ENC28J60 Ethernet Module is based on Microchip’s ENC28J60 stand-alone 10Base-T Ethernet controller. 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. The ENC28J60 meets all of the IEEE 802.3 specifications. It also provides an internal DMA module for fast data throughput and hardware assisted checksum calculation, which is used in various network protocols. Communication with the host controller is implemented via an interrupt pin, if required, and the SPI, with clock rates of up to 20 MHz. It has dedicated pins for LED link and network activity indication. The module includes RJ45 Ethernet connector with built-in magnetic and link indicator LEDs. The onboard low drop voltage regulator supplies stable voltage to the Ethernet controller. It is an ideal device for applications involving Home/Office Automation, Remote Diagnostics systems, Industrial equipments, Security Systems and Robotics as well.

Note:
For interfacing ENC28J60 based Ethernet module with the host microcontroller requires fair amount of expertise. Microchip has developed a free, configurable TCP/IP stack for its own microcontroller portfolio. It also has a lot of application notes related to stack which can be accessed through Microchip website. For any further information on using the Microchip stack please contact microchip technical support. All the Ethernet modules are carefully tested for the performance.
