KSZ8765CLXCC

Controllers Overview

The KSZ8765CLXCC is a Layer 2-managed, five-port Ethernet switch designed for cost-sensitive applications. It integrates four 10/100 Mbps copper ports (Port 3 and Port 4) and two 100 Mbps fiber ports (Port 1 and Port 2), alongside one Gigabit uplink port (Port 5). The device features an 80-pin LQFP package and operates within a commercial temperature range of 0°C to +70°C. Key specifications include a 64KB frame buffer RAM, a 1024-entry forwarding table, and support for IEEE 802.1q VLANs with up to 128 active groups. Power management includes Energy Detect Power Down (EDPD) and IEEE 802.1az EEE.

Controllers Feature Summary

• Integrated MAC/PHY transceivers for copper and fiber interfaces
• Non-blocking store-and-forward switch fabric with 64KB memory
• Advanced security via ACL filtering and 802.1x authentication
• Comprehensive power management including EEE and Wake-on-LAN

Controllers Applications

• Industrial Ethernet applications (Ethernet/IP, Profinet)
• VoIP phones and IPTV set-top boxes
• Broadband gateways and wireless LAN access points
• Standalone 10/100 switches and networked control systems

Controllers Procurement Notes

Verify the specific ordering suffix 'CC' confirms the commercial temperature grade (0°C to +70°C) and 80-pin LQFP package. Ensure compatibility with existing system voltage requirements, specifically the 3.3V analog supply and 1.2V core voltage. Confirm that the lead-free RoHS compliance meets environmental standards for the target deployment region.

Controllers Selection Notes

Select this component when a managed switch solution is required for mixed copper and fiber environments. The integrated PHYs eliminate external transceiver costs. Consider the 80-pin LQFP footprint for board space constraints. Verify that the SPI or MDC/MDIO management interface aligns with the host controller's available communication protocols.

Controllers Part Context

This part belongs to the KSZ8765CLX family manufactured by Micrel, now part of Microchip Technology. The 'CC' suffix denotes the commercial temperature variant, distinct from the industrial 'IC' version which supports -40°C to +85°C. It serves as a highly integrated solution replacing discrete switch and PHY components in broadband and industrial networking designs.

Controllers Replacement Considerations

The KSZ8765CLXIC is the direct industrial temperature equivalent within the same package and pinout. For upgrades, verify if the KSZ8795 series offers necessary feature enhancements while maintaining software compatibility.
