : Power Down Mode Enable
Reset : This pin is active low input to
initialize or re-initialize W5200.
It should be held at least 2us after low
assert, and wait for at least 150ms after
high de-assert in order for PLL logic to be
stable.
SPI Master In Slave Out
This pin is used to SPI MISO signal pin.
