W5500 Nano Ethernet Network Module

introduction

This product is W5500 Nano Ethernet Network Module. Model name is HY-W5500-NanoThis W5500 is a Ethernet module that basic on the new type chip W5500, The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier internet connection for embedded systems using SPI (Serial Peripheral Interface). W5500 suits users in need of stable internet connectivity best, using a single chip to implement TCP/IP Stack, 10/100 Ethernet MAC and PHY. Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE, …, which has been proven through various applications over many years. W5500 uses a 32Kbytes internal buffer as its data communication memory. By using W5500, users can implement the Ethernet application they need by using a simple socket program instead of handling a complex Ethernet Controller. It is possible to use 8 independent hardware sockets simultaneously. SPI (Serial Peripheral Interface) is provided for easy integration with the external MCU. The W5500 SPI supports 80 MHz speed and the new efficient SPI protocol, so users can implement high speed network communication. In order to reduce power consumption of the system, W5500 provides WOL (Wake on LAN) and a power down mode.

technical details

- Module size: 23mm x 26mm
- Power supply: 3.3v or 5v - 12v, When use 3.3V voltage input(P1 PIN1),5v input pin must floating (P2 PIN1).

When use 5v - 12v voltage input(P2 PIN1),PWR_EN (P2 PIN4) must high level(3.3V or 5V), P1 PIN1 output 3.3v.

SPI clock frequency(MAX): 80M
Work current(typ): 130mA
W5500 does not support auto-MDIX feature. Thus, user should use straight-through cables to connect to other switches or routers and crossover cables to connect to devices such as servers, workstations or another W5500. However, user can use either type of cable to connect to other devices with auto-MDIX enabled, and the interface automatically corrects for any incorrect cabling.
For example, W5500 connect PC, must use crossover cables, PC close auto-MDIX switch to 100MBPS full duplex.
