LAN9730I-ABZJ

Microchip Technology

LAN9730I-ABZJ is a Microchip LAN9730i High-Speed Inter-Chip (HSIC) USB 2.0 to 10/100 Ethernet controller — integrated 10/100 MAC and PHY with HP Auto-MDIX, in 56-pin VQFN (8 × 8 mm), tray packing (ABZJ; TR is the reel version), single 3.3 V supply, -40 to +85 °C. Single-chip MAC plus PHY is the selection point: one device replaces the MAC-plus-external-PHY two-chip solution for adding Ethernet to embedded hosts. Selection advice: the host interface is HSIC, not standard USB 2.0 — confirm your SoC provides an HSIC port, otherwise choose a USB-based controller (LAN951x family) or an SPI Ethernet controller (ENC28J60) instead. The integrated PHY with auto-MDIX removes the magnetics-configuration headache, and wakeup-packet plus link-status-change detection suits low-power and remote-management designs. Evidence: Microchip LAN9730 datasheet and distributor listings confirm HSIC USB 2.0 to 10/100 Ethernet, integrated MAC+PHY, 56-VQFN and 3.3 V. Match the full LAN9730I-ABZJ code for the industrial grade and tray packing.

SELECTION GUIDANCE

LAN9730I-ABZJ selection guidance

LAN9730I-ABZJ is a USB to Ethernet controller from Microchip Technology, orderable in the VQFN-56 package. The ordering code fixes the exact configuration you receive — package, grade and packing — so procurement starts with matching this code character-for-character against your BOM, not just the base series name.

When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

COMMON QUESTIONS

LAN9730I-ABZJ FAQ

What do the suffixes in LAN9730I-ABZJ mean?

Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. LAN9730I-ABZJ names the VQFN-56 configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.

What is the difference between package and packing for LAN9730I-ABZJ?

The package (VQFN-56) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.

Can you provide traceability documents for LAN9730I-ABZJ?

Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.

How do I request a quotation for LAN9730I-ABZJ?

Add LAN9730I-ABZJ to your RFQ with the complete ordering code, the manufacturer (Microchip Technology), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
