1893CKLFT

Overview

The 1893CKLFT is an Ethernet PHY integrated transceiver manufactured by Renesas Electronics. It supports 10BASE-T and 100BASE-TX standards with data rates of 10 Mb/s and 100 Mb/s. The device operates on a single 3.3 V power supply and features MII, MDI, and MDI-X interfaces. Housed in a 56-lead VFQFPN package, it functions within a temperature range of -40°C to +85°C. This component belongs to the 1893C series and includes one transceiver circuit for communication networking applications.

Feature Summary

• Integrated physical layer controller supporting 10/100 BASE-T/TX standards
• Single 3.3V power supply operation for simplified system design
• Supports MII, MDI, and MDI-X interface configurations

Applications

• Ethernet network interface cards
• Industrial control systems requiring wide temperature ranges
• Consumer electronics with 10/100 Mbps connectivity needs

Procurement Notes

Verify RoHS compliance status through official datasheets as documentation indicates detailed requirements. Confirm moisture sensitivity level (MSL) handling procedures before assembly. Ensure the specific suffix matches project requirements, as packaging variations exist. Cross-reference manufacturer part numbers to avoid confusion with legacy aliases like ICS1893CKILFT during sourcing.

Selection Notes

Select this component when a single-supply 3.3V Ethernet PHY is required for 10/100BASE-T applications. The VFQFPN-56 package suits space-constrained surface-mount designs. Verify that the industrial temperature range (-40°C to +85°C) aligns with environmental conditions. Check interface compatibility with the host processor's MII or RMII pins before finalizing the bill of materials.

Part Context

This part belongs to the Renesas 1893C series of Ethernet PHYceivers. It serves as a physical layer solution for connecting devices to twisted-pair Ethernet networks. The series provides integrated transceiver functionality, reducing the need for external magnetics in some configurations. It is designed for reliable data transmission in standard copper-based LAN environments.

Replacement Considerations

Check for direct pin-to-pin replacements within the 1893C family. Verify if updated revisions offer improved electrical characteristics or packaging options. Ensure any substitute maintains the same 3.3V supply requirement and VFQFPN-56 footprint for mechanical compatibility.
