OVERVIEW

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.

Ethernet Controller Features

• IEEE 802.3 compatible Ethernet controller

• Integrated MAC and 10BASE-T PHY

• Supports one 10BASE-T port with automatic polarity detection and correction

• Supports Full and Half-Duplex modes

• Programmable automatic retransmit on collision

• Programmable padding and CRC generation

• Programmable automatic rejection of erroneous packets

• SPI Interface with clock speeds up to 20 MHz

Buffer

• 8-Kbyte transmit/receive packet dual port SRAM

• Configurable transmit/receive buffer size

• Hardware-managed circular receive FIFO

• Byte-wide random and sequential access with auto-increment

• Internal DMA for fast data movement

• Hardware assisted checksum calculation for various network protocols

Medium Access Controller (MAC) Features

• Supports Unicast, Multicast and Broadcast packets

• Programmable receive packet filtering and wake-up host on logical AND or OR of the following:

- Unicast destination address

- Multicast address

- Broadcast address

- Magic Packet™

- Group destination addresses as defined by 64-bit hash table

- Programmable pattern matching of up to 64 bytes at user-defined offset

Physical Layer (PHY) Features
