1893CFLF

Overview

The 1893CFLF is an integrated Ethernet PHYceiver manufactured by Renesas Electronics, designed for 10/100 BASE-TX applications. It operates on a single 3.3V power supply and supports data rates of 10 Mb/s and 100 Mb/s. The device features MII interface compatibility and includes built-in auto-negotiation capabilities. It is housed in a 48-SSOP package with dimensions of 15.9 x 7.5 x 2.3 mm. The component supports full and half duplex modes and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Integrated physical layer transceiver supporting 10BASE-T and 100BASE-TX standards
• Built-in auto-negotiation for automatic link speed and duplex configuration
• Single 3.3V power supply operation for simplified system design
• MII interface compatibility for direct connection to MAC controllers

Applications

• Network Interface Cards (NICs)
• PC motherboards
• Switches and routers
• DSL and cable modems
• Game machines

Procurement Notes

Verify the specific suffix 'LF' indicates lead-free compliance against the official datasheet revision history. Confirm the 48-SSOP package variant matches the required footprint. Check for any recent Product Change Notices regarding pinout or electrical parameter updates. Ensure the source document explicitly lists the 1893CFLF part number as active or available.

Selection Notes

Select this component when a compact, single-chip solution for 10/100 Mbps Ethernet connectivity is required. It is suitable for designs needing integrated auto-negotiation without external PHY components. Consider the 48-SSOP package constraints for PCB layout. Verify that the 0°C to 70°C operating range meets the environmental requirements of the target application.

Part Context

The 1893CFLF belongs to the Renesas 1893C series of Ethernet PHYceivers. This family integrates the physical layer transceiver and auto-negotiator into a single IC. The series is commonly used in consumer electronics and industrial networking equipment requiring reliable 10/100BASE-TX connectivity.

Replacement Considerations

The 1893CFLFT is a tape-and-reel version of the same component. The 1893CKILFT offers the same functionality in a VFQFPN-56 package. Verify pin-to-pin compatibility before substitution.
