1894K-33LF

Overview

The 1894K-33LF is an Ethernet PHY controller manufactured by Renesas Electronics Corporation, belonging to the PHYceiver series. It supports 10/100 Base-T/TX standards with a parallel interface and operates on a 3.3V supply voltage (3.14V to 3.47V). The device is housed in a 32-VFQFPN package with exposed pad (5x5 mm) and functions within a commercial temperature range of 0°C to 70°C. It includes one transceiver for Ethernet communication.

Feature Summary

• Integrated physical layer controller for Ethernet connectivity
• Supports standard 10/100 Base-T/TX data rates
• Utilizes parallel interface for host connection

Applications

• Ethernet network interface design
• Industrial control systems requiring 10/100 Mbps connectivity
• Consumer electronics with Ethernet ports

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to project requirements. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this component when a parallel interface PHY is required for 10/100 Ethernet applications. Consider the 32-pin VFQFPN package constraints and the 0°C to 70°C operating temperature range against system environmental conditions. Verify power supply stability within the specified 3.14V to 3.47V window.

Part Context

This part is part of the Renesas PHYceiver family, designed for cost-effective Ethernet solutions. It serves as a physical layer transceiver, bridging MAC controllers to twisted-pair cabling. The 1894K variant specifically denotes the package and temperature grade configuration within the broader product line.

Replacement Considerations

Check for updated suffixes or pin-compatible alternatives from Renesas if availability is limited. Verify electrical compatibility and interface signals before substituting with other PHY controllers.
