Description

Interface to any PIC® MCU with SPI interface. Use Microchip's free TCP-IP stack.

Microchip's ENC28J60 is a 28-pin, 10BASE-T stand alone Ethernet Controller with on board MAC & PHY, 8 Kbytes of Buffer RAM and an SPI serial interface. With a small foot print package size the ENC28J60 minimizes complexity, board space and cost. Target applications include VoIP, Industrial Automation, Building Automation, Home Control, Security and Instrumentation.Ethernet Application Design Center

The Microchip Technology Inc. ENC28J60 is a standalone 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.
