Working Principles

The ENC28J60T/SS is an Ethernet controller that enables microcontrollers to connect to an Ethernet network. It operates using the Serial Peripheral Interface (SPI) protocol, allowing easy integration with various microcontroller platforms. The controller handles the transmission and reception of Ethernet frames, implementing protocols such as TCP/IP, UDP, ICMP, ARP, and IGMP.

When a microcontroller wants to send data over the network, it writes the data into the transmit buffer of the ENC28J60T/SS. The controller then takes care of encapsulating the data into Ethernet frames and transmitting them over the network. On the receiving side, the controller receives incoming Ethernet frames, extracts the data, and stores it in the receive buffer for the microcontroller to retrieve.

Detailed Application Field Plans

The ENC28J60T/SS finds applications in various fields, including:

  1. Internet of Things (IoT) devices
  2. Home automation systems
  3. Industrial automation and control
