Ⅳ. W5300 register initialization configuration


This system consists of direct addressing mode and 8-bit data bus. The registers of W5300 are composed of mode register, general register and port register. In the W5300 configuration process, you first need to configure the general registers and port registers, and then establish the port connection to complete the initial configuration. In this way, the system can work according to the predetermined settings. W5300 initialization is completed in 3 steps:


1. Set the host interface mode to TCP mode and the bus width to 8 bits.

2. Set basic network information. It mainly requires configuring the MAC address, subnet mask, gateway and source IP address. Once the connection is successfully established, we also need to set the retransmission time and the number of resends. These parameters are used to retransmit data packets when they fail to be sent and to ensure repeated sending of data packets.

3. Define the internal RX/TX memory size and the TX/RX memory size of each SOCKET. W5300 has built-in 16 8K-byte storage units, which are continuously mapped in 128K storage space. This 128K storage space is further divided into transmit memory and receive memory. The internal sending memory and receiving memory are both in units of 8K bytes and distributed in a space of 128K bytes. In addition, the internal TX/RX memory can be reallocated to each SOCKET in 1K byte units within the 0~64K byte space as needed. When the initial setup is completed, the W5300 can respond to Ping requests to verify its network connection status.



Ⅴ. Application areas of W5300


The W5300 is ideally suited for use in many embedded systems, including:

• Embedded server

• Medical monitoring equipment

• Factory and building automation

• Security equipment: DVR, webcam

• Serial to Ethernet: access control, LED display, etc.

• GPIO to Ethernet: Home Network Sensors

• USB to Ethernet: storage devices, network printers

• Parallel interface to Ethernet: copier, POS/microprinter

• Home network equipment: set-top boxes, PVRs and digital multimedia equipment



Ⅵ. How is the network protocol stack of W5300 implemented?


Within the W5300 chip, the implementation of the network protocol stack mainly relies on the following parts:


1. TCP/IP protocol stack

The W5300 integrates the TCP/IP protocol stack internally, which means that it can directly handle network communications based on the TCP/IP protocol. The implementation of the TCP/IP protocol stack is hardware-based and can quickly handle the transmission and reception of network data.


2. Socket interface

The Socket interface is a software interface provided by the W5300. Users can configure the W5300's working mode, send and receive data, and set network parameters through the Socket interface. The implementation of the Socket interface is based on the hardware protocol stack, so users can transmit and receive network data through simple programming.


3. MAC (Media Access Control) layer

The MAC layer is responsible for handling data link layer communications, including the sending and receiving of frames, identification of physical addresses, etc. In the W5300, the functions of the MAC layer are hardware-based, allowing fast and efficient data link layer communication.



Ⅶ. Package of W5300
