2. Introduction
USR-ES1 is the Ethernet module of a SPI interface, interface is TTL level of 3.3V, power supply voltage
of +3.3V, please ensure that the current is not less than 200mA, voltage is continuous and 3.3V.
2.1 Function Characteristics
 High speed SPI interface 80MHz
 Hardware-TCPIP-protocol stack user built in, almost without understanding the complex network
protocol knowledge

Supports up to 8 Socket
 Support TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE protocol
 Integration of the data link layer, physical layer
 Support the wakeup
 Support high speed serial peripheral interface (SPI model 0, 3)

Internal 32K bytes receive buffer
 The embedded 10BaseT/100BaseTX Ethernet physical layer (PHY)
 Support auto negotiation (10/100-Based full duplex or half duplex)
 Does not support the IP patch
