1. Quick Start
Hardware Requirement:
1 MCU development board(we use one kind of STM32F103RBT6 core board), +3.3V power from core
board, Network cable, USB to TTL converter.
The hardware connection diagram as follows:
Diagram 1-1 Connection Diagram
Because here the use of the 3.3V micro controller system, so the middle without adding a level
conversion.

3. Hardware Description
3.1 Hardware
A total of two sets of pins, the first group and the second group.
3.2 Pin Definition

SPI to Ethernet Module www.usr.so
Jinan USR IOT Technology Limited 8/11 [e-mail]
Pin Name Function
1 - 1 GND Ground
1 - 2 GND Ground
1 - 3 MOSI SPI Master Out Slave In
This pin is used to SPI MOSI signal pin.
1 - 4 SCLK SPI Clock
This pin is used to SPI Clock Signal pin.
1 - 5 SCSn SPI Slave Select : Active Low
This pin is used to SPI Slave Select signal
Pin when using SPI interface.
1 - 6 INTn 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.
2 - 1 GND Ground
2 - 2 +3.3V Power : 3.3 V power supply
2 - 3 +3.3V Power : 3.3 V power supply
2 - 4 NC Not connected
2 - 5 RSTn 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.
2 - 6 MISO SPI Master In Slave Out
This pin is used to SPI MISO signal pin.

4. Develop Tools
4.1 IAR Embedded
IAR embedded workbench. currently support ARM IDE. (other IDE tools also support ARM IDE, for
example, such as the Keil). software version is for ARM 5.41 embedded workbench. On how to use IAR, see
the IAR manual.

6. FAQ
6.1 No communication
Power use 3.3V power supply after, to ensure that current above 200mA.
6.2 IAR routine compilation errors
IAR compiler environment, use IAR5.3, 5.4 version, version of IAR6.5 due to the difference in the official
library, will be an error situation, you need to reinstallIAR5.4 or manual modification to eliminate these errors.
6.3 No communication, cable connection does not recognize
W5500 does not support Auto-MDI-X, which does not support the cross connect switch automatically, for
some older equipment, may need to cross line specific or direct connection. Such as modules connected
module, require the use of cross line, module. The router or switch requires the use of straight line.
