Description

The Microchip Technology Inc. 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

microcontroller equipped with SPI.

The ENC28J60 meets all of the specifications for

IEEE 802.3. It incorporates a number of packet filtering

schemes to limit incoming packets. It also provides

internal DMA for fast data throughput and support for

hardware assisted IP checksum calculation.

Communication

with

the

microcontroller

is

implemented via SPI, with data rates up to 10 Mbit/s.

Dedicated pins are used for LED link and activity

indication and for transmit and receive interrupts.
