USR ES1 W5500 SPI to LAN Ethernet Network Module Converter TCP IP SPI Interface

Description: USR-ES1 is embedded with Wiznet’s W5500 chip, and uses hardware logic gate circuits to implement the transport layer and network layer of the TCP/IP protocol stack (such as: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE and other protocols), and integrates Data link layer, physical layer, and 32K bytes of on-chip RAM Cache for sending and receiving data. Make the host computer main control chip only need to undertake the processing task of TCP/IP application layer control information. This greatly saves the workload of the host computer for data replication, protocol processing, and interrupt processing, and improves system utilization and reliability. During operation, users can use W5500 as a peripheral RAM of MCU, which is very simple. The external interface of W5500 is a general 80MHz high-speed SPI, which can be selected for different platforms to expand high-speed Ethernet solutions. Auto-negotiation LED status shows that the SPI interface is fast and stable. The size and pins are compatible with Wiznet's official module WIZ820io Features: 1. 80MHz high-speed SPI interface 2. Built-in hardware TCPIP protocol stack, users hardly need to master complex network protocol knowledge 3. Support up to 8 Socket connections 4. Support TCP, UDP, ICMP, IPv4, ARP, IGMP.PPPoE protocol 5. Integrated data link layer and physical layer 6. Support wake up after power failure 7. Support high-speed serial peripheral interface 0 (SPI mode 0~3) 8. Internal 32K bytes transmit and receive buffer 9. Embedded 10BaseT/1 00BaseTX Ethernet physical layer (PHY) 10. Support auto negotiation (10/100-Based full double earth/half double earth) 11. Does not support IP fragmentation 12. 3.3V working voltage, 1/0 signal port 5V withstand voltage 13. LED status display (full duplex/half duplex, network connection, network speed, activity status 14. Ultra-small pin-type package, convenient for embedded applications 15. Provide C application routines Product parameters: 1. Power supply mode: 3.3V external power supply, current should be greater than 200mA 2. Control interface form: 3.3V TTL level, _SPI interface, 2*single row pin 3.PCB size (MM): 23* 25 mm 4. Mechanical size (length * width * height): 28.5* 23* 24 mm Pin description: GND: ground, power negative VIN3.3: 3.3V power supply positive PWDN: Pin is used for power down mode High level: power-down mode enabled Low level: Normal mode enabled nREST: This pin is active low, used to reset and re-initialize W5500 MISO: SPI master input and slave output MOSI: SPI master output and slave input SCLK: SPI clock pin nSS: SPI chip select pin, active low nINT: interrupt pin, active low Precautions : This module is not a SPI-to-Ethernet transparent transmission module, it needs to be used by an external microcontroller, and the user needs to understand the use of the W5500 chip, and provide STM32 example codes. The W5500 module is an Ethernet module based on the W IZNET main push model W5500. The module integrates the full hardware TCP/IP protocol. I do not need code to implement the TCP/IP protocol stack, support 10/10OMBPS transmission rate, support sleep mode and network. Wake-up, integrated 32K TX/RX cache, support 8 independent ports to run at the same time, the module supports 3.3V or 5V power supply to enable users to use in different MCU systems. The communication mode between module and MCU system is SPI protocol, support Up to 80M SPI clock frequency, providing program routines for STM32 and 151 microcontroller client, server, UDP three working modes.
