Developing an Ethernet Interface Using a General Purpose Microcontroller and Ethernet Controller for Power Amplifier

With the rising trend, internet has become more widespread. A number of devices with microcontroller have been widely used in the industrial field. As all devices don't have the internet interface, the data from them cannot be transmitted in the network. Considering the technological development in the market place, the power amplifier with Ethernet interface options plays a significant role in monitoring and controlling operation in real time. For this purpose the power amplifier needs a physical communication port with the network. This paper presents the design and implementation of such Ethernet interface for power amplifier with microcontroller. The power amplifier communicates with the Ethernet controller through SPI (serial peripheral interface) port. The Ethernet controller ENC28J60 is the main element manufactured by the Microchip company, according to IEEE 802.3 standards along with the MAC and PHY modules. The Ethernet controller ENC28J60, an RJ45 connector and few passive components along with general purpose microcontroller is connected to the network and it works at a speed of 64Mbps.
