The Enc28j60 Arduino Ethernet Module LAN Network Module is a board which contains an Ethernet port and converts Ethernet input into SPI. The board is based on Microchip’s ENC28J60 integrated circuit and it can be used to provide internet connectivity to microcontroller systems like Arduino boards over Ethernet.

Since the board is small in size and it supports SPI, it is applicable to a variety of projects.

The ENC28J60 Arduino Ethernet Module consists of seven major functional blocks:

1. An SPI interface that serves as a communication channel between the host controller and the ENC28J60.

2. Equips control registers for controlling and monitoring the ENC28J60.
3. A dual port RAM buffer for received and transmitted data packets.
4. An arbiter to control the access to the RAM buffer when requests are made from DMA, transmit and receive blocks.
5. The bus interface that interprets data and commands received via the SPI interface.
6. The MAC (Medium Access Control) module that implements the IEEE 802.3 compliant MAC logic.
7. The PHY (Physical Layer) module that encodes and decodes the analog data that is present on the twisted-pair interface.
