Microchip LAN9303I-ABZJ is a 3-port 10/100 Ethernet Switch IC designed in a compact 56-pin QFN package measuring 8 mm length and width by 1 mm height. Operating at a fixed 3.3 V supply voltage, it supports network speeds up to 200 Mbps with full duplex and half duplex communication modes, compliant with IEEE 802.3 standards for Ethernet interface.
This switch IC features a Turbo MII interface allowing flexible speed management alongside an internal loopback mode for diagnostic purposes. It supports advanced networking functionalities including IEEE 802.1Q VLAN with up to 16 VLAN groups, and IGMP v1/v2 for multicast packet filtering.
Robustness is enhanced by integrated ±8kV/15kV electrostatic discharge (ESD) protection on each port, making it suitable for demanding industrial, manufacturing, networking equipment, and commercial Ethernet applications. The device is surface mountable on PCBs via its QFN package with 56 pins, optimizing space usage in compact electronic designs.
It incorporates virtual PHY features that simplify software development by emulating multiple switch ports as a single PHY port. The LAN9303I-ABZJ also offers extensive network management capabilities through 42 per-port Management Information Base (MIB) counters.
This Ethernet switch IC is ideal for implementing efficient network switches requiring managed control in industrial communications and embedded systems. Compact footprint suitable for space-constrained applications. High-speed network support up to 200 Mbps ensures fast data transfer rates.
Supports VLAN for efficient network traffic segmentation and security. Effective multicast monitoring via IGMP filters for network optimization. Robust ESD protection extends device reliability in industrial environments.
Compatible with surface mount technology for streamlined PCB assembly. Targeted for industrial, networking, commercial, and manufacturing use cases. Reduction of software development complexity via virtual PHY functionality.
