KSZ8567STXI - 7-Port Managed 10/100 Ethernet Switch | Microchip
MPN: KSZ8567STXI ✓ AktifKSZ8567STXI Genel Bakış
An Ethernet switch is a Layer 2 network-semiconductor device that receives Ethernet frames on one port and forwards them toward the appropriate destination port using MAC-address tables. A managed switch adds configuration, monitoring, traffic prioritization, timing, and recovery functions that distinguish it from a basic unmanaged switch. The KSZ8567 integrates seven-port switching, five copper PHYs, a host-management interface, and automotive-oriented robustness into one device.
Five of the seven ports include 10/100BASE-T copper PHYs. The switching fabric supports full-duplex 100 Mbit/s copper links for local industrial, automotive, communications, and embedded network equipment. The integrated PHY reduces external magnetics and copper-interface component count, while the I2C and SPI interfaces allow a host controller to configure registers, monitor port status, and implement network-management functions.
The KSZ8567 family includes fault-recovery, IEEE 1588 v2 precision-time support, Audio Video Bridging, Energy Efficient Ethernet, Wake-on-LAN, and QoS capabilities. IEEE 1588 v2 timing can support synchronized traffic in systems requiring precise time distribution. AVB and QoS are useful when deterministic traffic must share Ethernet links with less timing-critical network traffic. EEE can reduce link energy where supported by the complete network, while LinkMD+ provides cable diagnostics that simplify commissioning and fault isolation.
Typical applications include automotive Ethernet gateways, industrial control systems, networked sensors, factory equipment, embedded service interfaces, and compact Ethernet aggregation units. The 128-TQFP exposed-pad package supports substantial copper-based thermal dissipation on multilayer PCBs, but thermal performance still depends on the pad, vias, copper area, and ambient conditions.
For a new design, verify the complete pin assignment, reference clock requirements, magnetic-component recommendations, register initialization, and layout guidance in the manufacturer datasheet. Preserve the exposed-pad land pattern and connect it to the intended ground plane according to the package drawing. When assessing a second source, confirm pinout and firmware behavior in addition to the number of ports; a functionally similar Ethernet component is not automatically a drop-in replacement.
This page combines manufacturer device information, package and interface details, commercial sourcing guidance, and engineering-focused replacement criteria. It helps engineers identify whether the KSZ8567STXI matches a seven-port managed-switch requirement before beginning PCB layout and software configuration.

Tipik Uygulamalar
KSZ8567STXI için uygundur 6 uygulamas: Automotive Ethernet Gateway, Industrial Control Ethernet Aggregation, Networked Sensor Edge Device, Factory Equipment Communication Hub, Audio Video Network Endpoint, Power and Building Automation Controller.
Automotive Ethernet Gateway
The KSZ8567STXI fits an automotive Ethernet gateway requiring seven managed switch ports and five integrated 10/100BASE-T PHYs. Its design target to exceed AEC-Q100 Grade 2 requirements over -40°C to +105°C supports extended-temperature vehicle electronics, while IEEE 1588 v2, AVB, and QoS support timing-sensitive network traffic. The host controller can use I2C or SPI for configuration and status monitoring. Design effort must include exact pin assignment, EMC implementation, cable and magnetic-component selection, exposed-pad thermal management, and automotive validation of the complete module.
Önerilen
Industrial Control Ethernet Aggregation
The KSZ8567STXI is suitable for industrial controllers that must aggregate several 10/100 Mbit/s links while retaining local management. Seven switch ports reduce the need for discrete switching components, and five integrated PHYs simplify board partitioning and connector implementation. QoS helps separate operational traffic classes, while fault recovery supports dependable link operation. The -40°C to +105°C design target is useful in factory equipment, but engineers must still validate EMC margins, isolation requirements, grounding, thermal performance, and the industrial network-loading profile in the final enclosure.
Önerilen
Networked Sensor Edge Device
The KSZ8567STXI can serve as the Ethernet aggregation center in a networked sensor edge device that connects controllers, sensors, and service interfaces over 10/100 links. Its managed Layer 2 operation provides a more structured alternative to a collection of isolated PHYs, while WOL and fault-recovery functions can improve maintenance behavior. EEE may reduce link energy when the complete network supports it. Choose PHY magnetics, magnetics-integration strategy, and port configuration according to cable reach and EMC requirements rather than treating all copper links as identical.
Önerilen
Factory Equipment Communication Hub
The KSZ8567STXI fits factory equipment hubs that connect programmable controllers, remote I/O, vision equipment, and service interfaces without requiring multiple external switch chips. Seven ports and integrated 10/100BASE-T PHYs create a compact managed Ethernet node, while QoS and IEEE 1588 v2 can help organize traffic that differs in timing importance. The implementation should include careful isolation and surge protection planning, validated magnetic components, robust ground-plane design, and firmware configuration that matches the equipment's expected traffic pattern.
Önerilen
Audio Video Network Endpoint
The KSZ8567STXI is suitable for an AVB-capable audio or video endpoint that connects networked media nodes over 10/100 Ethernet. AVB and QoS features provide mechanisms for prioritizing time-sensitive media traffic, while IEEE 1588 v2 supports precise time synchronization across the network. The seven-port architecture allows local aggregation without a separate switching device in suitable designs. Validate the complete synchronization topology, traffic reservation behavior, host timing capability, PHY configuration, and endpoint latency against the target AVB system before production release.
Önerilen
Power and Building Automation Controller
The KSZ8567STXI can support a building or industrial automation controller that connects room controllers, lighting systems, access equipment, and service interfaces over a managed Ethernet segment. Seven ports provide room for several fieldbus-to-Ethernet bridges and local service connections, while link diagnostics can assist commissioning. WOL can support remote maintenance access, and EEE can lower link activity when traffic is intermittent. Because the 10/100 capability limits high-bandwidth aggregation, planners should use multiple switch tiers or higher-speed upstream links when required.

Tasarım Notları
Treat the exposed pad as the primary thermal path in the 128-TQFP-EP package. Follow the manufacturer land pattern, place the recommended thermal-via array beneath the pad, and provide uninterrupted ground-plane copper beneath the via field. Do not assume that a via array alone guarantees acceptable junction temperature: actual performance also depends on multilayer-board construction, copper area, adjacent heat sources, airflow, and ambient temperature.
Assign every power, ground, management, clock, and Ethernet signal pin from the manufacturer pin-description table before routing. Keep the exposed-pad ground connection short, place its thermal vias close to the pad, and preserve the manufacturer-recommended copper geometry around high-speed interfaces. A generic 128-pin symbol is not sufficient because the exposed pad and no-connect positions must match the exact package drawing.
Route Ethernet pairs as controlled-impedance differential pairs and follow the manufacturer's layout guidance for PHY connections, clocking, grounding, and copper interfaces. Account for connector launch geometry, return paths, isolation boundaries, and the selected magnetic-component implementation. Validate the finished board with the intended 10/100 link partners because switching and PHY features can expose marginal edge-rate or return-path problems not visible in a schematic review.
Do not treat KSZ8842, DP83867, KSZ9477, or KSZ9567 as automatic replacements merely because they perform related Ethernet functions. A drop-in choice requires the same package, pin-to-pin assignment, power rails, clocking, interface protocol, and register behavior. Record the exact suffix and packing configuration in the bill of materials, and obtain manufacturer confirmation before using KSZ8567R on a released production PCB.
