ENC28J60T/SS - 10Mbps SPI Ethernet Controller | Microchip
MPN: ENC28J60T/SS ✓ AktifENC28J60T/SS Genel Bakış
An Ethernet controller is an interface IC that connects a host processor to a physical Ethernet network. The ENC28J60 belongs to the broader Ethernet interface controller and network interface controller hierarchy, with the SPI interface acting as its connection to the embedded host. Its integrated MAC organizes frame transmission and reception, while the integrated 10BASE-T PHY handles the physical-layer signaling required by a 10BASE-T network.
The primary feature set includes support for 10 Mbps operation, an 8 KB packet buffer, SPI host connectivity, and an integrated MAC and PHY. The 3.1 V to 3.6 V operating supply range places the device in a 3.3 V system environment, while the typical supply-current listing of 160 mA provides a useful baseline for power budgeting. The 28-SSOP package measures 5.30 mm wide by 0.209 inch, supporting compact embedded board layouts without requiring a large QFN footprint.
The architecture makes the ENC28J60T/SS suitable for designs where an MCU or MPU lacks a native Ethernet MAC. The host communicates through the SPI interface, while the controller handles Ethernet framing, address filtering, buffering, and physical-layer communication. Packet filtering reduces the processing burden on the host by allowing selected traffic to be filtered within the controller, and the 8 KB buffer provides temporary storage for frames moving between the SPI host and Ethernet network.
Typical uses include industrial automation controllers, embedded monitoring equipment, access-control terminals, building-network nodes, and IoT gateways with legacy 10BASE-T infrastructure. The part is most appropriate where 10 Mbps is sufficient and the PCB already includes a suitable Ethernet transformer, magnetics, connector, protection network, and controlled-impedance layout.
Designers should allocate a 3.3 V supply with adequate transient margin and account for the listed 160 mA operating current when sizing regulators and copper. The SPI bus must meet the controller's timing requirements, while the Ethernet magnetics and copper path must be laid out according to the manufacturer datasheet. Firmware must also support the ENC28J60 register model, packet filtering, buffer management, and link-state behavior.
This page combines verified manufacturer and distributor data with application guidance, comparison rows, design notes, and sourcing information. It distinguishes confirmed attributes from unavailable details so engineers can identify the documented 10 Mbps, 3.3 V, 8 KB, and 28-SSOP characteristics without relying on an unverified substitute specification.

Tipik Uygulamalar
ENC28J60T/SS için uygundur 6 uygulamas: Industrial Automation Controller, IoT Gateway and Sensor Node, Building Access-Control Terminal, Embedded Network Monitoring, Educational and Prototyping Platform, Legacy 10BASE-T Equipment Upgrade.
Industrial Automation Controller
The ENC28J60T/SS is suitable for industrial automation equipment that needs to report sensor data or accept commands over a 10 Mbps Ethernet link without giving the host MCU a native MAC. Its integrated MAC and PHY reduce the number of network-interface components, while 8 KB of buffer RAM supports frame movement between SPI and the 10BASE-T network. The documented 3.1 V to 3.6 V supply range fits a 3.3 V rail, and the 28-SSOP package preserves board area. A 160 mA listed supply current must be included in the regulator budget. Industrial implementations should also use the exact ordering-temperature option required by the equipment specification and follow the manufacturer layout guidance around Ethernet magnetics, clocking, and decoupling.
Önerilen
IoT Gateway and Sensor Node
The ENC28J60T/SS provides a practical 10BASE-T upgrade path for IoT gateways and wired sensor nodes whose host processor has SPI but no Ethernet MAC. The integrated 10BASE-T PHY and MAC consolidate the network interface into a single 28-SSOP device, and the 8 KB buffer can absorb short bursts of packet traffic while firmware handles filtering and higher-layer processing. Its 10 Mbps rate is appropriate for supervisory traffic, configuration, telemetry, and legacy industrial-network infrastructure rather than high-bandwidth video or bulk transfer. The part's 3.3 V operating range and listed 160 mA supply current simplify integration with embedded 3.3 V systems, although designers must still account for Ethernet magnetics, connector losses, and the copper routing required for reliable 10BASE-T operation.
Önerilen
Building Access-Control Terminal
An access-control terminal can use the ENC28J60T/SS to connect a low-power host processor to a 10 Mbps building network while reducing the external Ethernet component count. The MAC and 10BASE-T PHY are integrated, and 8 KB of packet-buffer memory provides a defined staging area for frames received through the SPI interface. This is useful for systems carrying identification events, configuration updates, and status reports rather than continuous high-volume data. The 3.1 V to 3.6 V supply range operates from a conventional 3.3 V rail, while the 28-SSOP package supports compact terminal electronics. Deployment planning should account for the 160 mA listed device current, Ethernet isolation and surge protection, and the use of the manufacturer-defined package footprint and pin assignments.
Önerilen
Embedded Network Monitoring
The ENC28J60T/SS can add wired Ethernet connectivity to embedded monitoring equipment that collects operating counters, alarms, or environmental readings. A 10 Mbps 10BASE-T link is sufficient for supervisory monitoring, and the controller's packet-filtering capability can reduce unnecessary traffic delivered to the host processor. The integrated MAC and PHY avoid requiring a separate physical-layer device, while 8 KB of buffer RAM supports temporary packet storage. Its 28-SSOP footprint is useful where a larger QFN or connector-heavy interface solution would be difficult to route. The 3.3 V supply range and 160 mA listed current align with many MCU platforms. For reliable deployment, validate the Ethernet transformer selection, keep the copper path controlled, and confirm that firmware includes filtering, link-state, and recovery behavior.
Önerilen
Educational and Prototyping Platform
The ENC28J60T/SS is well suited to microcontroller education and network-prototyping because it gives a student or engineer access to a complete Ethernet controller through SPI. The same 10BASE-T function used in industrial equipment can be demonstrated without a complex external MAC interface, and the documented 8 KB buffer helps illustrate packet reception, filtering, and transmission. Its 3.1 V to 3.6 V operating range makes it convenient for 3.3 V development boards. The 28-SSOP version requires a careful footprint when unlike larger through-hole ENC28J60 boards commonly used in teaching kits. Designers should use the manufacturer pinout and layout data rather than infer connections from an existing module, and should include proper Ethernet magnetics rather than attempting to connect the PHY directly to an unverified network jack.
Önerilen
Legacy 10BASE-T Equipment Upgrade
The ENC28J60T/SS can provide a modern serial host interface while retaining compatibility with existing 10BASE-T copper infrastructure. This makes it relevant for modernization of older monitoring or control equipment that cannot use high-speed Ethernet but still needs a straightforward processor connection. The controller combines its MAC, 10BASE-T PHY, and 8 KB buffer in one package, and the SPI host interface simplifies integration with modern microcontrollers. Its 10 Mbps throughput is suitable for command, status, and low-volume telemetry traffic. The 3.3 V supply range and compact 28-SSOP footprint assist board conversion, but the product must be checked against the original system's isolation, connector, grounding, and cable requirements. Firmware compatibility and exact temperature requirements remain critical upgrade checks.

Tasarım Notları
Design the ENC28J60T/SS supply around its documented 3.1 V to 3.6 V operating range and listed 160 mA current. Place the required local bypass capacitors close to the device power pins and use a regulator that can accommodate the controller, Ethernet magnetics, and associated circuitry without excessive ripple or transient droop. At 3.3 V and 160 mA, the controller input power is approximately 0.528 W by arithmetic; this estimate excludes regulator losses and external network components.
Use the manufacturer package drawing and pinout when laying out the 28-SSOP footprint; the verified excerpts confirm the pin count and package dimensions but do not provide individual pin assignments. Keep the SPI traces away from the Ethernet differential pair and place the local bypass capacitance at the supply pins. Maintain the required copper and component spacing around the Ethernet transformer and connector, and follow the manufacturer hardware guidance for controlled-impedance routing.
Do not treat a controller marked as Ethernet-capable as a complete network connector. The ENC28J60T/SS requires suitable 10BASE-T magnetics, a network jack or connector, and the associated passive network in addition to the IC. Also verify the exact -I temperature-grade ordering option before substitution, because ENC28J60T-I/SS and ENC28J60T/SS share the principal interface ratings but are identified separately in the verified distributor results.
Account for the SPI clock and signal integrity in a design with long host-bus wiring or a slow GPIO implementation. Although the supplied excerpts do not state maximum SPI frequency, they confirm the serial host interface. Use short traces, a defined ground reference, and appropriate series damping if ringing is observed. Keep the Ethernet side isolated from high-current switching paths to reduce common-mode noise and packet-error risk.
Uyumluluk Bilgisi
The supplied verified results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for ENC28J60T/SS. These fields remain unknown rather than being inferred from the manufacturer or package.
