ENC28J60T-I/ML - 10BASE-T Ethernet Controller | Microchip
MPN: ENC28J60T-I/ML ✓ AktifENC28J60T-I/ML Ringkasan
A stand-alone Ethernet controller is an interface IC that connects a microcontroller or embedded processor to a wired Ethernet network. The ENC28J60 family provides IEEE 802.3-compatible 10BASE-T operation, hardware packet filtering, programmable receive filtering, and an SPI host interface. This product type sits within interface controllers, communication ICs, semiconductors, and the broader embedded networking hierarchy.
Key features include an integrated 10BASE-T PHY, integrated Ethernet MAC, 8 KB of dual-port buffer SRAM, and a serial SPI interface. The controller is designed for space-constrained embedded equipment where a compact package and a single-network interface simplify board design. Its buffered packet architecture allows the host processor to handle Ethernet traffic without requiring a large external network-memory device.
The ENC28J60T-I/ML uses a 3.3 V supply and is offered in a 28-pin QFN package with a 6 x 6 mm footprint. The manufacturer describes the ENC28J60 as a small-footprint solution intended to reduce complexity, board space, and system cost. The SPI interface also provides a straightforward connection to microcontrollers that have SPI peripherals, while the integrated PHY handles the physical 10BASE-T network connection.
Typical applications include VoIP equipment, industrial automation, building automation, home control, security systems, and instrumentation. In each case, the controller can provide network connectivity to an embedded host processor without requiring a separate Ethernet MAC implementation. It is particularly useful where 10BASE-T connectivity, modest network throughput, and compact board area are more important than fast Ethernet performance.
When designing around the ENC28J60T-I/ML, verify the host processor's SPI voltage and timing requirements, provide the required decoupling and Ethernet magnetics interface specified by the manufacturer, and confirm that the selected package and exposed-pad layout match the PCB footprint. Use the manufacturer datasheet's pin-description and layout tables when assigning nets and defining the physical implementation.

Aplikasi Umum
ENC28J60T-I/ML cocok untuk 6 aplikasis: Industrial Automation Controller, Building Automation Gateway, VoIP Terminal and VoIP Access Device, Home Control and Smart-Device Node, Security and Surveillance Interface, Embedded Instrumentation.
Industrial Automation Controller
The ENC28J60T-I/ML suits compact industrial automation nodes that need wired Ethernet connectivity without a separate Ethernet PHY. Its integrated MAC and PHY reduce the number of network-interface components, while the SPI host connection allows a microcontroller to manage packets through the controller's 8 KB buffer RAM. The 10 Mbps 10BASE-T rate is appropriate for supervisory links, sensor gateways, and machine-control equipment where deterministic low-bandwidth networking is more important than Fast Ethernet throughput. Before deployment, confirm the device's exact temperature grade, isolation requirements, Ethernet magnetics, and grounding arrangement for the installation environment.

Building Automation Gateway
The ENC28J60T-I/ML can provide a low-cost Ethernet uplink for building automation controllers, HVAC interfaces, and access-control nodes. Its integrated 10BASE-T PHY removes the need for a separate physical-layer device, while the compact 28-pin QFN package supports space-conscious terminal electronics. The SPI interface allows a building-control microcontroller to exchange packets without implementing Ethernet framing in host firmware. Because the controller operates at 10 Mbps, designers should account for shared-segment traffic and prioritize device discovery, telemetry, and supervisory traffic rather than high-bandwidth media workloads.

VoIP Terminal and VoIP Access Device
The ENC28J60T-I/ML is suited to compact VoIP terminals and access devices that require a wired 10BASE-T network path but have limited board area. The integrated MAC, PHY, and packet buffer keep the network subsystem compact, while the SPI interface lets the host processor handle packet exchange and application signaling through a serial peripheral. The 10 Mbps Ethernet rate is normally sufficient for properly compressed voice traffic and control traffic. Designers should still assess latency, packet-loss behavior, echo-control requirements, and the available SPI clock and processing bandwidth in the selected host platform.

Home Control and Smart-Device Node
The ENC28J60T-I/ML can add wired Ethernet to a compact home-control hub, security controller, or appliance interface when the product does not require Wi-Fi or Fast Ethernet. Its integrated 10BASE-T PHY and 8 KB buffer simplify the hardware footprint, and the SPI interface is accessible to common embedded microcontrollers. Typical traffic includes status reporting, remote commands, configuration data, and sensor updates, all of which fit comfortably within a 10 Mbps link. The board design should include the manufacturer-recommended Ethernet interface components and provide adequate isolation and surge protection according to the target installation environment.
Direkomendasikan
Security and Surveillance Interface
The ENC28J60T-I/ML can serve as the network interface for a low-bandwidth security panel, access-control reader, or surveillance controller that sends events and receives commands over Ethernet. The integrated MAC and PHY reduce system complexity, while the SPI host link supports packet-driven communication with a security microcontroller. It is appropriate for alarm events, door-state updates, configuration traffic, and periodic telemetry, but it is not intended to transport continuous high-resolution video streams. Use the product primarily as a control-network interface and select a faster Ethernet controller when video transport is a core requirement.
Direkomendasikan
Embedded Instrumentation
The ENC28J60T-I/ML is a practical choice for laboratory and industrial instrumentation that needs remote configuration, status reporting, or data transfer over a wired network. The 10BASE-T interface, integrated PHY, and packet buffer allow an embedded instrument to add networking without requiring a separate Ethernet chipset. Instrumentation designs can use the SPI interface for command processing while the controller manages Ethernet framing and buffering. Because the 10 Mbps link is relatively slow, the instrument should define suitable payload sizes and transfer rates, and the analog or measurement circuitry should be kept appropriately separated from the Ethernet interface and its associated magnetics.

Catatan Desain
Route the ENC28J60T-I/ML Ethernet connection and its associated magnetics according to the manufacturer reference layout. Keep the SPI traces short, provide the specified input and output decoupling close to the device, and confirm the exposed-pad connection and thermal-via pattern from the package drawing before releasing the PCB files.
Treat the Ethernet side as a controlled-impedance, high-speed physical interface even though the negotiated rate is only 10 Mbps. Follow the manufacturer's guidance for the magnetics, termination, return path, and isolation between the PHY and external network connector. Avoid adding long test-point stubs that can disturb the differential signal integrity.
Do not assume that identical package dimensions guarantee that ENC28J60T/ML can replace ENC28J60T-I/ML. Confirm temperature grade, qualification, lifecycle status, and exact pin compatibility in Microchip's ordering information. Also verify the host SPI clock, signal levels, reset behavior, and firmware register expectations before treating the alternate orderable device as interchangeable.
Informasi Konformitas
The available product and distributor records do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. The ENC28J60 is an industrial and commercial interface controller rather than an automotive-qualified device.
