LAN9513I-JZX - USB 2.0 to 10/100 Ethernet Controller | Microchip
部品番号: LAN9513I-JZX ✓ 生産中LAN9513I-JZX 概要
A USB-to-Ethernet controller, also called an Ethernet bridge or USB network interface controller, is an interface IC that lets a host USB port present a standard 10BASE-T/100BASE-TX network connection to the outside world. Structurally it sits above the Ethernet PHY layer in the OSI hierarchy, and functionally it spans the USB device class, the Ethernet MAC layer and the physical layer, eliminating the need for a separate USB hub chip and a separate Ethernet interface component on the board.
Key features of the LAN9513I-JZX include Hi-Speed USB 2.0 compliance, full and half-duplex 10/100 Ethernet operation with flow control, automatic 32-bit CRC generation and checking, preamble generation and removal, IEEE 802.3 and 802.3u compliance, and an on-chip EEPROM controller for configuration storage. Because the hub and Ethernet functions share one silicon die, the device also delivers USB-to-USB pass-through, meaning one upstream USB port can expand into three downstream ports while still exposing a wired network link.
Internally, the LAN9513/LAN9513i family is partitioned into an upstream USB device controller, three downstream USB 2.0 PHY ports, a 10/100 Ethernet MAC with a full duplex-capable PHY, a TAP controller for test access and an EEPROM controller that emulates a 93C46/93C56 style serial EEPROM for host driver configuration. This partitioning allows a compact board area of roughly 9 x 9 mm of silicon for an entire network-and-USB connectivity block, which matters in docking stations, thin clients and embedded appliances where connector count is growing faster than board area.
Typical applications include USB-to-Ethernet adapters and dongles, laptop docking stations, set-top and game console accessories, industrial HMI panels, printers with network ports, and embedded Linux or RTOS systems that need a bridged network interface without adding a discrete Ethernet PHY plus magnetics footprint for each port.
When designing around this controller, treat the 64-QFN exposed pad as the primary thermal and layout feature: place input and decoupling capacitors close to the supply pins, keep the USB differential pair and Ethernet magnetics area separated from noisy switching nodes, and follow the reference layout and BOM in the manufacturer datasheet to preserve USB and Ethernet compliance.
This page brings together the manufacturer datasheet facts, a side-by-side comparison against the closest pin-compatible controllers, and practical PCB, thermal and layout guidance that a distributor catalogue page does not normally assemble in one place.

主な用途
LAN9513I-JZX の用途: 6 件s: USB-to-Ethernet Adapters and Dongles, Laptop and Desktop Docking Stations, Industrial HMI and Operator Panels, Printers and Networked Peripherals, Set-Top Boxes, Game Consoles and Media Gateways, Embedded Linux and RTOS Network Bridges.
USB-to-Ethernet Adapters and Dongles
The LAN9513I-JZX is a natural fit for a USB-to-Ethernet dongle because it merges the bridge function and the three-port USB 2.0 hub onto one 9 x 9 mm QFN die. The single upstream USB 2.0 PHY talks to the host while the integrated 10/100 Ethernet MAC and PHY drive an external 10BASE-T/100BASE-TX magnetics network, so the dongle needs only one controller, one Ethernet magnetics section and a handful of decoupling capacitors instead of a separate USB hub IC. Operating from a single 3.3 V rail across a 0 to 70 C ambient range suits consumer and lightly conditioned commercial adapters, while the integrated EEPROM controller keeps the device count and BOM cost down for high-volume dongles.
おすすめ
Laptop and Desktop Docking Stations
A docking station needs one upstream USB connection to deliver several downstream USB peripherals and a wired network link, which is exactly the topology the LAN9513I-JZX implements in a single package. The three integrated downstream Hi-Speed USB 2.0 PHYs remove the need for an external hub chip and its associated placement and power budget, while the 10/100 Ethernet controller provides network connectivity with full-duplex and half-duplex operation plus flow control and automatic 32-bit CRC checking. The 3.3 V single-supply architecture and 64-QFN (9 x 9 mm) footprint leave board area for display, audio and storage interfaces in a compact desktop accessory.
おすすめ
Industrial HMI and Operator Panels
Industrial human-machine interfaces increasingly ship with an Ethernet service port and several USB service connectors on the same board, and the LAN9513I-JZX delivers both from one device. The 10/100 Ethernet MAC and PHY are compliant with IEEE 802.3 and IEEE 802.3u and support preamble handling and CRC generation automatically, reducing the firmware burden in an embedded Linux or RTOS controller. Its 0 C to +70 C ambient rating covers indoor panel enclosures, and the integrated TAP controller gives production engineers boundary-scan and in-circuit debug access that is valuable when the panel contains a mix of USB peripherals. Use the manufacturer reference layout to separate the Ethernet magnetics from switching regulators.
おすすめ
Printers and Networked Peripherals
Printers and shared peripherals that add a USB-to-Ethernet port for service and network printing can use the LAN9513I-JZX to avoid building a discrete USB hub plus separate MAC and PHY chain. The integrated upstream USB 2.0 PHY handles the host connection, the three downstream PHYs serve front-panel USB ports, and the Ethernet controller delivers a compliant 10BASE-T/100BASE-TX interface to the network with flow control for busy traffic. Because the EEPROM controller is integrated, printer firmware can rely on a Microchip-supported enumeration path without adding a discrete configuration EEPROM, while the single 3.3 V supply keeps the auxiliary power tree simple.
おすすめ
Set-Top Boxes, Game Consoles and Media Gateways
Media devices need a reliable wired network option and a way to expose accessory USB devices, and the LAN9513I-JZX provides both in a single 64-QFN (9 x 9 mm) package that is easy to place beside a small SoC and its memory. The 10/100 Ethernet controller offers full-duplex operation with flow control and automatic CRC, which suits streaming traffic on consumer access networks, and the three downstream Hi-Speed USB 2.0 PHYs can serve controllers, storage or a camera module. The 3.3 V single rail and 0 to 70 C rating align with internal consumer electronics thermal conditions, and the small land pattern helps keep the enclosure footprint short.
おすすめ
Embedded Linux and RTOS Network Bridges
Embedded boards that previously carried a discrete USB hub plus an external Ethernet interface can consolidate onto the LAN9513I-JZX, shrinking the bill of materials and freeing board area for sensors or radios. The Ethernet MAC handles preamble generation and removal and automatic 32-bit CRC generation and checking, so the network stack sees a standard interface instead of a low-level driver burden, and the EEPROM controller simplifies boot-time configuration of the USB descriptors. The TAP controller supports boundary scan in production, which shortens bring-up on multi-board assemblies, and the single 3.3 V supply is convenient for systems already running a 3.3 V core rail.

設計ノート
Treat the exposed pad of the 64-QFN (9x9) as a full ground plane connection, not a thermal afterthought. Place the input and internal decoupling capacitors adjacent to the supply pins, keep the Ethernet magnetics and their traces on the opposite side of the board from the USB differential pairs, and follow the reference layout in the manufacturer data brief. USB and Ethernet both depend on controlled-impedance routing; a compromised return path under the Ethernet magnetics is a common cause of CRC and retry errors that look like firmware bugs.
The LAN9513I-JZX runs from a single 3.3 V rail, and the hub PHYs, Ethernet MAC and PHY all draw from that same domain. Provide the minimum required decoupling capacitance at the supply pins and reserve additional bulk capacitance close to the USB connector and the Ethernet magnetics to absorb plug-in and link-up transients. If your board also feeds USB downstream ports from the same 3.3 V rail, budget the port current separately so the rail does not sag during hot-plug events, which can force USB enumeration retries.
Two frequent design errors are assuming an external configuration EEPROM is required and assuming that any 64-QFN controller can be substituted. The LAN9513 family integrates an EEPROM controller, so adding a discrete EEPROM that is not in the reference BOM can leave the device unmapped. On the other hand, the LAN9514, LAN9512 and LAN7801 packages match physically but differ in auxiliary blocks and USB speed. Always re-check the pin description table and register map in the manufacturer datasheet for the exact ordering code before releasing a swap.
Keep the upstream USB 2.0 differential pair short, tightly coupled and referenced to a continuous ground plane, and route the downstream port pairs away from the Ethernet transformer and its switching nodes. Because the same die carries hub, MAC and PHY logic, any ripple on the 3.3 V rail appears as noise on both the USB and Ethernet data paths. Star the magnetics supply return directly to the ground plane and keep ferrite beads and inductors on the USB branch away from the Ethernet branch to limit crosstalk between the two protocols.
Estimated: with a 3.3 V supply and a 10/100 link running at roughly 60 mA average for the PHY and controller sections, the internal dissipation is on the order of 0.2 W, so the 64-QFN exposed pad is normally adequate without a heat sink. Confirm the actual worst-case supply current from the manufacturer data brief for your operating mode, and provide a solid ground pour under the pad with thermal vias to spread the small amount of heat generated, which also improves the exposed-pad soldering reliability during reflow.
