Overview

The ENC28J60-I/ML is a stand-alone 10BASE-T Ethernet controller with an integrated MAC and PHY, designed to serve as an Ethernet interface for any microcontroller with an SPI port. It features 8 Kbytes of dual-port SRAM for packet buffering and hardware-assisted checksum calculation to offload tasks from the host MCU. This 28-QFN device is a popular solution for adding network connectivity to resource-constrained embedded systems.

Why Choose This Part

The integrated PHY and MAC minimize the external component count, requiring only a few passives and a standard RJ45 magnetics jack. It supports full and half-duplex modes and includes a hardware DMA engine for fast data throughput and internal memory management.

Applications

Ethernet-to-Serial Bridges
Connecting legacy RS-232 or RS-485 industrial equipment to local area networks for remote monitoring.
Building Automation Controllers
Providing wired network access to HVAC or lighting controllers in environments where Wi-Fi is unreliable.
VoIP Intercom Systems
Managing audio data transmission over 10Base-T Ethernet in simple point-to-point voice applications.
Remote Sensors
Transmitting sensor telemetry directly to a server via UDP or TCP without requiring a gateway.
