ENC28J60T/ML - 10Mbps SPI Ethernet Controller | Microchip
部品番号: ENC28J60T/ML ✓ 生産中ENC28J60T/ML 概要
An Ethernet controller is an interface IC that manages the lower-level tasks required for a host processor to communicate over an Ethernet network. Within the product hierarchy, the ENC28J60 is a stand-alone Ethernet controller, a network interface controller with integrated media-access control and physical-layer functions. Its combination of an SPI host interface and integrated 10BASE-T PHY reduces the number of external network-interface components required by an embedded design.
Key features include IEEE 802.3-compatible Ethernet operation, 10Mbps networking, an integrated MAC and 10BASE-T PHY, and 8 Kbytes of transmit and receive packet-buffer SRAM. The SPI interface allows register and buffer access from a host controller. The device is supplied in a compact 28-VQFN package with an exposed pad, making it suitable for space-constrained embedded equipment where soldered surface-mount construction is preferred.
The ENC28J60 architecture places the Ethernet MAC and PHY inside one package while retaining packet storage on the controller. This allows a host microcontroller to exchange Ethernet frames through SPI without implementing the complete Ethernet physical and data-link layers itself. According to the Microchip ENC28J60 documentation, the controller meets the relevant IEEE 802.3 requirements for 10BASE-T operation and supports both transmission and reception through the integrated packet buffer.
Typical applications include industrial monitoring equipment, building-automation endpoints, environmental sensors, connected control systems, and compact embedded gateways. The controller is particularly useful when the host processor needs only 10BASE-T connectivity and has limited I/O or processing capacity. SPI-based register access also makes the ENC28J60 practical for platforms where parallel host buses would consume too many pins.
Designers should provide a compliant 3.3 V supply, adequate 10BASE-T magnetic-interface components, and layout that minimizes Ethernet signal integrity and EMI issues. The exposed thermal pad requires suitable PCB copper and thermal-via treatment. Firmware must also handle ENC28J60 initialization, interrupt servicing, descriptor management, and network-driver behavior rather than treating the controller as a protocol-independent plug-in peripheral.
This page consolidates verified manufacturer and distributor information, package details, sourcing data, and replacement guidance. It also separates true same-footprint candidates from cross-package Ethernet alternatives so engineers can evaluate PCB compatibility before making a design change.

主な用途
ENC28J60T/ML の用途: 6 件s: Industrial Sensor Gateway, Building Automation Endpoint, Environmental Monitoring Node, Connected Control Panel, Embedded Network-to-SPI Gateway, Remote Equipment Monitor.
Industrial Sensor Gateway
The ENC28J60T/ML fits industrial sensor gateways that periodically transmit measurements over 10BASE-T Ethernet. Its integrated MAC and 10BASE-T PHY remove the need for a separate Ethernet MAC or PHY, while the SPI host interface preserves MCU pin availability. The 8 Kbytes of packet-buffer RAM support transmit and reception, and the 3.1 V to 3.6 V operating range aligns with a regulated 3.3 V rail. The 28-VQFN package also reduces board area compared with larger leaded controllers. For reliable deployment, use the temperature grade appropriate to the enclosure, provide the required Ethernet magnetic interface, maintain a solid ground and supply return path, and implement a driver that correctly manages ENC28J60 interrupts and packet descriptors.
おすすめ
Building Automation Endpoint
The ENC28J60T/ML is appropriate for compact building-automation endpoints that bridge sensors, controllers, and a 10Mbps Ethernet network. Because the device integrates the Ethernet MAC and 10BASE-T PHY, the host MCU can communicate through SPI while the controller handles the physical Ethernet function. The 8 Kbytes of packet-buffer RAM are sufficient for typical supervisory traffic carrying configuration, status, and alarm data. Its 28-VQFN exposed-pad package suits densely populated equipment, although the thermal pad requires suitable copper area. The 3.1 V to 3.6 V supply range supports conventional 3.3 V power architecture, and the -I ordered alternative may be considered when the installation temperature warrants an industrial grade.
おすすめ
Environmental Monitoring Node
The ENC28J60T/ML can add wired network connectivity to an environmental monitoring node that reports temperature, humidity, air quality, or water-level measurements. The 10Mbps rate exceeds the needs of ordinary telemetry, while the integrated MAC and PHY reduce the external component count and board space required by the network subsystem. SPI host access is useful for MCUs with limited Ethernet peripherals, and the controller’s 8 Kbytes of packet memory accommodates small status and measurement frames. A 3.3 V system rail falls within the device’s 3.1 V to 3.6 V range. Firmware should minimize unnecessary polling, handle link-state changes, and maintain a robust network retry policy rather than assuming uninterrupted Ethernet availability.
おすすめ
Connected Control Panel
The ENC28J60T/ML is suitable for a compact connected control panel that accepts local commands and forwards them to a supervisory Ethernet system. The controller’s integrated 10BASE-T PHY and MAC let a host MCU focus on user-interface and control functions, while the SPI interface provides a compact register and packet-buffer command path. The 10Mbps link is more than sufficient for command traffic and telemetry, and the 28-VQFN package preserves board area for display and input circuitry. Designers should account for the exposed pad during layout and use the 3.1 V to 3.6 V operating range to validate the 3.3 V supply. Network security, authentication, and update mechanisms remain firmware responsibilities.
おすすめ
Embedded Network-to-SPI Gateway
The ENC28J60T/ML is well matched to an embedded gateway that accepts SPI commands from another controller and exchanges them with Ethernet infrastructure. Its stand-alone architecture means the host does not need an integrated Ethernet MAC or PHY, and the 8 Kbytes of dual-port packet-buffer SRAM provides local frame storage. The device operates at 10Mbps from a 3.1 V to 3.6 V supply, matching common 3.3 V embedded platforms. The compact 28-VQFN package helps minimize the gateway footprint, but the exposed pad must be connected to the ground and thermal copper according to the package guidance. The Ethernet magnetic interface and carefully controlled traces remain necessary even though the PHY itself is integrated.
おすすめ
Remote Equipment Monitor
The ENC28J60T/ML can provide a low-cost Ethernet path for remote equipment monitoring where each node must report operating status over a wired network. A microcontroller can use SPI to configure the controller, transmit telemetry, and process receive-buffer events. The integrated MAC and 10BASE-T PHY simplify the hardware compared with a discrete network design, while 10Mbps is more than adequate for diagnostic packets. The 28-VQFN package supports compact unattended equipment, and the 3.1 V to 3.6 V operating range fits a 3.3 V rail. For field reliability, select the required temperature grade, validate the regulator across transient conditions, and include link monitoring, retry limits, and watchdogs in the host firmware.

設計ノート
Treat the Ethernet network path as a controlled-impedance interface rather than a generic low-speed connection. Place the ENC28J60T/ML PHY and the required 10BASE-T magnetic-interface circuitry according to the Microchip hardware guidance, keep the Ethernet-side traces short, and provide a continuous reference plane. Avoid routing digital clocks, SPI signals, and switching-regulator nodes beneath the Ethernet section. The integrated PHY reduces external active components, but it does not remove the need for careful magnetics placement, return-path continuity, and EMI control.
Design the 3.3 V supply for the controller's 160 mA typical current and for transient behavior imposed by the selected Ethernet magnetics and PHY configuration. Place local high-frequency bypass capacitance at the device supply pins and keep supply routes away from the Ethernet-side conductors. The documented operating range is 3.1 V to 3.6 V, so a regulator with suitable transient and thermal performance is required. Confirm the minimum voltage at the IC under load rather than relying only on the nominal 3.3 V rail value.
The 28-VQFN package uses an exposed pad for more than mechanical attachment; it must be connected according to the package drawing and thermal guidance. Provide copper beneath the device, thermal vias where permitted, and adequate solder-paste coverage for reliable assembly. Check the exposed pad's net assignment before PCB release. Because the verified excerpts do not provide thermal resistance or exact pad dimensions, do not substitute generic values; obtain those details from the official package drawing and DS39662C documentation.
Do not assume that every ENC28J60 ordering suffix is interchangeable without checking temperature grade, package, and packaging. ENC28J60T-I/ML is the verified industrial-grade option, while the exact limits for the standard target are absent from the supplied excerpts. In firmware, initialize the PHY and wait for valid link status before transmitting, service interrupts correctly, and handle buffer exhaustion and link changes. A controller that powers up before Ethernet link establishment can create delayed first transmissions or misleading network diagnostics.
コンプライアンス情報
The supplied excerpts do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the distributor pages.
