ENC28J60 (RJ45)

ENC28J60 Ethernet Controller Module with integrated RJ45 interface, designed to deliver compact, reliable network connectivity for embedded systems. The module implements a 10BASE-T Ethernet interface and is intended for applications that require cost-effective wired LAN communication while minimizing PCB footprint.

• 10BASE-T Ethernet interface for stable data transmission
• SPI communication for straightforward integration with microcontrollers
• Supports full-duplex and half-duplex operation for flexible network configurations
• 8 KB buffer memory to handle incoming and outgoing packets efficiently
• Operates at 3.3V supply voltage compatible with low-power embedded systems

By integrating the RJ45 connector directly on the module, the ENC28J60 (RJ45) simplifies hardware design and reduces overall PCB size compared with modules that require a separate connector. The SPI interface provides an efficient serial link to host controllers, simplifying firmware integration compared with parallel bus approaches. The module’s buffer size and duplex capabilities are well suited to single-chip Ethernet controller applications.

Network Offload and Standards Compliance

The ENC28J60 includes hardware features that reduce host CPU workload, including automatic packet filtering and checksum calculation. Its integrated MAC and PHY layers comply with IEEE 802.3 standards, ensuring compatibility with standard Ethernet networks and predictable interoperability across diverse environments. These characteristics make the module appropriate for embedded projects that need a compact, standards-compliant Ethernet interface while keeping system complexity and board area to a minimum.
