ENC28J60
Description
The Microchip Technology Inc. ENC28J60 is a stand-
alone Ethernet controller with an industry standard
Serial Peripheral Interface (SPI鈩?. 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.
