TL82543GCSL4AC

Controllers Overview

The Intel TL82543GCSL4AC is a Gigabit Ethernet controller component belonging to the Intel 8254x series. It provides single-port connectivity via an RJ-45 interface supporting 10/100/1000 Mbps speeds. The device utilizes a PCI-X system interface for data transmission and operates within a commercial temperature range of 0°C to 70°C. This controller integrates standard network features such as Wake-on-LAN and hardware checksum offload capabilities to reduce CPU overhead during high-throughput network operations.

Controllers Feature Summary

• Supports full-duplex and half-duplex Gigabit Ethernet operation with auto-negotiation capabilities.
• Integrates hardware-based checksum offload engines to minimize processor utilization during packet processing.
• Includes Wake-on-LAN functionality allowing remote system activation via specific network frames.

Controllers Applications

• Desktop computer motherboard integration
• Industrial PC networking modules
• Server expansion cards

Controllers Procurement Notes

Verify the exact suffix against official Intel documentation to confirm package type and temperature grade. Ensure compatibility with the target system's PCI-X slot voltage requirements. Confirm that the specific revision matches the required driver support matrix for the intended operating environment before finalizing acquisition.

Controllers Selection Notes

Select this component when a PCI-X interface is required rather than PCIe. Compare against the 82546GB series if higher performance or PCIe connectivity is needed. Verify that the single-port configuration meets the bandwidth requirements of the application without necessitating link aggregation.

Controllers Part Context

This part belongs to the Intel 8254x family of Gigabit Ethernet controllers, which succeeded earlier models like the 82540 series. These components were widely deployed in early-to-mid 2000s computing platforms. The 82543GC variant specifically targeted cost-sensitive desktop and entry-level server markets requiring reliable Gigabit connectivity over legacy PCI-X buses.

Controllers Replacement Considerations

Direct pin-compatible replacements are limited due to the legacy PCI-X interface. Modern systems typically utilize PCIe-based controllers such as the I210 or I211 series. If upgrading, verify that the new controller supports the necessary operating system drivers and physical form factor constraints of the existing chassis or motherboard.
