Product Description

Microchip LAN9311I-NZW is a highly integrated 2 port Ethernet Switch IC designed to combine the core functionalities of a 10/100 Mbps switch into a compact 128-pin XVTQFP package. It supports data rates up to 100 Mbps with full duplex and half duplex communication modes, making it suitable for various embedded networking applications.

This Switch IC operates over a supply voltage range of 1.8 V to 3.3 V, ensuring compatibility with low voltage embedded systems. The device includes advanced features such as VLAN support, QoS packet prioritization, rate limiting, and IGMP monitoring, enabling efficient network traffic management.

The LAN9311I-NZW integrates two 10/100 PHY transceivers with high-performance auto-MDIX capability, simplifying connection requirements and enhancing flexibility. A hardware IEEE 1588 time stamp unit is incorporated for precise timing synchronization in networked systems.

Designed for surface mount applications, the device has a compact footprint with a 14.2 mm square outline and a low profile of 1.2 mm. Its operating temperature range of -40°C to 85°C makes it suitable for industrial and commercial environments.

This IC interfaces easily with most 16-bit embedded CPUs via a host bus interface, simplifying integration into existing systems. Power management features are included to optimize consumption in embedded networking devices.

Supports VLAN, QoS packet prioritization, and IGMP monitoring for advanced network functionality. Compliant with IEEE 802.3 and 802.1D/Q standards ensuring wide compatibility. High performance switching fabric and buffer management on-board.

Includes integrated PHY transceivers with jack auto-negotiation and HP Auto-MDIX support. Compact 128-pin XVTQFP surface mount package for space-constrained designs. Operating voltage range from 1.8 V to 3.3 V suits modern low voltage systems.

Temperature rating -40°C to 85°C enables use in harsh environments. Typical supply current is 185 mA during data operation. Applications include industrial Ethernet switches, embedded networking devices, and communication systems requiring compact high performance network interfaces.
