The ENC28J60-I/SS is a Microchip Ethernet controller that provides a cost-effective solution for integrating Ethernet functionality into embedded systems. This versatile product is ideal for applications requiring network connectivity such as IoT devices, industrial automation, and home automation. Featuring an integrated MAC and PHY, the ENC28J60-I/SS supports 10BASE-T and 100BASE-TX Ethernet protocols, allowing for high-speed data communication. Its small SSOP package makes it suitable for space-constrained designs, while the single 8-bit host interface minimizes both pin count and software overhead. The ENC28J60-I/SS is designed to interface with a microcontroller through a standard SPI (Serial Peripheral Interface) connection. It offers flexible control and configuration options, including programmable filters for enhanced data packet filtering and CRC generation for data integrity verification. Additionally, the ENC28J60-I/SS supports full-duplex and half-duplex modes, auto-negotiation of network speed and duplex settings, and Wake-on-LAN functionality. It operates on a low power supply voltage of 3.3V, making it efficient for power-sensitive applications. With its reliable performance, compact size, and easy integration, the ENC28J60-I/SS is an excellent choice for adding Ethernet connectivity to your embedded system designs.
