ماژول شبکه ENC28J60

The ENC28J60 is a stand-alone Ethernet controller with an industry-standard Serial Peripheral Interface (SPI). It is designed to serve as an Ethernet network interface for any controller equipped with SPI.

The ENC28J60 meets all of the IEEE 802.3 specifications. It incorporates a number of packet filtering schemes to limit incoming packets. It also provides an internal DMA module for fast data throughput and hardware-assisted checksum calculation, which is used in various network protocols. Communication with the host controller is implemented via an interrupt pin and the SPI, with clock rates of up to 20 MHz. Two dedicated pins are used for LED link and network activity indication.

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

2. Control Registers are used to control and monitor 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.
