1893BFILF

Overview

The 1893BFILF is a physical-layer device (PHY) manufactured by Renesas Electronics, belonging to the PHYceiver series. It supports ISO/IEC 10Base-T and 100Base-TX Ethernet standards with an MII interface. The component operates within a supply voltage range of 3.14 V to 3.47 V and functions at data rates of 10 Mb/s and 100 Mb/s. It features full and half duplex modes, consumes a maximum power dissipation of 400 mW, and draws up to 160 mA of current. The device is housed in a 48-SSOP package and operates between -40°C and +85°C.

Feature Summary

• Incorporates Digital-Signal Processing control in the Physical-Medium Dependent sub layer for enhanced signal integrity on unshielded twisted-pair cables.
• Supports Auto-MDIX functionality to automatically correct crossover errors in plant wiring without manual configuration.
• Provides a Serial-Management Interface for exchanging command and status information with Station-Management entities.

Applications

• MII Node applications requiring integrated Ethernet connectivity
• Network infrastructure equipment utilizing Category 5 cabling
• Industrial systems operating in extended temperature environments

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the source document matches the exact part number to avoid confusion with similar PHYceiver variants.

Selection Notes

Select this component for designs requiring a standalone 10/100 Mbps Ethernet PHY with MII compatibility. Verify that the system architecture supports the required 3.3V power domain and thermal management for 400mW dissipation. Check pinout compatibility with the target PCB layout for the SSOP package.

Part Context

This part belongs to the ICS1893 family of Ethernet PHY controllers from Renesas Electronics. It is functionally related to the ICS1893BF but may differ in packaging or commercial qualification. The PHYceiver series is designed for low-power, high-performance Ethernet connectivity solutions.

Replacement Considerations

The ICS1893BF is a documented alias for this component. Verify if the ILF suffix denotes a specific lead-free or tape-and-reel variant compared to standard tube packaging. Consult the manufacturer's obsolescence notices for potential end-of-life status.
