KSZ8842-32MVL

Controllers Overview

The KSZ8842-32MVL is a two-port Ethernet switch and repeater from Microchip Technology, designed for non-PCI CPU interfaces. It supports IEEE 802.3u standards with data rates of 10 Mb/s and 100 Mb/s. The device features a flexible 32-bit generic host processor interface and includes two integrated 10/100 transceivers. It operates on a single 3.3V power supply within a voltage range of 3.1 V to 3.5 V. The component is housed in a 128-pin LQFP package and functions reliably across a commercial temperature range of 0°C to +70°C.

Controllers Feature Summary

• Supports advanced Layer-2 management features including VLAN tagging, QoS prioritization, and spanning tree protocol.
• Configurable as a low-latency repeater or a fully managed switch with store-and-forward architecture.
• Includes comprehensive monitoring capabilities such as port mirroring, MIB counters, and loopback modes.

Controllers Applications

• Video distribution systems
• Industrial control sensor devices
• Security and surveillance cameras

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product identification system to ensure correct bus width and package configuration. Confirm that the required temperature grade matches the application environment before finalizing procurement orders.

Controllers Selection Notes

Select this model when a non-PCI interface is required for the host processor connection. Ensure the design accommodates the 128-pin LQFP footprint and provides adequate thermal dissipation for the specified operating conditions.

Controllers Part Context

This part belongs to the KSZ8842 series of two-port Ethernet switches. It serves as an alternative to PCI-based variants by offering a generic bus interface suitable for embedded processors. The -32 suffix specifically denotes support for a 32-bit data bus width.

Controllers Replacement Considerations

The KSZ8842-16MVLI is a compatible variant within the same family but utilizes an 8/16-bit bus interface instead of the 32-bit interface found in the KSZ8842-32MVL.
