The ENC28J60 is a board with an Ethernet port and an Ethernet input that is connected to SPI. It’s an Ethernet controller with a serial peripheral interface that may be used on its own. ENC28J60 makes use of the new ENC28J60 host microchip to handle the majority of network protocol requirements. As a result, the board is immediately linked to most microcontrollers through a conventional SPI interface with a transmission rate of up to 25 MHz. This is the easiest method for connecting a LAN network to the microcontroller, depending on the project and product. These modules work with any microcontroller that runs on 3v or 5v. Over Ethernet, it connects microcontroller systems like Arduino boards to the internet. This module has half-duplex and duplex modes, as well as configurable padding and a CRC.. It also provides programmable automatic rejection of erroneous packets and programmable automatic retransmit on collision.
The ENC28J60 is a 28-pin 10BASE-T Ethernet controller featuring on-board MAC and PHY, 8 Kbytes of Buffer RAM, and an SPI serial interface. With its tiny footprint and compact dimensions, the ENC28J60 reduces complexity, board space, and cost. As a result, VoIP, Industrial Automation, Building Automation, Home Control, Security, and Instrumentation are among the intended applications. The ENC28J60 Ethernet Module is a Serial Peripheral Interface (SPI) that is widely used in the industry (SPI). It may be used as an Ethernet network interface for any SPI controller. Between the host controller and the ENC28J60, the SPI interface acts as a communication route. Furthermore, the bus interface decodes data and commands sent through the SPI interface.
