Overview
The Renesas Electronics Corporation 1894KI-33LFT is an Ethernet PHY controller belonging to the PHYceiver series. It supports 10/100 Base-T/TX standards with a single transceiver and RMII interface. The device operates on a 3.3V power supply, typically ranging from 3.14V to 3.47V. It is housed in a 32-pin VFQFPN package (5x5 mm) with an exposed pad for thermal management. The component functions within a commercial temperature range of 0°C to 70°C. It complies with RoHS3 specifications and has a Moisture Sensitivity Level (MSL) of 3 (168 hours).
Feature Summary
- Supports 10/100 Base-T/TX Ethernet physical layer transmission.
- Integrates a single transceiver with RMII interface capability.
- Operates at standard 3.3V logic levels.
Applications
- Ethernet network connectivity modules.
- Industrial communication devices requiring 10/100 Mbps links.
- Consumer electronics with embedded networking capabilities.
Procurement Notes
Verify the specific suffix 'LFT' against official Renesas documentation to confirm lead-free status and tape-and-reel packaging configuration. Cross-reference the part number with current product discontinuation notices or PCNs, as legacy components may have limited availability or end-of-life status. Ensure compatibility with existing board designs regarding the 32-VFQFPN footprint and thermal requirements.
Selection Notes
Select this component when a 3.3V powered Ethernet PHY with RMII interface is required. Compare against the 1894K-32LFT variant if industrial temperature ranges (-40°C to 85°C) are necessary instead of the commercial range. Verify package dimensions match the 5x5 mm VFQFPN specification. Confirm that the single transceiver architecture meets the system's port density needs.
Part Context
This part belongs to the Renesas PHYceiver family of Ethernet controllers. It is related to other variants such as the 1894KI-40LFT, which offers a different pin count and package size. The 'KI' designation typically indicates specific feature sets or package types within the broader 1894 series portfolio managed by Renesas Electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult Renesas official documentation for direct replacements or obsolescence management strategies.
