ENC28J60-I/SO 概要
An Ethernet controller is an interface IC that connects a microcontroller or processor to a physical Ethernet network. The MAC manages Ethernet frames and access to the transmit/receive buffer, while the PHY handles the physical-layer signaling. The ENC28J60 combines these functions with an SPI host interface, making it part of the network-controller and interface-IC hierarchy rather than a general-purpose microcontroller.
Verified product information identifies an integrated MAC and PHY, 8 KB of buffer RAM, a 10BASE-T Ethernet interface, and SPI connectivity. The ENC28J60 is designed to operate with a 25 MHz parallel-resonance crystal connected between OSC1 and OSC2, as described in the manufacturer data sheet. A 3.1 V to 3.6 V supply range and -40°C to +85°C operating range are reported by the retrieved distributor data.
Typical uses include microcontroller-based monitoring equipment, industrial control modules, data loggers, laboratory instruments, IoT gateways, and embedded network bridges. The SPI host interface allows the host processor to configure the controller and transfer Ethernet frames, while the integrated PHY reduces the number of external network-interface components.
Designers should provide the required clock network, bypass capacitors, Ethernet magnetics, RJ45 connectivity, and a power supply that stays within the verified 3.1 V to 3.6 V range. Firmware must implement the network stack required by the application because the verified product description identifies the device as a controller with SPI rather than a device with an integrated TCP/IP stack.

主な用途
ENC28J60-I/SO の用途: 6 件s: Industrial Monitoring Gateway, IoT Sensor Hub, Laboratory Data Logger, Embedded Test and Measurement Equipment, Building Automation Controller, Compact Network-to-Serial Bridge.
Industrial Monitoring Gateway
The ENC28J60-I/SO fits industrial monitoring gateways that need a compact 10 Mb/s Ethernet endpoint without a separate MAC or PHY. Its integrated MAC and PHY, 8 KB packet-buffer SRAM, and SPI interface keep the host-side connection simple while the controller handles Ethernet framing. The verified -40°C to +85°C range is useful for equipment operating across industrial temperature conditions, although the enclosure, Ethernet isolation, surge protection, and regulatory testing remain system-level requirements. The host processor must provide the required network firmware.
おすすめ
IoT Sensor Hub
The ENC28J60-I/SO is suitable for IoT sensor hubs that aggregate local measurements and expose them over a wired 10BASE-T network. Its 3.1 V to 3.6 V operating range aligns with many embedded 3.3 V systems, while SPI allows a microcontroller to connect without a parallel bus. The integrated PHY reduces board-level network-interface complexity, and 8 KB of buffer RAM supports packet buffering for burst traffic. The design must still include Ethernet magnetics, RJ45 connectivity, suitable clock components, and host-side networking software.
おすすめ
Laboratory Data Logger
For laboratory instruments and data loggers, the ENC28J60-I/SO provides a compact Ethernet path for transferring measurement records to a host computer. The 10 Mb/s rate is generally appropriate for configuration, status, and moderate data files, while the integrated MAC and PHY reduce the number of external interface components. Its SPI host connection is convenient for microcontrollers with limited pin counts. Use a stable 25 MHz clock arrangement and a carefully designed Ethernet front end to preserve data integrity and minimize packet loss.
おすすめ
Embedded Test and Measurement Equipment
The ENC28J60-I/SO can add network access to embedded test and measurement equipment where a full Fast Ethernet PHY is unnecessary. Its integrated 10BASE-T PHY and MAC are useful when an instrument needs remote control, status reporting, or configuration transfer over a wired network. The 3.3 V supply domain and SPI interface support compact embedded platforms, but designers should account for grounding, isolation, connector mechanics, and electromagnetic compatibility. Verify the manufacturer’s layout guidance before routing Ethernet signals.
おすすめ
Building Automation Controller
The ENC28J60-I/SO is appropriate for building-automation controllers that distribute sensor, actuator, and diagnostic information over a wired Ethernet segment. The integrated controller and PHY simplify the network endpoint, while 8 KB of packet RAM provides a dedicated transmit/receive buffer. The verified industrial temperature range supports equipment in controlled environments, but building systems may require isolation, surge protection, cable fault handling, and regulatory compliance beyond the IC itself. Firmware selection is important because the ENC28J60 does not present itself as a TCP/IP-offload device.
おすすめ
Compact Network-to-Serial Bridge
The ENC28J60-I/SO can serve as the Ethernet side of a compact network-to-serial bridge built around a microcontroller. SPI transfers frames between the Ethernet controller and the host, allowing legacy serial equipment to receive commands or report data over Ethernet. Its 10 Mb/s capability is sufficient for supervisory traffic and many control messages, while the integrated PHY reduces the external component count. The bridge should include host-side packet processing, Ethernet magnetics, RJ45 protection, and a defined recovery strategy for cable or network faults.

設計ノート
Design the ENC28J60-I/SO supply rail within the verified 3.1 V to 3.6 V range. The retrieved distributor data lists 160 mA supply current, but that value should not be treated as a complete worst-case system budget until the manufacturer’s operating conditions and Ethernet-drive requirements are checked. Place bypass capacitors close to the device supply pins and account for startup current from the Ethernet magnetics and attached cable.
Use the manufacturer’s recommended Ethernet layout rather than treating the PHY as a generic digital chip. Keep the 25 MHz crystal and its load components close to OSC1 and OSC2, route the Ethernet differential pair as a controlled impedance path, and provide the required Ethernet magnetics and RJ45 protection. The supplied data confirms the clock requirement and integrated PHY, but component values and exact routing dimensions must be taken from the official data sheet.
Do not substitute a 5 V-only Ethernet front end or assume that a related ENC28J60 order code is automatically drop-in compatible. The verified target is a 3.1 V to 3.6 V, 28-pin SOIC device, and the supplied cross-reference results show related SOIC, SSOP, and SSOP variants. Confirm pin names, package dimensions, temperature grade, oscillator arrangement, and firmware expectations before releasing a replacement to production.
Keep the controller’s thermal environment within the verified -40°C to +85°C operating range and provide copper area appropriate to the SOIC footprint. The supplied data does not provide a verified thermal resistance or power-dissipation curve, so do not invent a junction-temperature estimate. Validate the assembled board across ambient temperature, Ethernet-cable insertion, and worst-case host activity using the manufacturer’s absolute-maximum and electrical-characteristic limits.
コンプライアンス情報
The supplied verified product and distributor snippets do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The Ethernet compatibility designation is IEEE 802.3 compatible, but that statement is not a component environmental-compliance claim.
