KSZ8842-32MVLI

Controllers Overview

The KSZ8842-32MVLI 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 10/100 transceivers. It operates on a single 3.3V power supply within an industrial temperature range of -40°C to +85°C. The component is housed in a 128-pin LQFP package.

Controllers Feature Summary

• Supports advanced Layer-2 managed switching capabilities including VLAN tagging and QoS prioritization.
• Provides low-latency repeater mode suitable for latency-critical embedded applications.
• Includes comprehensive monitoring features such as port mirroring and MIB counters.

Controllers Applications

• Video over IP systems
• Industrial control in latency critical applications
• Security and surveillance cameras

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout compatibility and electrical specifications. Ensure that the procurement channel provides original manufacturer packaging to maintain component integrity during storage and handling.

Controllers Selection Notes

Select this model when a non-PCI interface is required for system integration. The 32-bit bus width distinguishes it from the 16-bit variant. Confirm that the application environment falls within the specified industrial temperature range and voltage requirements before finalizing the design.

Controllers Part Context

This component belongs to the KSZ8842M series of fully managed two-port switches. It serves as an alternative to PCI-based solutions by offering a generic host interface. The series integrates MAC units, PHYs, and a non-blocking switch fabric into a single chip.

Controllers Replacement Considerations

The KSZ8842-16MVLI is a compatible alternative if the system utilizes an 8-bit or 16-bit bus interface instead of the 32-bit interface found in the KSZ8842-32MVLI. Verify interface width compatibility before substitution.
