1893AFILF

Overview

The 1893AFILF is an Ethernet Physical Layer Controller manufactured by Renesas Electronics Corporation, designed for 10/100 Base-T/TX applications. It integrates a PHY transceiver with a parallel interface for network connectivity. The component operates within a supply voltage range of 3.14V to 3.47V and supports data rates of 10 Mb/s and 100 Mb/s. It utilizes an MDI or MDI-X interface and is housed in a 48-BSSOP package with a width of 0.295 inches (7.50mm). The device functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a single Ethernet transceiver for 10/100 Base-T/TX standards
• Provides a parallel interface for direct connection to network controllers
• Supports standard MDI and MDI-X pin configurations

Applications

• Ethernet physical layer implementation in network equipment
• Industrial control systems requiring 10/100 Mbps connectivity
• Embedded networking solutions with parallel bus interfaces

Procurement Notes

Verify the specific suffix 'FILF' against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with required operating voltage ranges and temperature grades before integration. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.

Selection Notes

Select this component when a dedicated Ethernet PHY with a parallel interface is required for 10/100Base-T/TX networks. It is suitable for designs needing integrated transceiver functionality without external magnetics complexity. Confirm that the host controller supports the necessary parallel data bus signals and timing requirements specified in the electrical characteristics.

Part Context

This part belongs to the 1893C series of Ethernet ICs from Renesas Electronics. It serves as a physical layer solution for legacy and industrial Ethernet deployments. The series typically includes variants with different packages or interface options, maintaining core PHY functionality across the family while adapting to specific board layout or system integration needs.

Replacement Considerations

The 1893CKILFT is a documented variant within the same product line, offering similar Ethernet PHY functionality but potentially differing in package configuration or specific interface parameters. Verify mechanical footprint and electrical signal integrity before substitution.
