VSC8540XMV-05

Overview

The VSC8540XMV-05 is a single-port industrial-grade Fast Ethernet copper PHY supporting 10/100BASE-TX standards. It features RGMII, MII, and RMII MAC interfaces with SyncE and IEEE 1588 time stamp support. The device operates within a temperature range of -40°C to +125°C and utilizes a QFN-68 package. Key electrical parameters include a supply voltage range of 950 mV to 1.05 V for specific domains and a maximum power consumption of 35 mA.

Feature Summary

• Supports Synchronous Ethernet (SyncE) and IEEE 1588 Precision Time Protocol for network synchronization.
• Integrates ActiPHY power management technology to enable low-power states and link partner wake-up capabilities.
• Includes VeriPHY cable diagnostics for automated media fault detection and testing.
• Provides Start of Frame (SOF) indication specifically for the VSC8540-05 variant.

Applications

• Industrial automation networks requiring extended temperature operation
• Telecommunications equipment utilizing Synchronous Ethernet
• Power-over-Ethernet (PoE) enabled switches and endpoints
• Embedded systems requiring precise time synchronization

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct channels. Confirm that the ordering suffix matches the required industrial temperature grade (-40°C to +125°C). Ensure compatibility with the target system's voltage domains and interface requirements before finalizing procurement orders.

Selection Notes

Select this model when industrial temperature ratings are mandatory. Verify that the host processor supports RGMII, MII, or RMII interfaces. Consider the power budget as the device draws up to 35 mA. Ensure the application benefits from SyncE or IEEE 1588 support if timing accuracy is critical for the network topology.

Part Context

This component belongs to the VSC8540 series of Fast Ethernet PHYs. It is distinct from radiation-tolerant variants like the VSC8540XMVRT-SV. The '05' suffix denotes the industrial temperature range extension compared to commercial grade options. It serves as a physical layer transceiver for connecting MAC controllers to twisted-pair copper cabling.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the VSC8540 family for pin-compatible alternatives if different temperature grades or interface configurations are required. Consult official Microchip documentation for detailed cross-reference data.
