1893YI-10LF

Overview

The Renesas 1893YI-10LF is a low-power, physical-layer device (PHY) supporting ISO/IEC 10Base-T and 100Base-TX standards. It operates on a single 3.3-V power supply with a voltage range of 3.1V to 3.5V. The component utilizes a 64-TQFP package and features an integrated MLT-3 encoder, NRZ/NRZI encoder, transmit wave shaping, and stream cipher scrambler. Designed for 0.35-micron CMOS technology, it typically consumes 400 mW of power.

Feature Summary

• Supports ISO/IEC 10Base-T and 100Base-TX Carrier-Sense Multiple Access/Collision Detection (CSMA/CD) protocols
• Integrates MLT-3 encoding, NRZ/NRZI encoding, and stream cipher scrambling functions
• Operates on a single 3.3-V power supply with low-power consumption characteristics

Applications

• Industrial Ethernet networks requiring 10 Mbps or 100 Mbps connectivity
• Embedded systems needing integrated physical layer solutions
• Network interface modules for consumer electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm RoHS compliance status as required by project specifications. Check for any product discontinuance notices from Renesas Electronics Corporation prior to finalizing procurement plans. Ensure compatibility with existing system voltage requirements.

Selection Notes

Select this component when a dedicated physical layer controller for 10/100 Base-T applications is required. Consider its low-power profile and integrated encoding capabilities for space-constrained designs. Evaluate the 64-TQFP package dimensions against available PCB real estate. Verify that the single 3.3-V supply aligns with the target system's power architecture.

Part Context

This part belongs to the IDT 1893 series of Ethernet PHYceivers manufactured by Renesas Electronics. These devices are designed to provide robust physical layer connectivity for standard Ethernet networks. The series integrates essential signal processing functions into a single chip, simplifying board design compared to discrete solutions.

Replacement Considerations

Consult official Renesas documentation for direct substitutes. Cross-reference pinouts and electrical characteristics carefully. Verify functional equivalence for 10Base-T and 100Base-TX support.
