Description

LAN9730-ABZJ is a 10/100 Mbps Ethernet controller (MAC/PHY) in the LAN9730 family, designed for embedded systems that need Ethernet connectivity. It provides the IEEE 802.3u MAC and PHY in one chip and exposes a host interface (such as MII/RMII or a similar data interface) for a microcontroller or processor to drive. Typical use is to add network capability to MCUs/SoCs without built-in Ethernet MAC/PHY. The “-ABZJ” suffix generally encodes packaging, temperature rating, and lead-free options (industrial/commercial grades may vary by supplier). For exact pinout, electrical specs, and interface details, consult the vendor’s datasheet and application notes. In short: a compact, integrated MAC/PHY Ethernet solution for embedded and industrial designs.

Features

Here are the typical features of LAN9730-ABZJ (Ethernet PHY/MAC chip):
- 10/100 Mbps Ethernet MAC + PHY (IEEE 802.3/802.3u compliant)
- Auto-Negotiation with speed/duplex selection (10BASE-T and 100BASE-TX)
- Media interfaces: MII and/or RMII selectable; MDIO/MDC management interface
- Integrated TX/RX PHY with standard PHY LEDs (Link, Activity)
- Low-power/standby modes for power savings
- Energy Efficient Ethernet (EEE) support where available
- Robust electrical protection (ESD/EMI) and wide operating conditions
- RoHS-compliant, packaged as ABZJ variant (specific package/temperature per datasheet)
Note: exact package, voltage ranges, and pinout are defined in the full datasheet for the ABZJ variant.

Package

LAN9730-ABZJ uses a 48-pin LQFP package (LQFP-48).

Pinout

- Pin count: 64 pins (LQFP-64, package code ABZJ).
- Function: LAN9730-ABZJ is a 10/100 Mbps Ethernet MAC/PHY controller (IEEE 802.3) with an MDIO/MDC management interface; connects to a host MCU via MII/RMII and provides the Ethernet PHY for network connectivity.

Manufacturer

Manufacturer: Standard Microsystems Corporation (SMSC), now part of Microchip Technology. SMSC is a fabless semiconductor company that designs and markets networking ICs (e.g., Ethernet and USB controllers).

Equivalent

LAN9730-ABZJ is a USB 2.0 to 10/100 Ethernet MAC/PHY controller (SMSC/Microchip). Direct cross-references are limited, but close replacements include:
- Microchip/SMSC LAN9512 and LAN9514 (USB 2.0 to Ethernet with hub)
- ASIX AX88772/AX88772B (USB-to-10/100 Ethernet)
- Realtek RTL8152/RTL8153 (USB-to-Ethernet controllers)
Note: check exact USB interface, package/pinout, PHY/MAC features, and firmware compatibility; not every part is a drop-in replacement.
