Device Overview

Summary

The KSZ9896 is a fully integrated layer 2, managed, six-port gigabit Ethernet switch with numerous advanced features. Five of the six ports incorporate 10/100/1000 Mbps PHYs. The sixth port has a MAC interface that can be configured as GMII, RGMII, MII or RMII. 

Full register access is available by SPI or I2C interfaces, and by optional in-band management via any of the data ports. PHY register access is provided by a MIIM interface.

Security features include support for IEEE 802.1X port-based authentication and Access Control List (ACL) filtering.

An assortment of power-management features including Energy-Efficient Ethernet (EEE) have been designed in to satisfy energy efficient environments.

Microchip's complimentary and confidential LANCheck® online design review service is available for customers who have selected our products for their application design-in. The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
