The KSZ8893MQL is a standalone sub-microcontroller designed to provide local bus switching and high performance control to applications with a minimum of complexity. It is a high-performance, low-power Ethernet-class switch controller with multifunctional capabilities. The KSZ8893MQL is ideal for applications such as industrial networking, audio, video, and security.

The KSZ8893MQL offers various connectivity options, including 10/100/1000 Base-T Interface, USB 2.0 Interface and Ethernet 10/100/1000 Base-T interface. The embedded Ethernet MAC/PHY is compliant with the IEEE 802.3 standards and the USB 2.0 interface implements the enhanced host controller interface (EHCI) specification. The switch controller\'s advanced filter engine allows configurable filtering of Ethernet packets at up to 16K MAC-level entries with up to 64K IPV4/IPV6 address entries.

The KSZ8893MQL can be configured to offer different levels of QOS (Quality of Service) depending on the type of application. It supports four independent queues with different levels of traffic prioritization and separate acceptance filters. The controller can accept and prioritize VoIP and streaming multimedia traffic, allowing it to efficiently manage real-time applications End-to-End QoS.

The switch controller includes hardware-based address look-up (ALU) block integrated with packet processing functional blocks. The ALU supports up to 512 entries for forward/broadcast/multicast packets, and up to 4096 entries for multicast streams. The KSZ8893MQL is capable of processing fast frames up to 12288 bytes and jumbo frames of up to 1536 bytes. It also has a switch fabric port that can support up to 8Gpbs backplane I/O.

Moreover, the KSZ8893MQL offers integrated Layer-2 switch features, such as automated Source/Destination MAC address learning/aging, VLAN support, Port-security, Port-mirroring, MAC-speciific forwarding. It also provides a variety of optional port-configurations, such as an integrated RMON, enabling real-time monitoring of switch ports.

In addition, the KSZ8893MQL has a set of advanced software features that help monitor, manage, configure and control the switch. It includes a protocol-based (L2-L4) packet processing engine, which can be utilized for implementing various packet-oriented features. It also has an embedded HTTP-server function, which allows the switch to be configured and managed via any standard web browser. The KSZ8893MQL also integrates a global timer to enable accurate time-stamping of all incoming packets.

Overall, the KSZ8893MQL provides a powerful, low-power, feature rich solution for applications needing high performance bus switching and control. The integrated Ethernet MAC/PHY, USB Interface and Ethernet 10/100/1000 Base-T) interfaces offer a cost-effective solution for connecting multiple connected devices in industrial and home applications. Additionally, the switch controller includes integrated hardware-based address look-up (ALU) block, advanced software features, and a set of optional port-configurations for a comprehensive and secure networking experience.
