1894K-32LFT

Overview

The Renesas Electronics Corporation 1894K-32LFT is an Ethernet Physical Layer Controller belonging to the PHYceiver series. It functions as a 10/100 Base-T/TX PHY transceiver designed for parallel interface connectivity. The device 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 is housed in a 32-VFQFPN package with dimensions of 5x5 mm and features a bare pad. The component is rated for an operating temperature range of 0°C to 70°C and holds a Moisture Sensitivity Level (MSL) classification of 3, corresponding to a reflow duration of 168 hours.

Feature Summary

• Integrated 10/100 Base-T/TX physical layer transceiver functionality
• Supports parallel interface connection for system integration
• Complies with RoHS3 specifications

Applications

• Ethernet network interface implementation
• Industrial communication systems
• Consumer electronics networking modules

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct package and tape-and-reel configuration. Confirm current lifecycle status, as discontinuation notices indicate potential end-of-life timelines. Validate that the selected variant matches the required 32-VFQFPN package and commercial temperature range specifications before finalizing procurement orders.

Selection Notes

Select this component when a dedicated 10/100 Mbps Ethernet PHY with a parallel interface is required. Ensure the host system provides a compatible parallel bus and operates within the specified 3.14V to 3.47V voltage window. Verify that the application environment remains within the 0°C to 70°C operating temperature limits and that the 32-pin VFQFPN footprint fits the design constraints.

Part Context

This part belongs to the Renesas PHYceiver series, which focuses on integrated Ethernet physical layer solutions. The 1894K base number identifies the specific family architecture. The -32LFT suffix denotes the 32-pin VFQFPN package type and tape-and-reel packaging format. This distinguishes it from other pin counts or bulk packaging variants within the same functional family.
