KSZ8852

The KSZ8852 product line consists of industrial capable Ethernet switches, providing integrated communication for a range of Industrial Ethernet and general Ethernet applications.

The KSZ8852 product enables distributed, daisy-chained topologies preferred for industrial Ethernet networks. Conventional centralized (i.e., star-wired) topologies are also supported for fault tolerant arrangements. A flexible 8- or 16-bit general bus interface is provided for interfacing to an external host processor.

The wire-speed, store-and-forward switching fabric provides a full complement of QoS and congestion control features optimized for real-time Ethernet. The KSZ8852 product is built upon Microchip's industry-leading Ethernet technology, with features designed to offload host processing and streamline your overall design:

- Wire-speed Ethernet switching fabric with extensive filtering
- Two integrated 10/100BASE-TX PHY transceivers, featuring the industry’s lowest power consumption
- Full-featured QoS support Flexible management options that support common standard interfaces

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

Note: PTP should be disabled during compilation when using the driver listed below.
