W6300-L Visão geral

The WIZnet W6300-L is a hardwired TCP/IP Ethernet controller chip that integrates a dual IPv4/IPv6 protocol stack in hardware, delivering 10/100 Mbps Ethernet performance for embedded systems in an LQFP-48-EP (7x7 mm) surface-mount package.

A hardwired TCP/IP controller is a type of offload engine (TOE - TCP/IP Offload Engine) in the broader hierarchy of network interface ICs. Unlike software stacks running on a host MCU, a hardware protocol stack offloads TCP, UDP, ICMP, ARP, and related processing from the main processor, so even a small 8-bit MCU can implement reliable network connectivity with minimal firmware overhead and deterministic timing. This makes the category essential for industrial automation, IoT gateways, and embedded networking nodes.

Key features of the W6300-L include the dual IPv4/v6 hardware stack, which sets it apart from WIZnet's earlier IPv4-only devices; multiple independent hardware sockets for simultaneous connections; a high-speed host interface for fast data throughput; and low-power operation modes for energy-sensitive designs. According to the WIZnet product page, the chip combines high-speed Ethernet performance with advanced power efficiency.

Technically, the W6300 continues WIZnet's well-established W-series architecture: socket registers, internal TX/RX buffers, PHY, and MAC are all integrated, so designers need only an external RJ45 magnetics jack and a host MCU to complete the network node. The hardware stack eliminates porting, memory-footprint, and real-time concerns associated with software TCP/IP stacks such as lwIP.

Typical applications include industrial automation and factory networking, IoT gateways bridging field devices to cloud backends, and embedded equipment requiring IPv6 readiness for modern network infrastructure.

For design consideration, verify host-interface timing against your MCU's SPI or bus clock, and follow the WIZnet reference schematic for magnetics, crystal, and decoupling placement to guarantee PHY signal integrity.

Aplicações típicas

W6300-L é adequado para 6 aplicaçãos: Industrial Automation Networking, IoT Gateways, Embedded Equipment Ethernet Ports, Smart Building and HVAC Controllers, Security and Surveillance Network Interfaces, Energy and Smart Metering Backhaul.

🏭

Industrial Automation Networking

The W6300-L fits industrial automation nodes because its hardwired TCP/IP stack delivers deterministic, jitter-free TCP/UDP processing independent of host MCU load - a property software stacks cannot guarantee on small processors. With dual IPv4/IPv6 support, 10/100 Mbps throughput, and multiple hardware sockets, a single chip can sustain simultaneous PLC, SCADA, and diagnostic connections. The chip is placed between the host MCU and an RJ45 magnetics jack; the hardware stack offloads all protocol handling, freeing MCU cycles for control logic. The LQFP-48-EP package and RoHS compliance support standard industrial SMT assembly.

🧩

IoT Gateways

IoT gateways bridge constrained field devices to cloud backends, and the W6300-L suits this role with its dual IPv4/IPv6 hardware stack - increasingly mandatory as carriers and enterprises migrate to IPv6. The high-speed host interface feeds sensor aggregates upstream at 10/100 Mbps, while multiple hardware sockets allow simultaneous MQTT, HTTP, and OTA-update channels without software stack memory pressure. Power-efficiency modes benefit gateways on auxiliary or solar power. Designers typically connect the W6300 to the gateway MCU's high-speed interface and an external magnetics RJ45, keeping the BOM to chip plus jack.

🔧

Embedded Equipment Ethernet Ports

Adding a network port to embedded equipment (test instruments, kiosks, building controllers) is the classic WIZnet TOE use case, and the W6300-L minimizes engineering effort: no software TCP/IP stack to port, no lwIP memory tuning, no real-time pitfalls. The integrated MAC and PHY reduce BOM count versus discrete solutions - only magnetics, crystal, and decoupling are added. The 10/100 Mbps rate comfortably serves configuration web servers, firmware updates, and telemetry. Because the stack is in silicon, even an 8-bit or entry-level Cortex-M0 host can offer full networking, shortening development cycles substantially.

💡

Smart Building and HVAC Controllers

Building automation controllers benefit from the W6300-L's IPv6 readiness, since municipal and enterprise networks increasingly mandate IPv6 addressing for permanently installed equipment. The hardware sockets allow a controller to serve BACnet/IP-style messaging, web dashboards, and remote diagnostics concurrently. Deterministic hardware protocol processing avoids the variable latency of software stacks, which matters for scheduled control loops reporting over the network. The chip sits between the controller MCU and RJ45 magnetics; power-efficiency modes reduce standby draw in always-installed but lightly loaded devices, supporting green-building energy targets.

🎥

Security and Surveillance Network Interfaces

Security panels, access controllers, and NVR auxiliary interfaces need reliable always-on connectivity, and the W6300-L provides it with a hardware TCP/IP stack immune to software-stack crashes or memory leaks - an availability advantage for security-rated equipment. Dual IPv4/IPv6 support satisfies modern campus networks, and multiple hardware sockets let a device maintain a monitoring heartbeat, event-upload channel, and local configuration server simultaneously at 10/100 Mbps. The integrated PHY plus external magnetics keeps the analog front end short and clean on the PCB, easing EMC compliance in metal-enclosure security hardware.

⚡

Energy and Smart Metering Backhaul

Smart meters and energy gateways require long-life, low-maintenance connectivity, and the W6300-L's hardwired stack delivers protocol reliability without firmware-stack maintenance over a 15+ year service life. IPv6 support is frequently specified in utility network rollouts, and the W6300-L provides it natively in hardware. Power-efficiency modes reduce standby consumption between metering intervals. The 10/100 Mbps interface handles DLMS/COSEM-over-TCP or MQTT telemetry easily, and the multiple hardware sockets allow separate channels for metrology data streams and remote firmware campaigns, isolating update traffic from measurement reporting.

What is the W6300-L?
The W6300-L is a WIZnet hardwired TCP/IP Ethernet controller chip with a dual IPv4/IPv6 hardware protocol stack. It delivers 10/100 Mbps Ethernet performance, integrates the MAC and PHY, and comes in an LQFP-48-EP (7x7 mm) package. Because the TCP/IP stack is implemented in silicon, a host MCU needs only simple register access to create network sockets, avoiding the memory and complexity of software stacks such as lwIP.
What is the price of W6300-L?
Pricing for the W6300-L starts at approximately $5.20 for a single unit, dropping to around $3.12 per unit at 1000-piece quantities as of 2026-10-19. Pricing varies by distributor; Octopart lists two distributors (DigiKey and Mouser) carrying stock. For volume quotes above 1000 pieces, contact XAIPART or an authorized WIZnet distributor such as JLink Technology for a formal quotation.
Where to buy W6300-L online?
You can buy the W6300-L from DigiKey (part page 29198027), Mouser, or via XAIPART, which offers tiered pricing and quote support. JLCPCB Assembly also stocks it under part number C9900259542 for turnkey assembly. All major distributors list the part as available with same-day shipping from stock as of 2026-10-19, according to DigiKey's product listing.
Does the W6300 support IPv6?
Yes, the W6300 natively supports both IPv4 and IPv6 through its dual hardware protocol stack. This is a key differentiator from WIZnet's earlier IPv4-only chips such as the W5500 and W5100S, and makes the W6300 suitable for networks migrating to IPv6, as required in many industrial and public-infrastructure deployments today.
What is the difference between W6300 and W5500?
The main difference is the protocol stack: the W6300 has a dual IPv4/IPv6 hardware stack, while the W5500 supports IPv4 only. The W6300 also offers a higher-speed host interface and improved power efficiency. Both integrate MAC+PHY with hardware sockets, but they are not pin-to-pin compatible in all package options, so the W5500 is not a drop-in replacement - PCB layout and firmware register interfaces must be verified against the WIZnet datasheets.
What is the best drop-in replacement for W6300-L?
The closest drop-in replacement for the W6300-L is the W6300 itself, which shares the same die and LQFP-48-EP (7x7 mm) footprint and differs only in packaging/ordering designation. No cross-brand pin-compatible equivalents are documented in available web data as of 2026-10-19. For new designs needing only IPv4, the W5500 offers a lower-cost alternative but requires PCB redesign because it is not footprint-compatible.
Which WIZnet Ethernet chip should I choose for IPv6 networks?
Choose the W6300-L when your application must support IPv6, such as smart-grid, building automation, or government infrastructure projects with IPv6 mandates. Its dual IPv4/IPv6 hardware stack handles both address families natively. If IPv4-only is sufficient and cost is the priority, the W5500 or W5100S are adequate. Choose W6300 when you also need a high-speed host interface for throughput above what the W5500's SPI offers.
Is the W6300-L suitable for industrial automation applications?
Yes, the W6300-L is explicitly targeted at industrial automation by WIZnet. The hardwired protocol stack provides deterministic, jitter-free TCP/UDP processing unaffected by software stack latency, an important property for factory networking and PLC communications. The 10/100 Mbps PHY, multiple hardware sockets, and robust LQFP-48-EP package support industrial environments; designers should confirm the exact operating temperature grade in the datasheet for their specific thermal environment.
What can replace W6300-L if it becomes unavailable?
Currently the only documented drop-in replacement for the W6300-L is the W6300, which shares the same silicon and package footprint. Because no cross-brand pin-compatible Ethernet TOE in an LQFP-48-EP is documented in available web sources, engineers facing long-term supply risk should consider a second-source strategy: design the PCB to accept either the W6300 footprint or a W5500-based layout, or maintain buffer stock of the W6300-L.
Is there a cross-brand equivalent for the W6300-L?
No cross-brand drop-in equivalent for the W6300-L was found in available cross-reference web data as of 2026-10-19. Functionally similar TCP/IP offload chips exist from other vendors, but none share the LQFP-48-EP footprint with pin-to-pin compatibility and the dual IPv4/IPv6 hardware stack. Any cross-brand substitution therefore requires PCB rework and firmware changes, and should be validated against the respective datasheets before committing.
Where can I download the W6300 datasheet PDF?
The W6300 datasheet is available from the WIZnet Document System at docs.wiznet.io under Product/Chip/Ethernet/W6300/datasheet. The same portal hosts the pinout diagrams, register maps, and reference schematics. XAIPART also links the datasheet directly on this product page. Always verify you are reading the latest revision on the official WIZnet documentation site before starting a design.
Where can I find the W6300-L pinout?
The W6300-L pinout is documented in the WIZnet W6300 datasheet on the WIZnet Document System (docs.wiznet.io). The 48-pin LQFP-EP package pin definitions include power, PHY (TX/RX pairs to magnetics), crystal, reset, and host interface pins. Because pin naming and multiplexing vary with the selected host interface mode, consult the datasheet pin description table for your specific configuration rather than relying on generic LQFP-48 layouts.
What are the key specifications of W6300-L engineers should know?
The W6300-L is a 10/100 Mbps hardwired TCP/IP Ethernet controller with a dual IPv4/IPv6 hardware stack, integrated MAC and PHY, multiple hardware sockets, and a high-speed host interface, housed in an LQFP-48-EP (7x7 mm) package. It offers advanced power-efficiency modes and is RoHS compliant. These specs make it suited for industrial automation, IoT gateways, and embedded networking where deterministic protocol handling and IPv6 readiness matter more than raw gigabit throughput.
Is the W6300-L in stock and what is the lead time?
Yes, the W6300-L is listed as in stock at DigiKey and Mouser with same-day shipping according to their product pages as of 2026-10-19. Octopart confirms two distributors carrying inventory. Standard lead time for in-stock quantity is effectively immediate; for large volumes beyond distributor stock, WIZnet authorized distributor JLink Technology quotes production lead times, typically replying within one business day.
Is W6300-L the same as W6300?
The W6300-L is the same silicon as the W6300; the suffix designates the packaging and ordering variant, in this case RoHS-compliant LQFP-48-EP in tray or reel form. Both parts offer identical dual IPv4/IPv6 hardware stacks, 10/100 Mbps Ethernet, and the same footprint, so they are electrically and mechanically interchangeable in any PCB design. Always order the exact suffix your production process requires (reel vs. tray).

Guia de seleção

Choose the W6300-L when your design requires IPv6 support, deterministic networking without a software stack, or higher host-interface throughput than the W5500 provides - typical for IoT gateways, industrial nodes, and any equipment destined for IPv6-mandated networks. Choose the W5500 if IPv4-only suffices and lowest cost and lowest power are priorities; it is a well-proven part but not pin-compatible, so switching later means a PCB respin. Choose the W5100S for very cost-sensitive, simple IPv4 endpoints. Choose the W6300 over the W6300-L only for the packaging suffix your production line needs (reel vs tray); the silicon is identical. For all options, budget development time to the WIZnet register maps - the W6300 is not a firmware drop-in for W5500 code.

  • Software-stack-free determinism vs MCU software TCP/IP (vs Generic MCU + lwIP software stack)

Notas de projeto

Place the W6300-L's PHY side as close to the RJ45 magnetics jack as practical and keep TX/RX pairs as matched-length differential traces over a continuous ground plane. Follow the WIZnet reference schematic in the official datasheet for magnetics selection, 49.9-ohm PHY termination resistors, and decoupling capacitor placement at each VDD pin. Add a solid keep-out under the crystal to keep stray capacitance within spec.

Provide clean, well-decoupled supply rails per the datasheet power pin grouping; the integrated PHY is sensitive to supply ripple, which shows up as Ethernet eye-diagram degradation. Estimated: budget roughly 200-300 mA at 3.3 V for active link operation as a starting point, then confirm against the datasheet current-consumption table for your exact PHY mode and speed before finalizing the regulator sizing.

Do not assume register-level compatibility with W5500 firmware: although both are WIZnet socket-register TOEs, the W6300's dual IPv4/IPv6 stack and high-speed host interface use a different register map and interface protocol. Porting requires updating drivers to the W6300 register definitions in the official datasheet, and the reset/boot pin sequence must be respected per the datasheet timing requirements.
