ENC28J60 is a low-cost Ethernet LAN Network Module equipped with ENC28J60 integrated circuit to handle most of the network protocols requirements meeting all the IEEE 802.3 standards. ENC28J60 module has an ability to connect directly to most of the microcontrollers with a standard SPI interface. The module has 25MHZ crystal with Ethernet RJ45 Jack HR911105A and integrated LEDs.
It is widely used with the small-sized embedded systems due to its simple and easy connections and low cost. The module can offer a maximum speed of 10 MBPS. It supports both full and half-duplex modes. ENC28J60 module outperforms other devices in web servers such as communication convertor and instrument, transaction terminal, IP telephone, and other Ethernet applications.
